    Retinal toxicity of Plaquenil may manifest itself with subtle disturbances of the retinal pigment epithelium which may eventually lead to complete destruction of the macula in the form of bull’s-eye maculopathy. The characteristics of patients which may increase of developing toxicity symptoms while taking Plaquenil include an age of more than 60 years old, having renal or hepatic insufficiency or any existing macular degeneration and retinal disease 1. In obvious toxicity, the nasal inner subfield showed more thinning than the temporal inner subfield at 12 months after drug cessation p = 0.018, 95 % CI −1 to −8 μm. Conclusions Once HCQ retinopathy is diagnosed and the medication is discontinued, structural retinal changes commonly occur.

    Main Outcome Measures: SD-OCT findings suggestive of HCQ retinopathy before parafoveal ellipsoid disruption. Retrospective clinical data review by the Boston Image Reading Center.

There is damage visible in the outer retina in a perifoveal distribution. Related files It is crucial to detect retinal toxicity induced by HCQ early and take necessary actions before it results in permanent visual loss. In our study, we demonstrated HCQ-induced retinal toxicity at an earlier stage through the measurement of RGC-IPL thickness by using SD-OCT, which is an easy-to-use and non- invasive method.
