In early toxicity, 75 % developed progression after drug cessation, including disruption of the parafoveal EZ and retinal pigment epithelium and thinning of the ONL. Eyes with obvious toxicity had greater inferior outer ring thinning 12 months after drug cessation compared to early toxicity p = 0.002, 95 % CI −2 to −8 μm. Ocular findings of HCQ retinal toxicity as detected by various screening modalities. A female patient was diagnosed with HCQ retinal toxicity at the age of 53 years, having taken HCQ for 12 years at 400 mg/day.
