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.

Within one year of starting hydroxychloroquine, you may be invited to a baseline screening. appointment. The purpose of this assessment is not to detect toxicity from hydroxychloroquine, but instead to ensure there are no other problems that will make screening for toxicity difficult in the future. In 2002, the American Academy of Ophthalmology AAO established ocular examination guidelines for screening patients on Plaquenil therapy. Testing included a comprehensive eye exam that consisted of an assessment of the posterior segment with careful evaluation of associated macular changes or signs of retinal disease. 4 Baseline fundus photography was considered as an optional test. Plaquenil” exam on visual field Red on white visual fields Some clinicians may prefer, however more difficult to interpret due to noisemore sensitive, less specific. Re-test for repeatability of defects. 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. Plaquenil ocular testing Plaquenil Risk Calculators, New Plaquenil Guidelines - Side effects stopping plaquenil The American Academy of Ophthalmology has published guidelines for monitoring patients for Plaquenil toxicity. Some cases are difficult to detect, especially if other eye problems are present. Current testing for Plaquenil toxicity may include Visual field testing to evaluate for missing spots near the center of the vision. Plaquenil Toxicity Screening - Retina Group of New York.

You can go to a normal opticians but make sure they know you are on hydroxychloroquine and expect them to do a peripheral vision field test that involves looking into a machine and pressing a button when you can see a flashing light in various places over a circle within the machine very easy, they can then tell if there is a problem with the peripheral vision which could be caused by the medication. Before beginning treatment with plaquenil, the doctor will perform a baseline eye examination and the following tests Dilated Retinal Examination, Retinal Photography, Visual Field Test, OCT. The risk of developing retinopathy increases with the length of time plaquenil has been taken and the dosage prescribed. Today it is recommended that every single person on Plaquenil get a visual field 10-2 test, plus one of the three other highly sensitive screening tests the FAF fundus autofluorescence imaging, the SD-OCT spectral domain optical coherence, or the multifocal electroretinogram mfERG,” Thomas says.
