    There are hundreds of drugs with potential retinal toxicity—so many that the National Registry of Drug-Induced Ocular Side Effects doesn’t stratify them by incidence or effect, said Frederick W. “Rick” Fraunfelder, MD, director of the Registry and associate professor of ophthalmology at Oregon Health & Science University in Portland.

    Currently, one of the primary functional screening tests recommended for the evaluation of Plaquenil retinal toxicity is 10-2 white stimulus automated visual fields; however, research shows Asian patients benefited from 24-2 or 30-2 visual fields, given that toxicity often manifests changes beyond the macula in these patients. 9 Because spectral-domain optical coherence tomography SD-OCT is readily accessible and able to detect early structural damage prior to clinical funduscopic findings. Hydroxychloroquine sulfate HCQ, Plaquenil is an analogue of chloroquine CQ, an antimalarial agent, used for the treatment of systemic lupus erythematosus, rheumatoid arthritis and other autoimmune disorders. Its use has been associated with severe retinal toxicity, requiring a discontinuation of therapy. Aug 29, 2014 Several risk factors may increase the likelihood of retinal toxicity from Plaquenil such as, age of greater than 60 years, daily dose more than 6.5 mg/kg; use of the drug more than 5 years, obesity, preexisting retinal disease and, renal or liver failure.

This 68 year old woman with systemic lupus erythematosus had been on hydroxychloroquine at a dosage of 400 mg/d 6.52 mg/kg/d for eight years. Mar 18, 2016 The researchers observed no significant differences or change in measurements of inner retinal thickness in different retinal regions between short- and long-term hydroxychloroquine users 27 patients, and during a median follow-up of 39 months 15 patients.
