Hydroxychloroquine and CQ retinopathy can progress even after the drugs are stopped, although the amount of progression and the risk to vision are functions of the severity of retinopathy at the time it is detected. 5,11 It seems doubtful that this late progression of damage after stopping the drug results from a continued reservoir of the drug, although clearance from the body does take many late progression may represent a gradual decompensation of cells that were injured. Although retinal toxicity is uncommon in the large number of patients who use hydroxychloroquine worldwide and derive great benefit from the therapy, our series suggests that the prevalence of retinopathy and risk of progression despite cessation of the drug may be higher than currently thought.
