    The most common side effect associated with its use is retinal toxicity, which may be irreversible. Therefore, it is pertinent to know the findings, risk factors, and screening tests necessary to prevent retinal damage.

    This occurs when melanin is able to bind to the “High Risk Medication” Plaquenil within the Retinal Pigment Epithelium RPE as well as direct toxicity to retinal ganglion cells. The drugs ability to bind to these pigmented cells creates a “Bulls Eye” around the macula, giving it this very unique appearance. Once retinal toxicity from hydroxychloroquine occurs, it is thought that the retinal changes are permanent and the disease can progress even if hydroxychloroquine is stopped for 1 to 3 years. Newer techniques for evaluation of retinal disease have been developed and these techniques can detect retinal toxicity earlier. Sep 15, 2014 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.

Plaquenil Toxicity Plaquenil hydroxychloroquine is a medicine commonly used to treat patients with systemic lupus erythematosus and rheumatoid arthritis. After prolonged use, it can sometimes damage the macula and cause central vision loss. If we extrapolate the use of long-term hydroxychloroquine at KPNC to the entire US population, approximately 350 000 patients should receive annual eye screening by current guidelines. 9 Therefore, screening for hydroxychloroquine retinal toxicity is an important economic and patient safety issue. Retinal toxicity from hydroxychloroquine use cannot be completely prevented, but effective screening should recognize retinal toxicity before symptoms or significant risk of central visual field.
