Pattern of Retinopathy: Although the locus of toxic damage is parafoveal in many eyes, Asian patients often show an extramacular pattern of damage. Dose: We recommend a maximum daily HCQ use of 5.0 mg/kg real weight, which correlates better with risk than ideal weight.

A ring of hyper-autofluorescence along with parafoveal dark areas will be visible. Ocular findings of HCQ retinal toxicity as detected by various screening modalities. A female patient was diagnosed with HCQ retinal toxicity at the age of 53 years, having taken HCQ for 12 years at 400 mg/day. Evaluating Hydroxychloroquine Toxicity With Multifocal Electroretinography Toxicity first affects small areas of the retina. BY DONNELL J. CREEL, PhD Figure 1. Fundus photograph using autofluorescence to better designate retinal damage in the macula. This example depicts late-stage severe toxic effects. Risk of Toxicity: The risk of toxicity is dependent on daily dose and duration of use. There are no similar demographic data for CQ, but dose comparisons in older literature suggest using 2.3 mg/kg real weight.

Evaluating Hydroxychloroquine Toxicity With Multifocal.. Determine risk for hydroxychloroquine retinal toxicity.. Hydroxychloroquine HCQ is efficacious for various diseases1,2, but can produce “bulls-eye” retinopathy that decreases vision even after discontinuance3,4. Retinopathy can be present in 7.5% of patients after 5 or more years of HCQ treatment, increasing to 20% after 20 years2. In 2016, the American Academy of Ophthalmology published new recommendations for the evaluation of HCQ. Aug 06, 2014 Hydroxychloroquine, sold under the brand name Plaquenil Sanofi-Aventis, is an antimalarial drug that has gained widespread use in treating various autoimmune diseases, including systemic lupus erythematosus and rheumatoid arthritis. 1 By some estimates, more than 150,000 patients are on long-term therapy with this medication in America alone. 2. FAF is an objective imaging test that uses the properties of the RPE to detect early toxicity. In early hydroxychloroquine toxicity, FAF often shows subtle parafoveal hyperautofluorescence, thought to be related to increased lipofuscin activity in the RPE. 4 In later stages of disease, hypoautofluorescence will be noted and is an indication of.
