    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. Retinal toxicity from hydroxychloroquine use cannot be completely prevented, but effective screening should recognize retinal toxicity before symptoms or significant risk of central vision loss appear ie, before the appearance of bull’s eye maculopathy. I just went to Winston-Salem to see a retinal specialist and am waiting for his reply--he did say it looked suspicious for toxicity. I just read an article by a lady who has experienced the same visual disturbances and was diagnosed with toxicity and has been off plaquenil 2 years but her eyes are still getting worse.

    The toxicity resulting from the intake of Plaquenil is due to its affinity for melanin-containing structures in the body.

    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. Hence, it is imperative that we become familiar with recognizing the spectrum of HVF and SD-OCT findings associated with Plaquenil retinal toxicity. Of note, SD-OCT, in combination with Humphrey visual field testing, is critical for the early detection of Plaquenil retinal toxicity. Retinal toxicity is unpredictable and can occur even at relatively low doses of hydroxychloroquine. There are new screening modalities for early detection of asymptomatic hydroxychloroquine ocular toxicity.
