Concomitant renal or liver disease because the drug is cleared by both routes underlying retinal disease or maculopathy ; age greater than 60 years. Monitoring Guidelines. Guidelines on screening for retinopathy associated with hydroxychloroquine toxicity were initially published by the Academy in 2002. IMPORTANCE Hydroxychloroquine sulfate is widely used for the long-term treatment of autoimmune conditions but can cause irreversible toxic retinopathy. Prior estimations of risk were low but were based largely on short-term users or severe retinal toxicity bull's eye maculopathy.
