NBW VOPK DEDICATED TO MY DEAR COLLEAGUE DR. THEODOR AXENFELD Professor of Ophthalmology and Chief of the Ophthalmic Clinic in the University of Freiburg In Remembrance of true and unbroken friendship since the days of student life Preface. Foe years, in conjunction with the sculptor, F. Koi- bow, I have endeavored to perpetuate in wax models the appearance of important external diseases of the eye. Because of the delicacy and sensitivity of oph- thalmic tissues, the difficulties to overcome were, nat- urally, very great, and only after much experiment were we able to discover the correct method. The request of the publishers, Urban & Schwarz- enberg, to prepare an Atlas of the most important external diseases of the eye was acceded to only when I was convinced that modern art could produce pic- tures of distinctly better technic than those hitherto published. The plates were obtained by making, after a special method, a mask of the living subject, which was then filled with wax. From the wax models photographic reproduction in four colors was made. We thus gain two advantages, viz., we have before us, not a schematic representation, but the actual case as it appeared in the University Ophthalmic Clinic of the Berlin Charite Hospital of which I am chief, and, so to speak, no man's hand has touched it. Further- more, by means of the models, we get a pictorial plas- ticity unattainable by the most accomplished draughts- man. Although the work appears under my name, I am fully conscious that only a portion thereof is actually mine. To the skill, powers of observation and zealous par- ticipation of Sculptor Kolbow (Berlin), success in obtaining the beautiful plates is largely due. He is, probably, surpassed by no one to-day in the fabrica- tion of wax models. A number of the false eyes inserted into the models simulate the pathologic aspect of the organ, and were prepared in accordance with my specifications by the optical firm of Miiller Bros. (Wiesbaden) and by Hans Huning (Berlin). The drawings were made by the expert scientific draughtsman, H. Helbig. The execution of the plates in color was undertaken by the firm of Dr. Selle & Co. The difficulties here were so great that at first many of the plates were necessarily rejected. Finally, I may mention with commendation the willingness of the firm to make all alterations and corrections, and that, too, with no diminution of its productive ability. The printing of the plates was most carefully and satisfactorily accomplished by the firm of Doring & Huning (Berlin). Figs. 4 and 5 were taken from Bockenheimer's Atlas of Surgical Diseases, and Fig. 8 from the Atlas of Skin Diseases by Jacobi, both of which works are pub- lished by the same house. Last, but not least, an expression of my gratitude and content is due the publishers. Urban & Schwarz- enberg, who, notwithstanding the enormous expense of the undertaking, have invariably sought to conjoin in the work the best offered by modern science and technic, neglecting no method or experiment necessary to such accomplishment. We hope for a substantiation of our aim in prepar- ing this volume. Pbof. R. Gbeeff. Berlin, February, 1909. VIU. rcclf. Alias. Fig. 1. Erysipelas Faciei — Oedema palpebrarum ?L-biii.Tii Company, New York Erysipelas Faciei, Oedema Palpebrarum. Plate I., Fig. 1. Facial erysipelas, also called St. Anthony's fire (German: Gesichtsrose, Rotlauf), follows, commonly, some slight injury of the skin (vesicle, bleb, eczema, excoriations, rhagades), which serves as a point of entry for the streptococcus erysipelatis. With high fever, sometimes with chills, there develops a sharply- contoured, glistening red swelling of the skin, which extends rapidly, and at last, usually involves the entire face. Within a short time the epiderm is raised up in few or many blebs. The eyelids present a markedly reddened skin ; upon their margins the blebs are particularly apt to develop (Fig. 1, right eye) ; and there is great timief action, so that, as a rule, the eyes cannot be opened. The ex- treme inflammatory palpebral edema is due to the loose connection here betwixt the skin and the underlying tissues, to the absence of subcutaneous fat, and to the fact that there is present abundant space for the ex- tension of a tumef active process (C/. infra: Edema). Commonly, the temperature gradually falls after a few days ; the blebs or vesicles break, and, with retro- gression of the redness and swelling, there begin ex- foliation and pigmentation of the affected areas. The diag'nosis is easily made. The simultaneous appearance of fever with rubescent and glistening skin renders error difficult. 1 The progri^osis is, in general, good, but should be carefully guarded in expression. When there is high fever and exhaustion, indicative of a general in- fection, death may follow. In very serious cases pal- pebral gangrene may develop as an unpleasant com- plication (vide, p. 11). It is to be remembered that in convalescent cases sudden relapses are not infrequent. The disease con- fers no immunity; on the contrary, one attack predis- poses to another. Therapy is local in character and consists in the application of unguents which render the tense skin more supple and also have an excellent subjective effect. Neutral unguents (boracic acid, resorcin, etc.) are best. Others prefer cold applications (wet cloths). Where there is menacing tension of the lids and ex- treme pain, scarification of the skin may be considered as a last resort (vide Gangrene, p. 11). General treatment, i. e., rest in bed, fever-diet, etc., needs no discussion. Erysipelas is extremely infectious, and requires, therefore, the most perfect isolation possible. Edema of tlie eyelids is not, commonly, a nosologic entity. As we have already remarked, the derm of the lid is not intimately bound to the subjacent tissues, so that fluid exudates find abundant space beneath the palpe- bral skin and, therefore, are often apt to extend to a considerable distance. This is best seen in palpebral hemorrhage {vide Fig. 2). Inflammatory edemas may often arise from slight irritations (e. g., bee-stings, fly-bites) and spread un- til the lids appear like bags distended with water, the eye being completely occluded. Palpebral edemas, 2 then, are mostly secondary phenomena, and are also noted in cases of abscess, chalazion, hordeolum, dacro- cystitis, orbital phlegmon, panophthalmia, etc. Furthermore, it is well-known that anasarca, with simultaneous swelling of the ankle, is also apt to de- velop palpebral edema (renal disease). A doughy edema of the lids is found in trichinosis, the trichina? having a predilection for the orbital muscle. Haemorrhagia Subdermalis et Subconjunctivalis Plate U., Fig. 2. Palpebral sugillation or suffusion, i. e., haemorrhagia subdermalis, is a very striking phenomenon. Because of the spongy tissue beneath the skin, the blood ex- tends easily and far. The red tint soon changes to a reddish-blue and then becomes blue-black (the well- known black eye resulting from a blow). The hem- orrhage is, commonly, sharply limited at the orbital margin, for here the skin is firmly attached to the bone by tense connective tissue. The skin about the root of the nose is, on the contrary, loosely bound to the subjacent tissue. Hence, the hemorrhage beneath the sMn of one eye may extend under the skin of the nasal bridge and appear, with correspondent colora- tion, beneath the sMn of the uninjured optic. It fre- quently happens that, after operation on one eye, hem- orrhagic discoloration develops in both. In such cases one should not be misled to the conclusion that both eyes had suffered injury. Sugillation of the lids is particularly a sequela of trauma, notably that due to blows with blunt objects (fist, club, etc.); also of major operations, such as enucleation, where the wound is deep, whilst in cuts of palpebral tissue it is rarely observed, for the blood has abundant exit. Spontaneous bleeding may also occur, for the vas- cular channels, from lack of supporting tissue, are 4 Fig. 2. Haemorrhagia subdermalis et subconjunctivalis. ?ebman Company, New York. easily ruptured, as during violent exertion, by crush- ing, sneezing, coughing, etc. Palpebral sugillation is of special significance in diagnosing fracture of the base of the skull. In this grave injury the blood often travels from the seat of fracture forwards along the floor of the orbit, appear- ing, usually after some lapse of time, beneath the con- junctiva {vide infra) and the skin of the lower lid, particularly in the region of the inner canthus. The discolored skin permits instant diagnosis, and only the cause of the hemorrhage demands further investigation. The prognosis is commonly favorable. The dis- coloration gradually takes on a greenish hue, and in most cases the blood is resorbed after a few weeks. Rarely, the effusion passes into suppuration, thus forming a palpebral abscess. Therapy. Cool applications. Subconjunctival hemorrhage develops even more easily, for here, likewise, there is very loose attach- ment to underlying tissues, and we have: haemor- rhagia suhconjunctivalis, hyphaema conjunctivae or, briefly, hyposphagma. In youth it almost invariably accompanies pertussis and may also be caused by immoderate coughing, pressure or strangling in children. In older individ- uals it is indicative of vascular fragility, of arterio- sclerosis, and often accompanies contracted kidney. Conjunctival hemorrhages have, therefore, weighty symptomatic significance. The diagnosis is not difficult : the uniform, super- ficial reddening, if once seen, will not be confused with an inflammation of the conjunctiva, where the indi- vidual dilated blood-vessels are easily distinguished. 5 Local therapy is of little value. The striking phenomenon of a subconjunctival hemorrhage usually terrifies the patient or those about him, but they may Be easily calmed, for the eye is never damaged. How- ever, lead-water or cold compresses should be applied. The constitutional cause of the hemorrhage is to be sought and treated. The phenomenon is frequently a prodrome of cerebral apoplexy. cff, Atlas. Tab. Ill Fig. 3. Morbilli. Blepharo-Conjunctivitis exanthematica. LibiiKiii Company. New York. Morbilli— Conjunctivitis Exanthematica. Plate III., Fig. 3. With the efflorescence of the exanthem in the various acute general infections, but notably so in measles, characteristic catarrhal phenomena commonly appear in the form of more or less violent conjunctivitis and blepharitis with redness, photophobia, and secretion, as well as catarrhal conditions in the nose and upper air-passages. These catarrhal conditions may even precede the exanthematous efflorescence by some days, the secretion consisting either of increased lacrimal fluid or, not rarely, of a mucous or purulent exudate drying into scales and crusts along the margin of the lid {vide Fig. 3). Croupous membranes seldom de- velop. Prog'nosis. In measles the acute conjunctival catarrh always present is not to be slighted Though spontaneously disappearing, in most cases, after 2-3 weeks, it may, if neglected, lead to a redness and sen- sitivity of the blepharo-conjunctival tissues, annoying the patient for years or during his entire life. Serious comi^lications such as a blennorrhoic or diphtheritic conjunctivitis or corneal infiltration or a secondary iritis are not impossible. Tlierapy. As with measles in general, cleanli- ness plays a chief role in the ophthalmic treatment. The lids are to be bathed carefully with lukewarm 7 boracic water and the dried exudate softened and re- moved. In most eases, this will suffice. Where lacri- mation is more abundant, one drop of a slightly as- tringent collyrium (acid, tannicum i%, resorcin i%, zinc sulfate Vifo) may be used daily. With purulent secretion or the formation of membrane, irrigation with a Vio or V*^" solution of silver nitrate is indicated. Where such conditions develop, the globe should be closely watched for pericorneal injection (atropin) or corneal infiltration. The room is to be kept moderately darkened and the child not exposed to ordinary light until all oph- thalmic irritation has subsided. irccff, Atl;is. Tab. IV. Fig. 4. I'ustula maligna — Anthrax. nan Coinpaiiy, New York. Pustula Maligna— Anthrax. Plate IV., Fig. 4. The anthrax pustule or pustula maligna not infre- quently appears upon the eyelid. Man is inoculated with the bacillus anthracis from diseased animals by wiping, rubbing or scratching the eyes with the hand, and malignant pustule is therefore found in individ- uals handling animal products — cattle dealers, butchers, tanners, dealers in leather or furs. The affection often begins with a vesicle on the margin of the lid filled with yellow turbid or bloody matter. There is also a violent inflammatory edema of the lid and tense infiltration of the skin. Soon swelling of the preauricular and submaxillary glands and fever de- velop, followed by rupture of the pustule which be- comes covered by a scab. The surroimding skin then turns a grayish color, indicative of commencing ne- crosis. Diag'nosis. Similar vesicular formation may also be found in phlegmonous inflammations, carbun- cle, and in glanders. Bacteriologic discovery of the specific bacilli (non-mobile rods with square-cut ends, often in long chains) renders the diagnosis certain. The prog'nosis is extremely bad, for the lids usually become necrosed, and the case terminates in death. Formerly, the tlierapy was surgical: incision, currettage, or a Paquelin cauterization. We have learned, however, that the less the site of infection is 9 disturbed, the less danger there is of bacterial en- trance into the blood stream. Bearing this in mind, the best treatment is the application of unguents or aseptic compresses. The scabs and necrotic tissues are left for gradual and spontaneous desquamation. If the infection do not terminate fatally, plastic sur- gery is indicated. Fig. 4 shows a malignant pustule of the lid, whose reproduction in this atlas was kindly permitted by Prof. Dr. Bockenheimer. The case is one of external anthrax infection in a laborer employed in a tannery, and developed from a slight scratch in the skin of the cheek. At first, a red nodule appeared, then several vesicles filled with a yellow Quid of bacillary content. There was widespread carbunculoid infiltration, marked edema of the lids and an erysipelatoid redden- ing of the entire cheek. Soon after rupture of the vesicle a scab formed at the site of infection, with an areola of grayish skin gradually passing into necro- sis. The process, with marked systemic involvement, fever, chills, delirium, then extended to the eyelids, which, because of the enormous tumefaction, could no longer be opened even by force. Pustule after pustule developed, with correspondent gangrene of the skin after their rupture. The entire half of the face was protected by an unguental application. 10 ff, Atlas. lab. V. Fig. 5. Gangraena palpebrarum— Anthrax. 1 Company. New York . Gangraena Palpebrarum. Anthrax. Plate V., Fia. 5. The delicate texture of the palpebral skin, its thin corium, the loose subcutaneous tissues with their large lymph spaces and the richness of the vascular supply, permit easy extension of a malignant inflammation and trophic disturbance of tissue. We are speaking of gangrene when the breaking-down of tissue ele- ments occurs with decomposition and putrefaction. In such case, we find in the palpebral region a circum- scribed, fetid necrosis surrounded by a zone of in- flammatory reaction. According to Romer, to whom we are indebted for a study of the subject, gangrene may develop endo- geously, i. e., by metastasis, or ectogenously, i. e., from some local disturbance. I. The Endogenous Form. Metastatic gangrene of the lids develops, but not often, in severe general dis- eases, particularly typhoid, measles, scarlatina. Even in 1794, Himly reported that in grave typhoid the eye- lids became blue and sphacelated within a few hours. Fieuzal gives three cases of palpebral gangrene dur- ing measles, and similar cases are recorded by Knies and Eandall. Partial gangrene of the eyelid in scarlatina is de- scribed by St. Martin and Jackson, whilst numerous palpebral abscesses have been observed in influenza. In pyemia and sepsis, gangrene of the lid is caused 11 by infectious emboli, and it has also been attributed to diabetes and alcoholism. II. The Ectogenous Form. Here the necrosis may proceed from foci of inflammation in the neighborhood of the eye, or develop primarily in the palpebral tissue. Secondary necroses of the lid are observed most frequently as complications of facial erysipelas. The minutest infected wound often plays a role here, and more extensive injuries are not rarely etiologic. Schmidt-Eimpler reports a case where, after a blow from a twig upon the malar bone, timiefaction of the eyelid developed, and five days later the palpebral tis- sue was transformed into an ulcer full of necrotic shreds. Among the primary affections of the lid where gan- grene is possible, anthrax is pre-eminent. In Gross- mann's case, we are, doubtless, dealing with pustula maligna. In a broom-maker a pustule as large as a pea developed, with high fever, on the skin of the upi^er eyelid, whence a brawny edema spread, reach- ing even to the thorax. By the third day the skin of the entire lid had become transformed into a black crust. Cure followed, but with extreme ectropion. For therapy consult page 9. In Fig. 5, we have the case of Prof. Bockenheimer some weeks after the infection. The extensive dermal gangrene, cognizable by the black discoloration and leathern consistency, is already delimited by a zone of pus and iinctuous granulation tissue from the ad- jacent non-gangrenous skin which, however, is slightly reddened and gives evidence of inflammatory infiltra- tion. But the necrosis is still firmly attached to the subjacent tissue. Its forcible removal by the knife or a clumsy extirpation would result only in renascence of the infection. Gradual desquamation was, there- 12 fore, attained by compresses wet with hydrogen per- oxid and boric acid solution and by applications of ointments. In this ease, after the loosening of ne- crotic tissues and subsidence of inflammatory pro- cesses in the circumjacent skin, the somewhat marked defect caused by the loss of the entire upper lid was plastically corrected by a pediculated flap of skin from the surrounding healthy tissue. Despite the unfavor- able prognosis in facial anthrax and the severity of the local process, the case was cured. 13 Herpes Facialis. Plate VI., Fig. 6; Plate VII., Figs. 7-8. Herpes zo.ster is an exanthematous disease of tlie skin, simulating an infection. In the territory sup- plied by some particulate nerve a vesicular eruption occurs with febrile phenomena and general weakness. The number of vesicles is extremely variable in differ- ent cases. Sirring and autumn are the seasons of elec- tion. The vesicle contains at first a clear watery fluid which soon becomes turbid and purulent. It then rup- tures and the resulting ulcus crusts over. After the ulcers heal, permanent scars remain, and as a rule, the individual is thenceforth immune. Of the cranial nerves the trigeminus in all its branches is most often affected and we have a herpes zoster ophthalmicus, usually along the course of the first branch of the nerve. In such case the vesicles are found on the upper lid, the forehead to the hairy margin of the scalp, and on the nose, although, be- cause of the almost invariable onesidedness of the affection, they are plainly delimited by the median line of the face (vide Plate VII., Fig. 7). In Fig. 8, Plate VIII., there are uncompionly numerous, ruptured vesicles covered with crusts which penetrate deeply into the corium. This latter case is borrowed from Jacobi's Atlas of Skin Diseases. If the 2nd branch of the trigeminus is affected, the vesicles are located upon the lower lid in the superior maxillary or malar region (Fig. 6, Plate VI). 14 ff. Alias Tal). VI. Fig. 6. Herpes facialis nan Company, New York. Qrceff. Athis, TO 6/3 O N a X TO en O N Rebman Conipanv, New York Not infrequently the skin disease is accompanied by an eruption of vesicles on the cornea, a grave compli- cation. Herpes zoster ophthalmicus is due to an inflamma- tory involvement of the trigeminus, either of the Gasserian ganglion, of the ciliary ganglion or of the nerve in its peripheral course. Diag'nosis of herpes zoster ophthalmicus is easy because of the distribution of the vesicles within a cer- tain neural territory, the one-sidedness, and the syn- chronous febrile development. It is differentiated from simple herpes febrilis (labialis) by the size of the vesicles. In simple herpes the epiderm only is vesiculated whilst in herpes zoster the ulcer sinks deep into the substance of the corium and a cicatrix remains after recovery. Prog-nosis is positively favorable. The scars left may later cause some annoyance. Therapy. Internally, salicyl preparations are called for; for neuralgic pains, quinine, antipyrin or phenacetin. The affected areas are best powdered with rice-starch, lycopodium, etc., which dry up the vesicles. When crusted over, the ulcerated surface heals. 15 Variola Vaccina. Plate VIII., Figs. 9-10. Vaccinal ophthalmia develops from infection of the eye with the lymph, generally by direct transmission by the finger from the vaccination into the optic; but also from dried lymph on bandages or the handker- chief. On the eyelids the eruption is usually found along the intermarginal portions. From small, superficial vesicles there develop, with marked inflammatory symptoms, chemosis, palpebral edema, and large, flat ulcers of a diphtheritic appearance. After 8 to 12 days healing begins with complete restitutio ad inte- grum in 2 to 3 weeks. The extreme brevity of the incubation stadium may in many cases be reduced to 3 to 4 days. The variola may also be localized upon the con- junctiva or the cornea. The diagnosis of vaccinal infection of the eye can offer little real difficulty, if we consider the mor- bidity (Schirmer). Differentiation from variola vera, where the pustules cover the entire surface of the body and grave constitutional symptoms are present, is easy. The ulcus durum (chancre) does not, as a rule, cause such marked inflammatory phenomena in the re- gion affected. Confusion with diphtheritic conditions is possible, but in the rarer diphtheritic ulceration on the margin 16 reeff. Atlas. Tab. Vlll. Fig. 9. Variola vaccina Fig. 10. Variola vaccina ;ebnian Company, New York of the lid, the whitish membrane covering the conjunc- tiva is seldom lacking; furthermore, in the vaccinal ulceration removal of the membrane leaves a clear red base whilst in diphtheria the base of the ulceration is dirty. Tlierapy. Treatment should be as unobtrusive as possible : the eye should be kept clean and the ulcer covered with some unguent. Cauterizing applications are dangerous. Keratitis profunda or an ulcus cornefe will develop severe complications, and treatment should be that adapted to these affections. Prophylactically, the family should be warned that the vaccinal virus may be transmitted to the eye by rubbing, etc. 17 Ulcus Durum. Plate IX., Pig. 11. The margin of the eyelid is not rarely the seat of primary infection, usually due to kissing or to trans- mission by the finger. The indurations seldom de- velop on the outer sMn but are almost invariably intermarginal or in the canthi or upon the conjunctiva tarsi. The reason therefor is plain. The cutis of the lid is not especially permeable, but the delicate tex- tures of the canthi where denn changes to mucosa, where the glands of the ciliary follicles and the Mei- bomian glands exude their contents offer facile inoc- ulation of the virus. The pre-auricular and other glands are often so swollen that a diagnosis of mumps might be possible. The affection begins with a swelling at whose apex a slight excoriation increasing in depth develops, so that finally an ulcer (rarely deep) with well-defined, indurated margins is present. Diagnosis of the extragenital sclerosis in the early stadia is extremely difficult, yet error would be fateful where the lesion is facial, particularly if on the eye or the organs protecting it, because of later possible diminution in function. In differentiation from similar morbid sjTidromes : hordeolum, cha- lazion, vaccine pustule, lupus, tuberculosis, diphtheria, chancroid and giunma, the most dependable pathog- nomic indication is the frequently marked, but indo lent, swelling of neighboring glands, in particulate, the 18 ceff, Atlas Tab. IX Fig. 11. Ulcus durum palpebrae. Syphilite. Primary affection. ?ebrnan Company, New York. pre-auricular glands. Not rarely, however, only the appearance of secondary phenomena and the result of mercurial treatment permit a decision. Kowalewski was the first to render a diagnosis by demonstrating the spirochaeta pallida in a palpebral ulcer. Therapy consists in local cleanliness by irriga- tion with weak antiseptic solutions followed by the application of some indifferent salve. Dusting with iodoform may greatly augment the inflammation with- out other benefit. The diagnosis once certain, there is no reason for delaying the constitutional treatment. 19 Xanthelasma. Plate X., Fig. 12. Xanthelasma is a flat, straw- or sulfur-colored tu- mor located in the palpebral skin, and generally mul- tiple in both upper and lower lid in the region of the inner canthus. Often a tendency is noted to develop symmetric figures on the two eyes. These tumors are found only in elderly adults and more often in women past the menopause. They grow very slowly and in- jure only cosmetically. When extirpated they rarely return. Dermatologists differentiate a X. planum and a X. tuberosima, the first of which is found only upon the Uds. Anatomically they are composed of the so-called xanthoma-cells (Touton), i. e. hypertrophied connec- tive tissue cells, lying in nests and filled with fat-drop- lets. These nests are separated from one another by walls of connective tissue. Giant-cells are not infre- quently found in them. Therapy is entirely cosmetic and consists of easily executed removal. Prognosis. The tumors are absolutely benign, causing only disfiguration. 20 [. Atliis Tab. X. Fig. 12. Xanthelasma. Company, New York . Atlns. I'lib. XI, o .

By atheroma (Griitzbeutel) is meant a retention- cyst, developing from sebaceous glands and hair fol- licles, and containing a gritty, whitish mass of comi- fied, degenerate epithelial cells, fat-droplets and cholesterin. The cyst walls are thin, as a rule, and composed of connective tissue. Atheromata develop usually in middle age on the hairy scalp or the genitalia. Not infrequently they are found on the margin of the eyelid, sometimes mul- tiple, and originating in the ciliary hair follicles (glands of Zeiss). The cysts arising from occluded sebaceous glands of the palpebral margin, the so- called glands of Moll, develop only as small translu- cent blebs the size of a pea or cherry. Diag'nosis is easily established from the loca- tion, painlessness and form and is rendered certain by the contents of the cyst. In the same location there may also be found congenital dermoid tumors lying beneath the skin of the lid, usually in the upper lid in either canthus. These push into the orbit but, as a rule, so superficially that the globe is not displaced. Beneath the skin they may be palpated as easily mov- able tumors the size of a bean. Therapy is surgical, but the extirpation must be thorough, for otherwise they are apt to develop again. 21 Molluscum Contagiosum. Plate XI., Fig. 14. Molluscum contagiosum (Cf. Epithelioma) is a growth composed of elevations, generally hempseed in size, rarely as large as peas, yellowish-white in color and occasionally of the hue of mother-of-pearl, cen- trally depressed. From this depression or crater, a gritty matter may be squeezed. These growths occur anywhere on the skin but are most conmion on the genitals and the eyelids, and close observation will de- tect them in the latter location oftener than is sup- posed — usually multiple on the lid margins. The tumor is contagious and hence, in persons of uncleanly habits, apt to take on multiple form. If such a growth exist on the margin of the upper lid, it is not long before one develops on the lower lid at the point of contact. A blind individual whom I saw had many hundred moUusca. Retzius was the first to demonstrate their conta- giousness by successful inoculation. The contents expressed from the nodule contain, histologically, cornified epithelia and numerous oval, very refractive, sharply defined bodies, the so-called molluscum corpuscles, — easily seen in sections of the extirpated tmnor. Virchow, Caspary and Lasser con- sider them bladder-like formations due to an altera- tion of cell-protoplasm. According to Bollinger, they are unicellular parasites, gregarinae, whilst Neisser considers them epithelial cells filled with gregarinae. Croker takes them to be similar to the oviform cocci- 22 dimn described by Leukhardt. Recently the growth has been carefully studied by Muetze under the direc- tion of Uhthoff and Axenfeld and, according to him, all of the transitions from normal epithelia to the mol- luscal corpuscles are observable. The latter, then, are to be considered as degenerate epithelial cells and not as protozoic. What the contagium is, we do not know. The dlag-nosis is easily gained from the form of the tumor with the central depression or crater, from which a core may be expressed in which, microscop- ically, the molluscal corpuscles are demonstrable. Therapy. Expression of the contents seldom suffices. It is best to remove the nodules with scissors. 23 Hordeolum. Plate XH., Fig. 15. Hordeolum or sty (Gerstenkorn) is the name given a small inflammatory swelling on the free outer mar- gin of the lid, due to suppuration of sebaceous glands and is merely, in other parts of the body, the derma- tologic acne vulgaris, simplex or pustulacea. The se- baceous glands of the free palpebral margin corre- spond to the hair follicles of the eyelashes and lead to them. Anatomically, they are here called the glands of Zeiss. The sty, however, is differentiated from ordinary acne by the fact that, although a harmless affection, it causes many more symptoms and more inconvenience and pain than acne, — due to the anatomic structure of its site. Usually the first symptom of the coining hordeolimi is a diffuse swelling and redness of the whole lid with a sensation of tension soon becoming painful. Exam- ination of the lid commonly discloses a small inflamed nodule on the free margin between or in front of the eyelashes, hard and extremely sensitive to the touch. Extension of the infiltration from the glands into ad- jacent tissues enlarges the nodule which may become the size of a pea or larger. As a rule, the palpebral skin is very red, the lid swollen and there is consid- erable pain so that the slight local affection may be- come very annoying. After a few days the centre of the infiltration develops a yellow point of suppuration which soon breaks externally on the palpebral mar- 24 Alias. Tab. Xll. Fig. 15. Hordeolum ioilip.lny. New York gin; the pus flows out and there is healing within a few days. More rarely the infiltration extends further into the palpebral tissues and develops severe in- flammation somewhat like a furimcle. In such cases the inflammatory phenomena may be quite violent and we have chemosis and marked infiltration of the pal- pebral and bulbar conjunctivae as well as tmnefaction of the Ud. The course is always rapid and favorable. Later, only close observation detects the slight scar left by the preceding disorder. Dlag'nosis at first is not always easy, for the vio- lent onset, the considerable and rapid swelling and the pains might presuppose some grave affection of the eye. A sty is to be suspected as soon as it is ascer- tained that the cornea is clear, the pericorneal tissue not injected, and the conjunctival sac free from ab- normal secretions, thereby excluding a commencing blenorrhea as well as a deeper-seated morbidity (pan- ophthalmia). It will not be long before a small in- flamed nodule will be found near the palpebral margin, rendering the diagnosis certain. If the finger be gent- ly passed over the surface of the lid, it often locates the swollen, painful spot. The hordeolum generally occurs in youth, from 12 to 25 years, seldom after this period. Its genesis is favored by an often insignificant chronic blepharitis, which has given the micro-organisms (sometimes hyphomycetic) always present and abundant on the palpebral margin opportunity to multiply enormously, penetrating and occluding the excretory ducts of the hair follicles. The stasis of their secretion together with bacterial activity soon develops suppuration. Therapy. When the process is incipient an at- tempt may be made to scatter the infiltration by warm 25 compresses before the glands develop suppuration. This is rarely successful, yet the warm applications are commendable, for they lessen the tension and swelling of the lids, diminish the pain, and aid and accelerate the breaking through the skin of the pus. Warm or hot cotton compresses dipped into a 2-4% boric acid solution are well borne by the eye, usually afford much relief and are much better than the or- dinary applications of chamomile tea or lead-water which often contain impurities or throw down a pre- cipitate. The compress is applied several times dur- ing the day for a quarter or half hour. If the patient remain in the house it is advisable to wear contin- uously a warm moist compress protected by rubber tissue, which will keep it moist 6 to 12 hours. At night this may be renewed and a bandage applied to hold it in place. If spontaneous rupture occur, the cavity should be well emptied, applying, if necessary, pressure with the finger, after which the slight wound soon heals. If the rupture delay too long and the pa- tient desires freedom from the annoying pain, a small cut with a lancet point may be made perpendicular to the focus of infiltration on the margin of the lid and pus squeezed out, thus materially shortening the pro- cess. After evacuation the pains mostly vanish and the inflammation recedes rapidly. In such case the moist compress should be continued for another 24 hours. The task now before us is to combat the so frequent relapses or implication of other hair follicles. It should first be determined if there be a chronic ble- pharitis. This, naturally, demands treatment, and the patient should also be warned to avoid for some time such external harmful influences as impure air, to- bacco smoke, coal-dust, etc. Before retiring at night the eyes should be cleansed with a cloth wet with some 26 collyrium, e. g. lotio Knmmerfeld, or, a thin layer of white precipitate ointment may be applied to the lids. In obstinate cases, paint the palpebral margin once daily with a 1% solution of silver nitrate. 27 Chalazion. Plate XIH., Figs. 16-17. By chalazion or Meibomian cyst (Hagelkorn) is meant a circmnscribed swelling on the inner surface of the eyelid beneath the conjunctiva. Its starting- point is a Meibomian gland lying in the tarsus under the conjunctiva and hence the chalazion develops from the tarsus. The Meibomian glands are merely modi- fications of the sebaceous glands of the external skin to which they are similar in histologic structure. Hence, pathologic processes in both species are much alike. Chalazion is a chronic affection of the Meibo- mian glands, developing slowly with almost no in- flammatory symptoms, and possibly remaining un- changed for years. During a period of months a small nodule grows in the palpebral tissue, at first causing no trouble and hence noticed by the patient only after it has attained some size. The lid is not reddened and the skin remains normal. If the tumor be minute, so that nothing is observable on the outer surface of the lid, the finger discovers the small spheric growth beneath the skin which is movable over it. Since the chalazion always develops in the tarsal cartilage, it is always mobile with the cartilage, not upon it. In the course of time the growths may become as large as peas, cherry-pits or beans. They cause then a palpebral deformity, particularly when, as is often the case, there is multiple formation, and the shot-like nodules may be seen from afar protrud- 28 u o o nan Company, New York. ing outward beneath the skin. Even in this stadium inflammation of the lid or pain is absent. If the lid become ectropic, a condition often aggravated by the stiffness of the palpebral tissue, we note a more or less prominent yellow-brown or slate-gray fleck with a reddened areola in the conjunctiva projecting into the eye. This may finally break through the conjunctiva, after which a somewhat thick, slimy fluid exudes from time to time and the tumor decreases somewhat in size. Its major portion, however, composed of firmer granulation tissue, remains in its capsule imchanged. In the course of months or years even these masses may so shrink or resorb that the tumor disappears. The chalazion is usually noted in adults, seldom de- veloping in children. Generally, there are several on one lid, or, all the lids are deformed by these lumps. In the beginning they cause little trouble, but in the advanced stage are disfiguring and either by the de- velopment of inflammatory symptoms, or by mechan- ical hindrance to the movement of lid and eye greatly annoy their possessor. Chalazia develop mostly where there exists a slight but chronic conjimctivitis, leading to occlusion of the excretory ducts of the Meibomian glands and reten- tion of their secretions. The content of the gland then becomes thickened and harder and may change by deposition of calcareous salts into a hard, chalky mass (calcareous infarct of the Meibomian gland or lithiasis palpebralis). These are seen beneath the palpebral conjunctiva as small white or bright yellow spots. In fact, calcareous infarcts of the Meibomian glands are frequently prodromal of chalazia, and are usually noted in considerable number surrounding a chalazion beneath the conjunctiva of the same lid. These thick- ened masses of glandular secretion may exert an in- flammatory action upon the endothelium and adjacent 29 tissues, because of which these begin to proliferate and become infiltrated with small cells. With the progress of such infiltration, the mass develops into a dense granulation tissue in which, sometimes, even giant cells are found. The center of this granulation tumor, deprived of vascular supply, may finally disintegrate and pass into mucoid degeneration. A dense, tough capsule, foimed of the surrounding tarsal tissue under pressure, commonly develops about such a mass, and the chalazion, therefore, is composed of tough, dense granulation tissue enclosed in a fibrous connective tis- sue capsule. Recently it has been maintained by several authors that the chalazion is, as a rule, tuberculous in nature, a statement which has been further supported by the demonstration of numerous giant cells in its tissues. Many investigations, however, prove the fallacy of such assertion, at least in the majority of cases, and the benign clinical course scarcely bespeaks a tuber- culous process. Tlierapy. At the beginning and as long as the chalazia remain small, we may try to scatter them by external means, e. g., by rubbing an ung. potass, iod. into the conjunctival sac or by painting the external skin with tr. iod. If this have no effect, small, hard chalazia may be left undisturbed. If they grow or are already so large as to be disfigurative, operation is indicated. The query at once arises whether the incision shall be dermal or conjunctival. Although the protrusion is mostly outwards, the skin should never be incised. The natural opening is inward, toward the conjunctiva, and by this path the tumor-masses are most easily reached and there results minimal deformity from the operation. The operation is not so easy and simple as 30 it might seem, for a single incision does not suflSce and the removal of the tough tissue is essential and often diflScult. The first cut, therefore, should by no means be too small or superficial. Its direction should be parallel to the palpebral margin. As the operation is painful, we anesthetize by plac- ing in the conjunctival sac three or four times at min- ute intervals some drops of a 2-4% solution of cocain, or, better yet, by injecting with a Pravaz syringe a few drops subcutaneously at the site of the tumor. The ectropic lid is best fixed with a blepharostat, the conjunctiva is divided with the knife down to the cap- sule and we endeavor to dissect out with forcep and scissors the encapsulated node. This is not always easy for the capsule is apt to be firmly attached to the surrounding tissues. If it cannot be shelled out in its entirety, as much as possible is cut out with scissors and forcep and the remainder removed with the sharp curette. To avoid relapses and the formation of new cha- lazia, a chronic conjunctivitis present must be treated and cured. If white calcareous infarcts of the Mei- bomian glands are noted, so that a number of excre- tory ducts are occluded, the glands must be slit open by passing a cataract needle down through the con- junctiva until the calcareous mass is exposed, when the infarct mav be removed with a fine curette. 31 Blepharitis Marginalis. Plate XIII., Fig. 16; Pi^te III., Fig. 3; Plate XIV., Fig. 18; Plate XXVIII., Fig. 41; Plate XXIX., Fig. 42. The various affections of the palpebral margin which begin with symptoms of an inflammatory na- ture, we term blepharitis marginalis. They belong to the most common diseases of the eye seen by the general practician, particularly in the larger cities and among the poorer classes where the anemic and scro- fulous children compose a majority of such patients. The skin of the body becomes very thin and delicate on the eyelids and still more so as it approaches the margins so that here we have the most tenuous and sensitive derm of the whole body. For this reason, it is easily comprehended that in the most various dermal diseases, particularly if located on the face and extending therefrom, we often find the palpebral margin particularly inclined to sympathetic complica- tion. The various skin troubles appearing on the eye- lid and its mai-gin are not, as a rule, differentiable from the adjacent foci of disease and should receive similar treatment, in regard to which special works are to be consulted. There frequently appear, however, on the margin of the lid characteristic types of inflammation which here demand special consideration. Firstly, we should differentiate from true inflamma- tions of the palpebral margin, a hyperemia of the part, well-termed blepharitis vasomotoria. 32 Hyperemia marginalis. In many delicate-skinned individuals, and particularly in the blond, the marginal skin is so sensitive that it becomes very red from the least external stimulus or irritation. As soon as these patients enter an atmosphere of tobacco smoke or go out in windy weather or are exposed to a strong light, they develop the ugly "red eyelids" within a few hours or the next morning. The phe- nomenon not only disfigures, thus often spoiling the patient's enjoyment of some harmless pleasure, but is also accompanied by many inconveniences. The eyes itch and burn, forcing the patient to rub the margins of the lids, and furthermore there is a sensation of weight and heat in the eyes often extremely annoying when engaged in diflBcult work. Often it requires no external irritant to evoke the troublesome symptoms which may be caused by unusual bodily exertion, over- use of the eyes, emotional disturbances, etc. If we consider that in most individuals, excesses, a night's carouse, long exposure to impure air laden with to- bacco fumes are quite evident in the eyes the morning after, it is comprehensible how vexatious it is for most youthful patients with hypersensitive margins of the eyelids to go about after the least indiscretion with swimming, reddened eyes which seem to betray an over-indulgence in alcohol or a night spent in tears. Not infrequently the insignificant affection hinders them in business. In acute attacks, the margins of both lids are much reddened and if closely observed, there will be found in the redness a number of delicate, bright-red, deep- ly-injected blood-vessels. Coexistent there is often present a slight swelling of the lids and an injected palpebral conjunctiva. Scale formation on the mar- gin of the lid or at the roots of the lashes is usually lacking, but the lacrimal secretion is, as a rule, in- creased, so that the eye "swims in tears." 33 If the trouble has been of some duration, the acute attacks, at first often repeated, develop a chronic con- dition, i. e. the lids remain red and their margins be- come thickened and heavy. Many thick, distended blood-vessels are seen in the palpebral edge which passes from a red to a violet tint. The patient devel- ops great photophobia, and, because of the ocular trouble, have to be extremely careful of themselves. Even at some distance the ugly red margins are vis- ible. The affection, at first insignificant, is most persist- ent, and in many instances resists treatment for a long while. Therapy must be both general and local. It is most important to strengthen and harden the young, delicate, often anemic or scrofulous individuals in whom the trouble first begins. Although it is neces- sary to warn against excesses, over-exertion, late re- tiring, too long reading, exposure to impure air, it is equally essential to avoid coddling. On the contrary, these patients should be as much as possible in the fresh, open air, and, healthful exercise, cold affusions with vigorous massage, bathing out of doors will in time strengthen the organism and harden the sensi- tive skin. Tonics such as quinine, iron, etc., may be given internally. Locally, the parts should be kept clean, and cold compresses of some mild astringent, such as lead- water, very weak solution of tannic acid, water con- taining a few drops of eau de Cologne or ethyl alcohol are to be commended. Whatever the agent, care should be taken that the sensitive parts be not irritated too much, and strongly concentrated solutions are to be avoided. The eye-douche is very useful and should be employed once daily or every second day, a finely divided and not too forcible stream being directed for 3-6 minutes against the edges of the gently closed lids. 34 To the douche may be added any suitable astringent and hardening agent (eau de Cologne, alcohol, borax). Salves are best dispensed with, for the ordinary un- guents are much too irritant. If the skin of the lids shows a tendency to chap or crack, a very thin film of pure lanolin may be applied at night before retiring. In obstinate cases, the margin may be painted with a 1% solution of silver nitrate or 2-3 superficial appli- cation made of lapis mitigatus in substance. Of inflammations of the palpebral margin, we have two chief types for differentiation : 1. Blepharitis marginalis sicca, also called blepha- radenitis, seborrhea marginalis, blepharitis squamosa, is a condition of hypersecretion from inflammatory ir- ritation of the sebaceous glands of the palpebral mar- gin, and hence, more exactly, a seborrhea of the ciliary portion of the eyelid. The sebum soon dries and forms small scales lying between the eyelashes upon the skin of the lid. Recent investigations have dem- onstrated that these scales are not altogether the prod- uct of desiccatetd sebum and dead, cast-off epidermal squams, but that numerous hyphomycetes and their colonies found on the margin of the lid and in the ex- cretory ducts of the glands probably engender the dis- ease in most instances. The patient is usually di'iven to the physician be- cause of a continual itching and burning. If the mar- gin of the lid be superficially examined, little that is abnormal is observed, but on closer investigation, or if one rub the finger firmly across the eyelashes, tho numberless minute, whitish-gray scales lying upon the margin of the lid at the roots of the lashes will come into evidence. After such dry massage, the palpebral margin looks as if powdered with flour, and by such pulling and rubbing the lashes may be dusted off. Un- derneath the scales the margin of the lid is reddened 35 but not ulcerated. The cilia are loosely rooted and easily removed, but in recent cases grow in again as before. When the condition has been of longer dura- tion, the eyelashes are affected, lose their luster, be- come bent and twisted and finally fall out. Formation of crusts or scabs with a glueing together of the lash- es seldom occurs. In such case, the crusts are chiefly composed of the dried mucous secretions of the glands, and beneath them (in blepharitis sicca) there is no ulceration. In therapy it is to be well understood that no un- guent nor any other remedy is of the slightest value unless before each application all scales are removed and the lid margin most carefully cleansed. The scales are best disposed of by dropping a little pure olive oil upon the margin and rubbing it in between the lashes. After a few minutes the scales have become loosened and may be removed by rubbing with a piece of flannel and using ciliary forceps until the field is clear. Repetition of this process as soon as new scales are formed should not be neglected because of the slight, transitory swelling and redness of the lid mar- gin following its execution, nor is any harm done if some lashes fall out; when loosely rooted they come out sooner or later, growing again as soon as the mar- gin of the lid becomes healthy. After cleansing and drying the parts, a portion of salve the size of a pea is rubbed into the margin with a glass rod or the fin- ger. Since cleansing, in the first sittings, somewhat irritates the eye, it is best done once a day, before re- tiring. The salve remains upon the margin of the lid in a thin layer during the night, and is washed off in the morning with soap and water. Suitable oint- ments are a 1 to 2% img. Pagenstecheri (hydrarg. oxyd. rubr.) or ung. diach. Hebrae, best attenuated with equal 30 quantities of vaseline. Carefully treated, blepharitis sicca is not obstinate and soon heals, without sequelae. 2. Blepharitis eczematosa or blepharitis ulcerosa, scrophulosa, is, as its name indicates, an eczema of the palpebral margin, and, as in dermal eczema, exhibits the most varied types. The first three stadia develop rapidly, as a rule, or else are not distinctly observed as such; the fifth sta- dium begins in an eczema already in the process of healing, so that the physician is best acquainted with the fourth stadium, by far the commonest in most cases, the stadium of moist ulceration and crust-for- mation. Primarily we have a hyperemia and swelling of the lid margin, due to a serious saturation of tissues and leucoeytic emigration. The tumefaction usually develops in spots so that a number of small, dense red nodules, the size of a hempseed or pinhead are found on the margin (stadium papulosum). With an increasing serous infiltration, the epithe- litun of the derm is raised up here and there and cir- cumscribed collections of fluid form between the epi- thelium and the rete mucosum, vesicles filled with a clear watery fluid (stadium vesiculosum). Gradually the leucoeytic emigration augments until the contents of the vesicle become more and more tur- bid and finally purulent (stadium pustulosum). At last the pustules break and ulcers form, soon crusting over. Beneath the crusts the weeping ulcers persist unchanged (stadium madidans), and in this state the disease may continue for a long time, new vesicles and pustules forming in the neighborhood of the ulceration, so that the various stadia may be syn- chronously observed, the stadium madidans predom- inating. When finally the inflammatory phenomena subside, 37 the exudation and crust-formation lessens. The ulcers heal, and epithelial loss is no longer observed on the superficies of the denn, but, the skin retains for some time the inclination to develop inordinate quantities of epithelial cells which rapidly comify and are cast off. Hence, we find the affected areas covered with layers of scales, the stadium squamosum. As mentioned above, the physician is usually con- fronted with the matured eczema in the fourth sta- dium. The margin of the lid is markedly swollen, thickened, and covered with crusts, and not infre- quently vesicles and pustules are seen in the neighbor- hood of the crusts. The pustules are most commonly located about the cilia, and when they rupture the sin- gle cilium is observed rising up out of a deep, crater- like ulcer. The ulcers soon begin to exude, and thick crusts form, which, if removed, expose the deep, easily bleeding ulcus. If the disease remain untreated the lashes fall out and do not return. The angle of the lid-margin is eaten away so that a slight eversion re- sults. The loss of the cilia is due to the fact that their follicles have been destroyed by suppuration. Where this has not happened, the cilia grow again through the crusts and cicatrices, but pervertedly, so that the eye may suffer greatly from their abnormal positions (vide Plate XXII., Pig. 13). Almost invariably the remainder of the palpebral skin and the conjunctivae are affected, and commonly the eczema extends to the cheeks or nose. Eczema of the scalp as well as of the eyelids is often present. The nasal cavities should be watched most carefully, for in them analogous pro- cesses (eczema, purulent discharges, ozena) often de- velop. As the cause of the disease, we almost invariably find a general scrofulosis and tuberculosis. The in dividuals affected are usually frail, poorly nourished 38 children, exhibiting all the signs of scrofula (eczema, glandular swelling, a puffy, bloated appearance, thick lips, etc.) More rarely, local injurious influences (bad air, dust, occupation-noxae) or persistent conjunctival irritation from epiphora or other secretions may de- velop eczema and ulceration of the palpebral margins. The diag-nosls of blepharitis eczematosa is not difficult. The disease is differentiated from blepha- ritis sicca, which occasionally begins with crust-for- mation, chiefly by the fact that when the crusts are removed, the deep eczematous ulcers appear. The eczema might be confused with sycosis (Bartflechte) which sometimes locates on the margin of the eyelid, but in sycosis the large, exuding areas and ulcerations are absent. Furthermore, sycosis develops almost in- variably in adult males, whilst blepharitis eczematosa usually affects weakly children. The course of an untreated blepharitis eczematosa is extremely chronic. In its chronicity it passes into a stage where the epithelial layer of the skin becomes necrotic, the denuded areas covered with thick, solid, yellow-brown scabs, and in this state, the disease may persist for years. With long continuance of the affection, the eyes suf- fer in many ways, and there are a number of sequelae of chronic blepharitis which injure the visual organs to a greater or less degree, e. g. Chronic conjunctivitis, which may cause much trouble. Destruction of the cilia and the margin of the lid. The hair follicles and glands become implicated in the ulcerative process and are destroyed by suppuration. Finally, all of the lashes fall out or there remain only a few. The lid-margin breaks down, and instead of the normal rectangular form, its delicate edge be- 39 comes rounded off, so that some portions are shrimk- en, others hypertrophic and thick. Trichiasis. The few remaining cilia may be turned inward by cicatricial contraction and thus possibly abrade the cornea. Therapy should not only be local, but constitu- tional. The hygienic environments of the patient are to be improved, the delicate children properly nour- ished, moimtain or seashore prescribed when condi- tions permit, and every endeavor made to vanquish the existent scrofulosis. Internally, cod-liver oil, iron, iodine, etc., are indicated, and for the habitual obsti- pation often present, calomel should initiate the treat- ment. Above all, the rarely absent nasal complication must be cured, for as long as it is present an ap- parently healed eye will soon become diseased again. Of local measures, the first is a careful, daily re- moval of the crusts. This is accomplished by loosen- ing them with warm water, or still better, with olive oil, followed by rubbing or scratching them off with blunt forceps. Loose or slanting lashes should be ex- tracted with cilia forceps. One should not be fright- ened if the ulcers beneath the crusts bleed easily and reproduce the crusts. In the first days of treatment a light superficial brushing-over of the ulcer's base with the mitigated silver nitrate stick (lapis mitiga- tus) is often helpful. Unguental treatment is partic- ularly applicable in this disease, and, as in all eczemas, care must be taken not to use too irritant salves. The choice of the salve is not of so much consequence as its degree of concentration. In weeping eczema of the eyelid and margin, it is best to prepare a compress suggested by Hebra. The ointment is spread thick upon strips of boracic gauze and these applied shingle- fashion to the eye, i. e. one strip overlying the strip 40 below. In order not to annoy the patient too much, the eyes may be treated in alternation. The best un- guent is Hebra's diachylon salve; the white and red precipitate ointments are often used but it is wise to prescribe the latter in less strength than originally given by Pagenstecher. Schreiber, of Magdeburg, is very successful with a 14% ointment of silver nitrate. A 1% resorcin unguent is recommended where the eyes are hypersensitive. The bandage should first be changed once, later twice in the 24 hours, and it is im- portant to see that the unguent be freshly made and its base not rancid. This unguental treatment generally causes the ec- zema to pass from the stadium madidans into the sta- dium squamosum or desquamation, when it should be stopped, the affected areas of skin usually healing soon with the employment of a dusting powder. In particularly obstinate or chronic eczemas, a tar treatment after the unguental is often advisable. The affected areas are painted daily with pure tar or with equal parts of tar and olive oil. With needful patience on the part of patient and physician and some care in the use of salves, which are not equally well borne by all patients, it is possible to overcome the most obstinate forms of the disease. 41 Entropium. Plate XIV., Fig. 18; Plate XXII., Fig. 31. In entropium, the lid or its margin is turned in so that the free edge and the lashes no longer project outwards but lie directly against the eyeball, upon which the cilia rub with every movement of the lid, thus causing irritant and inflammatory phenomena, i. e. they act like foreign bodies upon the exterior en- velope of the globe. Palpebral entropium is differentiated from trichi- asis and distichiasis as follows : In trichiasis the lash- es are correctly placed but the margin of the lid bear- ing them rolls inward toward the globe whilst in dis- tichiasis, the margin lies normally but the cilia grow crookedly or too much in an inward direction so that they impinge upon the eyeball. Frequently, however, we find both conditions present: misplacements of margin and cilia. If in a case of marked entropium we look directly at the eye, the edge of the lid is scarcely visible and it is only when the lid is pulled outwards by the fingers that it unrolls, bringing the margin into view, and, when let go, it rolls in again and the margin vanishes. The entropium may involve the entire lid, or por- tions only may be turned inwards, a partial entropium. In case of the latter, the lower lid is chiefly affected in the middle and outer third; the upper lid mostly in the outer third. Both lids, the upper and the lower, are about equally subject to the disease. Various degrees of inversion may be differentiated. 42 Atlas, Tab. XIV. Fig. 18. Entropium Trichiasis following Conjunctivitis simple.^ chronica. Company, New York In the minimal degree the free edge of the lid is turned so far inward that the tips of the cilia impinge upon the eyeball, being so twisted that they lie nearly parallel to the lid margin and glide tangentially across the globe. If the lid margin is turned so far inward that the lashes rest directly upon the eyeball, they gradually assume a position the reverse of natural, i. e. they no longer- curl outward but are bent inward to correspond to the curve of the eyeball so that their tips are directed away frum the cornea toward the conjunctival fornix. In the maximal degree of inver- sion, the palpebral skin lies against the globe whilst the cilia penetrate deeply into the conjunctival fornix. Entropium always results in injury to the affected eye, chiefly caused by the internally directed cilia. The patient has the sensation of a foreign body in the eye, and soon there develop extreme laerimation, pho- sophobia, conjunctival and pericorneal injection. If the entropium persist for some time, the cornea, in particulate, suffers, and may be injured permanently. Because of the continual irritation, the corneal epi- thelia become indurated, thickened and cloudy, or, it may happen that the epithelia in divers areas are in- jured by the cilia, and if opportunely infected, a super- ficial ulcer of the cornea may develop. In old chronic cases, the cornea is generally covered with pannus-like opacities and indurations. Inversion of the lids is invariably the result of pre- vious definite diseases of the eye, and in most in- stances is due to contraction or shriveling of conjunc- tival scar-tissue. According to their etiology we dif- ferentiate two chief forms of entropium: 1. Entropium cicatriceura., where, by cicatricial con- traction of conjunctival tissues, the margin of the lid is drawn inwards, the scars being due, generally, to a long-lasting trachoma, to the so-called cicatricial tra- 43 choma {vide Plate XX., Fig. 31). Each trachoma granule heals cicatricially, whence, where many and recurrent granules have occupied the palpebral con- junctiva, the conjunctival tissue still left, does not sufiSce, because of the long, radiating scars extending chiefly in a horizontal direction, to cover without ten- sion, the entire inner surface of the lid. Consequently, the lid is constricted interiorly from above downwards, and the punctum mobile, the free margin of the lid, is forced to yield and roll inwards. In such cases, the cilia, impinging almost entirely upon the eyeball, are no longer normal, but develop as long, fine hairs or degenerate into short, thick stumps (trichiasis). The free angular margin of the lid is, generally, no longer present, having been rounded off or quite flattened out. In other cases the conjunctival scars causing the entropium were due to wounds or burns or cauteriza- tions. 2. Entropium spasticum. This follows spasmodic contraction of certain fibers in the musculus orbicu- laris. To elucidate the genesis of this form of inver- sion, we must consider briefly the structure and action of this muscle. The musculus orbicularis is a super- ficially extended muscle of the skin, divisible into two portions. The first or inner portion, lying within the lid itself, extends to the palpebral fissure ; which it encircles, and is, therefore, called the portio palpe- bralis. The second, or outer portion, extends peri- pherally from the first to the orbital edge and adjacent parts and, hence, is dubbed the portio orbitalis. As a rule only the palpebral portion governs the move- ments of the lid; the orbital portion merely draws to- gether the facial derm surrounding the eyes and, therefore, aids in firm closure of the lids. The fibres of the portio palpebralis have a double curve: 1. with a concave side toward the palpebral margin, and 2. 44 with a concave side toward the eyeball, corresponding to its curvature. A contraction in these muscle bun- dles would result in straightening out both curves (to- ward the concave side), thus first closing the lids and, secondly, pressing them against the eyeball. If now, from any cause, there develops an unequal or imbal- anced contraction in the fibers of the orbicularis, e. g. so that the fibers at the lid margin are contracted or spasmodically tense, whilst all other fibers remain lax, the palpebral fibers overcome the others and roll the margin inwards. To accomplish this, however, an- other factor is requisite, namely, that the palpebral derm be not tense but loose and flabby. Both of these conditions are often present in elderly individuals, for which reason, entropium spasticum is most commonly found in this class of patients (entropium spasticum senile), particularly where the eye has been kept closed for some time, as after cataract operations, when it oftener occurs and becomes a very troublesome complication. In like manner, the orbicularis fibers of the margin of the lid gain the ascendancy if their tension be not counterbalanced by a normal curvature of the eyeball, which, if lacking, almost invariably develops inver- sion of both lids. But, even after the retrogression of the bulbus into the orbit, often occurring in ema- ciated seniles, entropium may develop, and likewise after a shriveling and atrophy of the bulbus. From a spasmodic contraction of the orbicularis (blepharospasmus) found particularly in children, en- tropium may be engendered, and here the portio orbi- talis often acts so violently that the margins of the two lids are pressed against each other until finally one of them rolls inwards. This form of entropium spasticum in youthful patients affects the lower lid alone. Therapy. Entropium in old people due to the 45 pressure of a bandage commonly disappears when the bandage is removed, but, if for other reasons it is necessary to continue the compress, we may endeavor to hold the lid in its normal position by using adhes- ive plaster and collodium, the application beginning at the palpebral edge and extending downward over the cheek. If the lid be not kept in place by this method, ligation will be necessary. If the inversion be due to blepharospasmus, this should be treated and cured, after which the entro- pium disappears of itself. In entropium due to cicatricial contractures, it is first essential to remove carefully with cilia forceps all the eyelashes impinging upon the bulbus. A per- manent cure is attained only by operation. 46 Atlas. Fig. 19. Lupus vulgaris faciei. Narhenectropium. II Company. New York Ectropium. Plate XV., Fig. 19. By ectropium is meant an anomalous position of the Kds where they with their conjunctivae are no longer closely appUed to the bulbus but roll outwards, away from it. When this happens, a larger or smaller area of the conjunctiva may lie exposed to view. There are various degrees of eversion, from the slightest, where the palpebral margin does not quite touch the eyeball, to a degree where the whole lid is turned in- side out. One or both lids may be affected; most com- monly, however, only the lower. ' But, even with a minimal eversion, the condition is extremely troublesome, and commonly the ectropium with its sequelae soon develop a state of great irrita- tion in the eyeball. Then, with the separation of the lid margin from the globe, the lacrimal puncta are thrown outwards and no longer drain the lacus lacri- malis. The natural transit of the lacrimal fluid being thus interfered with, the tears trickle over the edge of the lid and down the cheeks, and we have epiphora. A further consequence of ectropium is the inflam- mation and hypertrophy of the conjunctiva thus ex- posed to external irritants — air, dust, etc. It tumefies, and the swelUng leads to yet greater eversion. Thus, both conditions alternately aggravate each other. A high degree of ectropium may finally develop grave consequences for the eye, since the cornea, not being adequately covered by closure of the lids, invites the development of a keratitis e lagophthalmo. 47 According to their etiology we differentiate several species of ectropium: 1. Ectropium paralyticum. After paralyses of the musculus orbicularis, e. g. as a complication of facial paralysis, there usually develops a slight eversion of the lower lid, explained as follows: The orbicularis whose fibers are paralyzed is no longer able to hold the lid accurately against the globe; hence, the lid, obeying the law of gravitation, sinks down and some- what away from the eyeball. Because of this mechan- ical genesis, it is clear that the lower lid alone will be affected. 2. Ectropium senile. This form is very similar to the one just described, both in genesis and appear- ance, except that here paralysis is not etiologic but rather the lax, senile skin and musculature of the lid which are no longer able to hold it firmly against the globe. The lid sinks somewhat down and outwards, and there develops a sulcus betwixt lid and globe in which the exposed conjunctiva may be seen. 3. Ectropium spasticum. Pound chiefly in children and youthful individuals suffering from an acute con- junctivitis with tumefaction, particularly when accom- panied by a blepharospasm. If, with such children we attempt a forcible opening of the eye, it happens that by a strong contraction of the orbital portion of the musculus orbicularis a sudden and spontaneous eversion of both lids occurs. This may also be excited by simple pressure on the lids without touching the eye. For the development of an ectropivmi spasticum a conjunctiva well tumefied and a spasmodic state of the musculus orbicularis, more marked in the portio orbitalis, are necessary. If such a suddenly developed eversion be not speedily corrected, the already swollen conjunctiva will be strangulated by the portio palpe- bralis of the orbicularis and marked edematous tume- 48 faction will ensue. This may lead to permanent ever- sion until the conjunctivitis has been cured. Ectro- pium spasticum is mostly found in children suffering from a scrofulous conjunctivitis, more rarely in cases of ophthalmia neonatorum. It usually affects both lids simultaneously, and may attain a high degree, so that the bulbus is completely hidden by the swollen, everted lids. Lesser degrees of ectropium may develop from sim- ple swelling of the conjunctiva, which becomes not only thicker but broader and, because of the sausage- like tumefaction of the palpebral edge, is pushed still further away from the globe (ectropium mechanicum). The eversion is accentuated when, from pinching or a spasmodic statte, there is contraction of the palpebral portion of the orbicular muscle. 4. Ectropium cicatriceum. The highest degree of eversion is caused by cicatricial contractures. This demands that a portion of the palpebral edge have been destroyed and replaced by scar tissue. Such conditions are peculiarly apt to develop after burns of the skin of the lid or wounds of the lid, operations upon the cheek, caries of the orbital edge, etc. The scar formed invariably draws the margin of the lid yet farther downwards until finally the entire red- dened and thickened conjunctiva of the lid is fully ex- posed outwards, and of the lid itself only the edge, now far removed from the globe, is visible. Tberapy. The earliest possible correction of the eversion is to be sought, for the portion of conjunc- tival tissue turned outwards is continually exposed to the air and the dangerous substances contained in air, and which excite violent irritation of the eye. With increase of the conjunctival swelling, the eversion aug- ments until finally a circulus vitiosus is developed. A treatment without surgical intervention is pos- 49 sible only in ectropium spasticmn. Here, in the be- ginning of the trouble, the everted lids may be re- placed without much diflSculty and, to avoid an ever- ready relapse, they should be kept in the correct posi- tion by strips of adhesive plaster or the use of a com- pression bandage. In obstinate cases, an extension cut of the external canthus is to be commended before the correction of the eversion, for the bleeding caused by the cut is very beneficial. After the lids are replaced, the inflamma- tion and swelling of the conjunctiva should be reduced. Other forms of eversion are corrected only by means of the ectropium operation. 50 A(l:is. T;ib. XVI. Fig. 20. Carcinoma epitheliale I. Ill Conip.iny. New York. Carcinoma Epitheliale Palpebrarum. Plate XVI., Fig. 20; Plate XVII., Fig. 21. Carcinoma is the commonest palpebral neoplasm. It usually occurs as a shallow ulcer, scarcely rising above the superficies and having but a slightly ele- vated wall-like periphery. Actual tumors are few in number. The flat, slowly extending new growth is often called "ulcus rodens," but anatomically it is a genuine cancer of the superficies. There are two points of election for the develop- ment of palpebral earcinomata, first the inner canthus where we have a junction of external skin and con- junctiva. It is well known that such dermo-mucosal blendings (the margin of the lips, anus, palpebral margin) are areas of predilection for carcinomatous genesis. The second point of election is the external derm of the eyelid. Carcinomata developing in the first mentioned area are usually more malignant and more rapidly and deeply destructive, whilst those de- veloping in the palpebral derm are mostly benign and therefore of the ulcus rodens type. As regards localization the left side of the face is more often affected than the right. It is also certain that the neoplasm is much commoner on the lower lid than the upper, and more apt to be found in the in- ternal canthus and, as first remarked by Valude, in the neighborhood of the lacrimal sac. Here the can- cerous process penetrates deeply and rapidly, destroy- ing the lacrimal sac, then eroding the lacrimal bone 51 and extending to the nasal cavity, or, the tumor mass pushes through the lacrimal duct into the nasal fossa. Fig. 20 on Plate XVI. shows one of these flat dermal cancers of the left upper lid about to pass over the bridge of the nose to the other side. The growth of a sxiperficial carcinoma on the eyelid may be extremely slow, sometimes covering a period of 20 or 30 years (Schulz-Zehden). Such was the case of an old woman in the Home for Incurables, of whom Dr. Schulz-Zehden (Berlin) kind- ly permitted a wax model to be made, shown in Plate XVII., Fig. 21. The cancer, extending from the margin of the lid, had existed for many years. It had excavated a deep hole in the left side of the face, and the eyelids, the skin of forehead and cheek and the bony margin of the orbits had entirely disap- peared. The deep-simken, shriveled eyeball, in which the cornea is distinctly seen, still remains. The pa- tient had invariably refused operation, keeping the eroded area covered with a moist cloth. Recently, death occurred, and when we consider the many years of its existence, the slow progress of the carcinoma- tous growth is truly remarkable. In other cases the nose and cheek are soon impli- cated and upon them the growth progresses by contin- uity. Occasionally, however, autopsy alone demon- strates how extensively the adjacent organs and cav- ities were involved. Often the lymph glands remain unaffected for a long period. Thiersch observed glandular involve- ment in two instances only; Winiwarter, in 26 cases, twice ; Mayeda in his series of 195 carcinomata of this type, found eight glandular involvements, a percent- age of 4.1. In general, it may be said that the superficial type does not develop carcinomatous processes in the glands nor metastasis to internal organs. 52 Fig. 21. Carcinoma epitheliale palpebrariini man Company. New York. Etiologieally, we need only remark that cancer in this region frequently arises from constant irritation or rubbing of warts ; also from small wounds, cauter- ization, removal of vesicles, nodules, etc., and possibly from lupus. The beginning of the trouble is well described by Unna: "Ulcus rodens commences as a rose- red or pearl-gray nodule the size of a mustard seed, rising a millimeter or less above the surrounding surface, with very slow peripheral extension and the develop- ment of a central depression. Thus, there are found areas, apparently but not actually cicatrized, of a gray-yellow or gray-red color, the size of a pea or cov- ering an area equal to that of a dime or quarter-dollar, sometimes oval in contour, flat and lying in the plane of the healthy skin or slightly depressed, and limited by a delicate, ridge-like margin of the color of mother- of-pearl, from which frequently arise minute nodular thickenings. Any general thickening of the derm or any peripheral inflammation is not cognizable. Even in this stadium of nodular development, slight trau- mata of various parts of the nodule, usually the central portion, result in desquamation of the stratum cor- neum, and a dark crust or scab, formed of bloody se- rum and a new stratum corneum, develops. Left to itself, this crust falls off, after which the affection has its original cicatrized appearance. Repeated desquamation of the stratum cornemn finally leads to permanent ulceration, and thus the second or ulcera- tive stadium begins." Therapy is operative, followed eventually by a plastic operation upon the lid. Recently, cures with the Finsen light have been ob- tained. For amelioration of pain, the ulcerated areas are covered with bandages spread with unguent. 53 Dacryocystitis. Plate XVIII., Figs. 22 and 23. Inflammation of the lacrimal sac seldom follows a lesion or infection of the conjunctiva but is often due to some ascending nasal affection, to stasis and de- composition of the lacrimal fluid above a stricture or to lesion of the adjacent bony structures. Most commonly as a result of stricture below, the mucosa of the lacrimal sac will produce abundant pus which flows backwards into the eye, thus presenting a well known phenomenon which may long continue without externally visible inflammatory symptoms of importance. The best name for the malady is, therefore, dacryo- cystitis chronica and not dacryocystoblennorrhea. If only the unfortunate term, blennorrhea of the eye- applied to the most heterogenous affections — could be dropped! Nowadays, we are accustomed to differen- tiate etiologically, and this should be done whenever possible. It is anything but conmiendable to Imnp together trachoma, gonococcal infection, pneumo- coccal infection, and pus in the lacrimal sac under the rubric of blennorrhea. The chronic lesion of the lacrimal sac often does not betray itself externally save that pus is frequently seen in the eye. If, however, pressure is made upon the lacrimal sac in the inner canthus where it is crossed by the ligamentum canthi internum, it will be seen suddenly, that quantities of thick -pus are exuding from the puncta lacrimalia. 54 eff, Atlas. Tab. XVIII. Fig. 22. Dacryo - Cystitis acuta Fig. 23. Dacryo-Cystitis witli Fistula. 1 Company, New York , The extreme virulence of this pus from the lacrimal sac was known long before bacteriologic investiga- tions were invented. It was known also that the intact eyeball might be long exposed to the regurgitant pus from the lacrimal sac without suffering noticeable in- jury, until some minute lesion of the cornea permitted its entrance. Then a white speck developed upon the injured superficies of the cornea, a bacterial coloniza- tion, from which an ulcus serpens had origin. In pus from the lacrimal sac, extremely virulent pneumococci are usually found, sometimes in almost pure culture. Such chronic lesion of the sac may also be tubercu- lous, tubercles or tuberculous ulcers developing in the walls of the cavity. It is likewise frequent in chronic trachoma, tracho- ma follicles being found in the sac walls. Therapy. This should, above all else, be directed against the often etiologic nasal lesion. To cure af- fections of the lacrimal sac and duct, the pus in the sac must be frequently evacuated by pressure with the finger. Then the superior or inferior punctum lacri- male must be slit or enlarged (with a Weber knife) and, after the introduction of an Anel syringe, irriga- tion, first with disinfectant and then with astringent solutions, should be practiced, the fluid running through the nose and into the mouth. If these injec- tions show that the ductus naso-lacrimalis is perme- able, but constricted in places, Bowman's sounds may be used in gradual dilatation. If the duct be completely obliterated or if the use of the sounds be ineffectual, the radical operation or removal of the sac is indicated. Congenital Lesions of the Lacrimal Sac. Not rarely, pus flows from the lacrimal sac a few days after birth. The source of the purulency is easily overlooked, and the diagnosis made of blennorrhea neonatorum, gonococcal in etiology. This condition is often seen in children with congenital lues, and the suppuration may be caused by a neighboring osseous lesion. An antisyphilitic medication often suffices for the cure of the trouble. But there may be merely a simple retention in the lacrimal canal, an occlusion in the direction of the nose, and no real blenorrhea, in which case a single forcible pressure upon the dilated sac may open the channel and cause the recurrent pus to disappear. Acute Dachyocystitis. The syndrome is quite different when, from any cause, the pus breaks through the wall of the sac, for then it quickly spreads through the loose adjacent tis- sues, the lids swell edematously and soon we have a simple, subcutaneous furuncle in the center of which lies the dilated lacrimal sac. A case of this sort is seen in Plate XVIII., Fig. 22, to which the name, acute dacryocystitis, is given (ana- tomically, it would be called a pericystitis or cystitis with rupture). Diag'nosis must establish where, in the often marked and extensive tumefaction which may attack both eyelid and cheek, the induration is located, which, if pressed upon, causes pain. It is noticeable that in the region of greatest swelling there is frequently a deep horizontal furrow above and below which are two turgid red elevations {vide Fig. 22). The furrow is caused by the ligamentum canthi internum originating in the inner canthus, passing over the lacrimal sac and inserted into the lacrimal bone. Therapy. Warning is given against the use of injections or of sounds during the stadium of inflam- 56 mation, the result of which would be extension of the infection elsewhwere. The lesion should be treated as a furuncle, using warm compresses and poultices and finally making a wide incision. If not dispersed, the pus at last breaks through the external skin and flows out {vide Plate XVIII., Fig. 23), after which the lesion usually heals. If the sup- puration still continue, it is commonly due to caries of the lacrimal bone. The wound must then be widely opened, curetted, and packed with iodoform gauze. After the healing up of all these processes, there may still remain fistulae of the lacrimal sac. 57 Normal Conjunctiva Palpebrarum. Plate XIX., Fig. 24. The conjunctiva forms a sac or bag slit open along the line of the palpebral fissure, at the margin of which it is transmuted, without demarcation, into ordinary skin. In the conjunctival sac three areas are distinguished, viz.: 1, the C. palpebrarum; 2, the du- plication or fold, C. fornicis; 3, the C. bulbi or scler*. The C. palpebrarum alone has the properties of true mucosal tissue, and hence we find that mucosal lesions, e. g., infections such as gonorrhea, diphtheria, etc. as well as follicular affections, develop only in the conjunctiva palpebrarum. The C. bulbi is epidermal in type, and, therefore, dermal lesions, e. g. eczema- tous, are directly bulbar in location. In Plate XIX., Fig. 24, is seen the conjunctiva tarsi of the upper lid after eversion. The mucosa is pale and smooth and beneath it, the glistening yellowish Meibomian glands are distinctly visible. 58 ircL'fl. Atlas liil). .\l Fig. 24. Conjunctiva. Normal Condition. Fig. 25. Conjunctivitis catarrhalis simplex. Rebniail Company, New York. Conjunctivitis Catarrhalis, Plate XIX., Fig. 25. The conjunctiva is a delicate, sensitive tissue, be- coming hyperemic and irritated from the least stimu- lus, e. g. exposure to air, inundation with water or the salty lacrimal secretion, entropium, etc. If the irritation continue for some time or augment, there develops an inflammation of the membrane, which may exhibit the form of an acute or chronic catarrh. The surface of the swollen and inflamed mucosa does not long remain smooth; elevations and wrinklings are soon in evidence and the conjunctiva presents the appearance of a piece of finely granulated leather or clipped velvet (a papillated appearance, vide Plate XIX., Fig. 25), actually due to wrinkles and furrows in the tumefied mucous membrane. If these irregularities increase in volume, become cockscomb-like, they are called papillary elevations, and are to be carefully differentiated from follicles {vide C. follicularis, infra). Acute conjunctivitis is mostly due to an infection, whence it may properly be termed, conjunctivitis in- fectiosa. It is capable of transmission and sometimes excites widespread acute epidemics {cf. in contrast, the behavior of trachoma, often confused with this affection). Recent baeteriologic investigation has taught us that there are several species of acute, in- fectious conjunctivitis, also differentiable clinically; e. g. conjunctivitis caused by the pneumococcus, the Morax-Axenfeld diplobacillus, the Koch- Weeks bacil- lus, streptococci, etc. 59 Chronic conjunctivitis is due either to external noxae (dust, smoke, wind, cold) acting upon hypersensitive membranes or is a sequela of acute infections. Therapy. Our treatment is directed towards dis- infection of the infected mucosa, and the lessening of secretion and the enormous dilatation of the blood- vessels by means of astringents. Where secretions are dammed up, micro-organisms multiply rapidly, and nothing is more senseless than prolonged bandaging of an eye endeavoring to rid itself of such products. On the contrary, we should seek by frequent changing of compresses and by irri- gation, to provide for unhindered secretion and its removal. Since the conjunctiva bears well both the action of cold and cauterizing agents, we choose cold solutions (water, lead-water, boric acid, sublimate 1:5000, etc.) in order to profit by the synchronous as- tringent effect of the low temperature. Medicaments may be instilled guttatim into the con- junctival sac, or, after eversion of the lid a thick brush dipped into the solution may be passed over the diseased area. The following drugs are commended: zinc sulfur, % to 1 or 2% ; zinc sozoiodol, 1/2 to 1% ; so- lution of alima 1% ; sod. sozoiodol, 3 to 6% ; resorcin, 1 to 2% ; acid, tannic, 1 to 2%. In purulent secretions, the sovereign remedy is silver nitrate, 1/5 to 1% or its substitutes (protargol, argentamin, albargin, etc.). 60 iff, Atlas. u '^ 'J5 C o man Company, New York Conjunctivitis Follicularis. Plate XX., Fig. 26. Another species of elevations on the conjunctiva palpebrariun is the follicular. The follicles at first resemble transparent vesicles ; later, and in malignant forms, they look like frog-spawn or cooked sago grains, and are composed of circumscribed aggrega- tions of round cells underneath the epithelium. They are, therefore, neoplasmic, comparable to lymph folli- cles or lymphomata, and develop in the conjunctiva from the most varied stimuli (chemical, thermic, bac- teriologic). On the other hand, it must be empha- sized that not every stimulus or irritation develops these follicles, nor are they due to the intensity or pro- longed action of the irritation but to its specificity. Simple chronic catarrh, however long its duration, never develops follicles; they are also absent in the most violent conjunctival inflammations we know, viz. gonococcal or diphtheritic infections. Contrarily, the formation of follicles is noted in a large number of conjunctival affections, plainly due not to infection alone, but also to other irritations. The various spe- cies of conjunctivitis may, therefore, be divided into those beginning with the development of follicles, and those where such formation is absent. A certain percentage of children with, conjunctival follicles are found in all schools, but the conjunctiva is pale in color and normal and the condition causes no trouble. In such cases, diagnosis of conjunctivitis fol- licularis is incorrect, for there is no conjunctivitis. 61 The chlorotic and anemic children have merely dilated lymph vessels in the conjunctival superficies, — lymph- ectasia. Follicles develop whenever numbers of indi- viduals are crowded together in a heavy, impure air, as in overfilled public schools, in schoolrooms espe- cially, in orphan asylums, etc. All inmates of peni- tentiaries and prisons show, post mortem, microscopic follicles in the conjunctiva. That in such cases symp- toms of conjunctival inflammation are usually absent, is due, in my opinion, to the fact that, as a rule, it is not a question here of infection, the phenomenon being due to the irritant atmosphere, some authorities attributing it to the ammoniacal vapors, others to the anthropotoxin present, etc. There are, however, plainly infectious but mild con- junctivites in which follicles appear, but, generally, not numerous, superficially located and chiefly iB the lower lid. These follicles disappear without leaving scars. Therapy. Sojourn in a pure atmosphere and ex- ercise in the open air often suffice. The follicles so often found in school children frequently disappear spontaneously during vacation. In addition, the eyes should be repeatedly washed, and compresses of 2-4% boracic acid solution or leadwater applied. For in- stillation, Forster's 2% solution of sod. biboracicum is best. 62 Fig. 28. Conjunctivitis trachomatosa Fig. 29. Sklerosing Traciioma. an Company, New York. Conjunctivitis Trachomatosa. Plate XX., Fig. 27; Plate XXI., Figs. 28-29. Trachoma is an infection locating in the mucosa of the lid, and is indubitably a specific morbid entity, whose cause we do not know with certainty. It is not communicable to animals, though possibly transmis- sible in mild form to the anthropomorphous apes. Trachoma is distinguished by the formation of large follicles which, accompanied by inflammation and marked papillary tumefaction, constantly increase in size and number and finally lead to necrosis and sub- epithelial shriveling. It is a world-wide disease, but its occurrence is not symmetric, i. e. in regions free of trachoma are found here and there larger or smaller areas in which cases of trachoma are always numerous, so-called "tra- choma islets." Is it possible to differentiate with certainty tracho- ma and follicular catarrh? In most cases, yes, though at first not always without error, though diagnosis may be invariably established by more extended ob- servation. In follicular catarrh, we have absolutely benign new- formations, usually with no adjacent in- flammation, no reaction, no tumefaction, and which do not lead to any notable swelling of fornices and papillae, and which, in contrast to trachoma, prefer- ably develop in a pale, anemic mucosa. Their lack of malignancy is shown by the fact that they never lead to destruction of mucosal tissue, but sooner or later disappear spontaneously, leaving no trace of their existence. 63 It is very different with the trachoma granule. It generally presents an entirely different appearance, for, whilst the follicular granule is clear and pale, more like a vesicle, the deeper-seated grannie of trachoma soon becomes gray and discolored. The circumjacent mucosa is deeply reddened, tumefied (so that the tra- choma granule seems to lie deeper below the surface) and the swollen fomices, when the lid is everted, roll out as if enlarged and thickened. Very soon there develop notable papillary proliferations, indicative of the violent reaction excited by the powerful \'irus — phenomena always absent in follicular catarrh. In its course, the malignant character of trachoma is made perfectly evident. The trachoma granule does not, after existing for some time, return to a norm, but is distinguished by its destructive action upon the mucous membrane. It tends notably toward a meta- morphosis of the mucosa into a tough, cicatricial tis- sue and develops a sort of cirrhosis, similar to that caused in lung, liver, kidney by certain inflammatory processes, and because of this we get the common se- quelae of trachoma. The cornea is often implicated and pannus develops. Trachoma is at the present time a pre-eminently chronic disease, endemic in many regions, absent in others. When endemic, it pursues its course, and, probably has for centuries; one patient after another is slowly infected, and, of a family of six, possibly three are trachomatous, and, gradually, after months or years, the others will be. The transmission is not easily accomplished, and continual, prolonged associ- ation with those infected, a common use of sleeping places, towels, etc., are requisite. If an individual is infected, it is often a long time before he notices the slightest sign of inflammation, and it may be months or years ere the process becomes malignant. Some- 64 times, however, the disease, in rare and isolated cases, runs a violent course. If a patient with bad trachoma enter some institution, he usually infects, after some months, a greater or less number of his comrades, and, in this manner there gradually develops a small en- demic. But, I have never found all the inmates of such an institution affected, which is proof that even from long and daily association infection need not follow. Trachoma, therefore, is always present in regions where it is indigenous; one individual after another is slowly infected, whilst other cases recover, so that the number of those diseased varies within certain limits; some years perhaps less, other years, greater. But, the report that a sudden outbreak of trachoma has occurred, has invariably been proven false. Either it was not trachoma, but rapidly spreading innocuous catarrh accompanied by tumefaction, or some other disease, or else in the regions where trachoma had ex- isted for years, attention has been suddenly fixed again upon the disease. As insidious and chronic as is the progress of tra- choma from patient to patient, so is its course, which if not interfered with, may extend over years or even a lifetime. Quite a number of cases finally recover. But even the best treatment must cover months, and be extremely energetic, if a sure and permanent cure is to be attained. Relapses are very frequent. The disease is one of the most malignant ophthalmic dis- eases known, and, in common with blenorrhea neona- torum influences largely the number of the blind. Still greater is the number of patients who, while not en- tirely blind, suffer greatly in later life from its se- quel*. What happens, finally, to the trachoma granule? After long duration, there develops always in its interior a sort of softening, and we find the large cells 65 in the stadium of necrosis, the nuclei no longer stain- ing, until at last there is left only a granular, crumbly mass in which the original elements have vanished. In many cases, the softening does not develop equally throughout the contents of the follicle but begins in foci, but commonly the central portion is most affected. The most typical illustration of the softened follicle is the clinical picture of the so-called gelatinous tra- choma (Stellwag). Here the follicular formations stand so closely together that the single, softened fol- licles merge into one jelly-like mass (Fig. 29). According to Ralilmann, Addario and others, the rupture of the follicle and exudation of its contents is the natural termination. In my opinion, the gradual resorption of the follicu- lar contents is by far the more frequent and natural process. This resorption is found, apparently, not only when the contents are softened, but according to clinical experience, in any stadium. Thus, we have seen minute follicles, where there can be no possible softening, gradually disappear in numerous instances when treated medicamentally, in which cases there was certainly no rupture and exudation of the con- tents.

Pannus Trachomatosus, Plate XXII., Pigs. 30, 31 ; Plate XXIII., Figs. 32, 33. The trachomatous process may pass from the con- junctiva palpebrarum et fornicis to the cornea with- out attacking the conjunctiva bulbi, and upon the cor- nea develop the pannus trachomatosus, starting al- most invariably at the corneal margin and usually from the upper portion. Here are seen at first, small, circumscribed elevations demonstrable only with a magnifying glass, — minute but distinct points rising above the corneal surface, sometimes attaining the size of a poppy-seed. These solid nodules, gray-white in color are follicles, circumscribed, subepithelial infil- trations of clearly defined masses of Ijmiphoid cells. If the nodules already lie in the transparent corneal tissue, many of them may be seen surrounded by slightly cloudy areola". Later, the nodules become confluent, forming a soft, diffuse mass, rich in cells, which, subepithelially, push forward from the superior margin of the cornea across its transparent tissues. Since tliis neoplasmic layer is not everywhere of equal thickness, the overlying epithelium is humped up here and there. As soon, however, as the layer has pro- gressed a millimeter or more across the transparent cornea, there begins, at its superior edge, a vascular proliferation extending with it across the cornea but always somewhat posterior to the zone of infiltration. These blood vessels do not all extend meridianly to- ward the center of the cornea, but are inclined rather to run in parallel from above downward. 67 According to the vascular development, the pannus varies in appearance. A fresh pannus, with few of these blood vessels extending downwards, is called pannus tenuis; if they are numerous, pannus vascu- losiis. Sometimes, the new tissue becomes so thick and vascular that it appears like granulation-tissue or raw flesh lying upon the cornea, and is then termed pannus crassus or carnosus; less suitably, pannus sar- comatosus. With retrogression of the growth, the zone of infec- tion first recedes and the blood vessels follow the vas- cularity, thus always remaining longer in evidence {vide Fig. 45). Because of this, the progressing and retrogressing panni are always easily differentiated. As soon as the pannus and the blood vessels have somewhat passed the central point of the cornea, the picture changes. The blood vessels no longer run parallel from above but extend in all directions on the corneal surface, in whose central portion they fre- quently anastomose and form varicose swellings {vide Fig. 46), and it is seen from their more indis- tinct, bluish hue, that they now lie, in many areas, deeper in the tissues. An old pannus, with connective tissue metamorphosis, has usually but few blood-ves- sels and these of diminished caliber: pannus siccus. Cicatricial Trachoma. Finally, and commonly after persisting for years, the trachoma leads to a more or less extensive cica- tricial contraction of the affected mucosa. The tarsus is, as a rule, implicated later. Its tissues, at first densely infiltrated, exhibit marked tumefaction, but, in time contract, and we have a rigid, sclerotic invo- lution (Plate XXni., Fig. 32). The tarsal distortion is typical in all cases, i. e. there is not equal curvature of the cartilage but a percep- 68 Tab. XXIII. CO ;i CO C o X ^:i n Company, New York, tible notch in its middle portion. It is easily cognized that the callous thickening of the conjunctiva is great- est at a point corresponding to this notch, so that here, in a fashion, the punctum fixum of the cicatricial re- traction is located, because of which the two cartilage margins are displaced by the retractive action of the scar. Hence, the distorted, trough-like cartilage is, because correspondent to the thickest portion of the callous conjunctival cicatrix, more or less indented. With the inward bending of the tarsus, the free margin of the lid is also bent inwards, and there de- velops entropium with its well known grave sequelae (Fig. 31). If, finally, the conjunctiva becomes so cicatrized, that the cornea is no longer sufficiently moistened, the entire surface of the eyeball becomes rough, dry, epi- dermoid, a condition called xerophthalmus (Plate XXIII., Fig. 33). The tberapy of trachoma. We have medical, me- chanical and surgical methods of treatment. Of medi- caments, two are pre-eminently useful: silver nitrate in 2% solution in new cases, particularly where the secretions are copious, applied with a brush or swab; and copper sulfate where the resorption of follicles is desired. The latter is best used in the crystal form, the so-called blue-stone or pencil, with which the en- tire conjunctival surface is gently and equably stroked once daily. Cold compresses are then applied, the use of the stone being discontinued, if the ophthalmic con- dition exhibits progressive irritation. If the patient is not seen daily by the physician, instillation of a V^fc solution of copper sulfate twice daily is prescribed, or it may be used in the form of a 1% unguent. Many physicians prefer Arlt's use of copper citrate, usually as unguent, and now obtainable, under the name of 69 cuprocitrol, in tubes of 1-5 grams, from the Schiirer V. Waldheimschen Apotheke in Vienna. With a glass rod some of this is rubbed once daily over the con- junctival surface. It is less irritant than other ap- plications, and, therefore, safer for the patient's own use. Iodine preparations are also frequently employed: Tinct. iodi, 1.0, glycerine, 15.0 as collyrium ; iodoform as dusting-powder or in unguent; pure iodine (V2-l%) dissolved in glycerine and daubed with a cotton appli- cation over the everted lids, or, a caustic pencil may be made of pure iodic acid moistened with a very lit- tle water until plastic, when it may be rolled on a glass plate into pencil form, and with this, cauterization may be performed about every third day. The pain is intense, but soon passes off. Of the mechanical procedures, that of Keinig is worthy of mention. A cotton applicator is dipped into a 1 :3000-5000 sublimate solution, and the cotton rubbed vigorously over the diseased mucosa, repeat- ing this every second day until the granules have dis- appeared. Operative methods have the advantage of greatly shortening the duration of the disease, a desideratum in epidemics. But, not all of them are radical, and it is always advisable to follow with medicamental treat- ment. With Knapp's roller- forceps, built on the plan of a clothes-wringer, the new-formed trachoma gran- ules may be expressed. In older, deeper infiltration, excision of the fornices or of the tarsus is recom- mended. Trachoma is infectious, and preventive measures are, therefore, to be prescribed- The, most dangerous carriers of the contagium are dirty wash-water and towels. 70 oil, Aims. lao.
