Importance Hydroxychloroquine sulfate retinopathy can progress after the drug is stopped. It is not clear how this relates to the stage of retinopathy or whether early screening with modern imaging technology can prevent progression and visual loss. The present study reports data on 11 cases of hydroxychloroquine retinopathy that were monitored for 13 to 51 months after cessation of the drug. These cases are identical, with those studied previously with clinical data, although several now have a longer period of follow-up.

There is limited data regarding structural and functional changes of HCQ retinopathy after drug cessation 5–7. Studies from the 1960s and 1970s evaluated individuals taking the more toxic, related drug chloroquine, but were limited to visual acuity, visual fields, and fundus examination to assess for progression of retinopathy.
