    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.

Related files Retinal toxicity from hydroxychloroquine is rare, but even if the medication is discontinued, vision loss may be irreversible and may continue to progress. It is imperative that patients and physicians are aware of and watch for this drug’s ocular side effects. Mar 01, 2011 Hydroxychloroquine Plaquenil, Sanofi-Aventis remains widely used in the treatment of various rheumatologic disorders. A small percentage of patients exposed to hydroxychloroquine will develop irreversible, and potentially progressive, retinal toxicity for which no effective treatment exists.

    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.

  4. 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.

    Sep 15, 2015 In addition to traditional 10-2 threshold visual field testing, FAF is among the objective tools that may be used as part of the screening process for hydroxychloroquine maculopathy. A ring of hyper-autofluorescence along with parafoveal dark areas will be visible. Recommendations on Screening for Chloroquine and Hydroxychloroquine Retinopathy Retinal toxicity from chloroquine CQ and its analogue, hydroxychloroquine HCQ, has been recognized for many years. Chloroquine toxicity remains a problem in many parts of the world, but is seen less frequently in the United States where the drug largely has been replaced by HCQ. Other useful screening tests are multifocal electroretinogram mfERG and fundus autofluorescence FAF. It is not advised and/or is no longer standard of care to order fundus photos, time-domain OCT, FA, full-field ERG, Amsler grids, color vision testing, or electrooculography EOG to screen for Plaquenil toxicity.

    Repurposing of the anti-malaria drug chloroquine for Zika Virus. One of the major challenges of the current Zika virus ZIKV epidemic is to prevent congenital foetal abnormalities, including microcephaly, following ZIKV infection of pregnant women. Given the urgent need for ZIKV prophylaxis and treatment, repurposing of approved drugs appears to be a viable and immediate solution.
