Chloroquine rheumatoid arthritis mechanism of action Plaquenil sleep disturbance Plaquenil and lupus nephritis Plaquenil lymphoma Our patient demonstrates the importance of using the new recommended screening tools for the detection of early hydroxychloroquine toxicity. 10-2 HVF, SD-OCT, autofluorescence, or mfERG might have detected the hydroxychloroquine retinal toxicity on the day of her presenting symptoms and possibly earlier, potentially limiting the amount of. Abstract. Background The American Academy of Ophthalmology recommendations on screening for chloroquine CQ and hydroxychloroquine HCQ retinopathy are revised in light of new information about the prevalence of toxicity, risk factors, fundus distribution, and effectiveness of screening tools. Pattern of Retinopathy Although the locus of toxic damage is parafoveal in many eyes, Asian. In early toxicity there are no visible signs, but field, OCT and mfERG changes can be detected. If abnormalities are present only unilaterally, investigate other causes besides hydroxychloroquine toxicity see “Differential Diagnosis of Bull’s-Eye Maculopathy”. Mechanism of Toxicity Chloroquine is now uncommonly used in favor of its derivative hydroxychloroquine. This article focuses upon hydroxychloroquine retinopathy. Chloroquine was originally used as an anti-malarial therapeutic. Early plaquenil toxicity oct Multimodal Imaging in Plaquenil Toxicity, Recommendations on Screening for Chloroquine and.
