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.

Eye Exam and Testing for Plaquenil. For the first 5 years annual screening is appropriate. In addition to the previous discussion of a thorough complete eye exam with best corrected vision, central visual field, color vision, and dilated retinal exam, other tests include multifocal ERG, spectral domain OCT, and autofluoresence of the macula. 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. 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.

Its use has been associated with severe retinal toxicity, requiring a discontinuation of therapy. Retinal toxicity associated with chronic exposure to..

The global or full-field electroretinogram ERG is a mass electrical response of the retina to photic stimulation. The ERG is a test used worldwide to assess the status of the retina in eye diseases in human patients and in laboratory animals used as models of retinal disease. Handheld SD-OCT revealed severe attenuation of the outer retina throughout the macula, but with preservation of outer retinal structures in the fovea. PMM2-CDG is a rare congenital disorder for which both ff-ERG and SD-OCT were useful in demonstrating early changes of retinal architecture and function. To detect chloroquine toxicity. Plaquenil toxicity first affects small areas of the retina between 5° and 15° from the fovea. Figures 2 and 3 show three patients at different stages of toxicity. Patient B shows a less severe stage of toxicity with small islands of retinal damage in the areas 5° to 15° from the fovea. CONCLUSION.
