Scanlon	The influence of age, duration of diabetes, cataract, and pupil size on image quality in digital photographic retinal screening	2006.0	6	.pdf	application/pdf	5087	405	59	OBJECTIVE — To evaluate the effect of age, duration of diabetes, cataract, and pupil size on Outcome measures were ungradable image rates, age, duration of diabetes, detection of referable diabetic retinopathy, presence of early or obvious central cataract, pupil diameter, and iris color. CONCLUSIONS — The strongest predictor of ungradable image rates, both for nonmydriatic and mydriatic digital photography, is the age of the person with diabetes. of ungradable image rates for nonmydriatic photography vary between 4% reported by Leese et al. The current study was designed to evaluate the effect of age, duration of diabetes, cataract, and pupil size photography in those patients with gradable images, the Gloucestershire Diabetic ungradable image in one or both eyes unless referable diabetic retinopathy was detected in either eye. (3,8) have reported nonmydriatic ungradable image rates �12%, but the average age of the study population was �55 screening for diabetic retinopathy by digital imaging photography and technician	./cache/work_kulpocb6vbh6ho74ysrhyvk7ae.pdf	./txt/work_kulpocb6vbh6ho74ysrhyvk7ae.txt
