A recent study of 2361 patients in USA suggested that the prevalence of toxicity overall was 7.5% when using central visual field (VF) testing or spectral-domain optical coherence tomography (SD-OCT) to detect early changes [27] . If the OCT/FAF is suggestive of hydroxychloroquine toxicity, a field test is needed to establish whether the patient has either possible or definite retinopathy. In conclusion, using 2018 RCOphth diagnostic criteria, we found a prevalence of 1.6% of definite retinopathy and 4.7% of possible retinopathy in a group of 869 patients taking hydroxychloroquine for more than 5 years.	./cache/cord-335892-hwahcec5.txt	./txt/cord-335892-hwahcec5.txt
