    Retinal toxicity of hydroxychloroquine


    In Sjögren’s, Plaquenil is used to treat many symptoms of Sjögren’s including fatigue, joint symptoms of arthritis and arthralgias (joint pain), dry mouth and dry eyes. Similar to its use in systemic lupus erythematosus, many clinicians feel that it is useful in reducing general Sjögren’s “disease activity.” One of the reasons that physicians feel comfortable in prescribing Plaquenil is its low risk to benefit ratio.

    Factors that increase the risk of developing hydroxychloroquine associated retinal toxicity include daily dose, cumulative dose, renal or liver impairment, older age, and prior retinal disease. Specifically, a daily dose of 6.5mg/kg based on ideal body weight and a cumulative dose of 1000g of hydroxychloroquine or 460g of chloroquine are both considered risk factors for retinal toxicity. PURPOSE To define the risk of hydroxychloroquine HCQ-related retinal toxicity in patients with rheumatoid arthritis RA and systemic lupus erythematosus SLE who are receiving recommended dosages of the drug or =6.5 mg/kg/day. 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.

    As with any medication, allergic reactions including skin rashes and non-allergic reactions can occur. This means that the side effects of Plaquenil are mild and infrequent compared with its potential benefits.

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 loss appear ie, before the appearance of bull’s eye maculopathy.

    How to Succeed in Plaquenil Screenings In early cases of Plaquenil toxicity, an early indicator of damage is the appearance of a paracentral scotoma seen on automated visual field testing in the absence of fundus changes. 18 Each of the testing strategies can be used to detect early toxicity changes, but the presentation of the visual field effects will vary. Due to the central area.
