    Plaquenil toxicity fundus autofluorescence


    In Sjögren’s, Plaquenil is used to treat many symptoms of Sjögren’s including fatigue, joint symptoms of arthritis and arthralgias (joint pain), dry mouth and dry eyes. Similar to its use in systemic lupus erythematosus, many clinicians feel that it is useful in reducing general Sjögren’s “disease activity.” One of the reasons that physicians feel comfortable in prescribing Plaquenil is its low risk to benefit ratio.

    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. Plaquenil is manufactured in only a 200 mg tablet The typical dosage is either 200 or 400 mg per day 200 mg daily puts anyone under 68 pounds at risk1 400 mg of Plaquenil daily puts anyone under 135 pounds at a higher risk for toxicity Therefore, 200mg of Plaquenil daily is going to be a safe dosage for virtually all adults13 Sep 15, 2014 Fundus autofluorescence FAF indicates marked changes of macular toxicity in the mild and severe cases, represented by the central mottled hypo autofluorescence with surrounding rim of hyper autofluorescence, due to the retinal pigment epithelium RPE loss. FAF is a sensitive indicator of the RPE degeneration caused by the toxic progression.

    As with any medication, allergic reactions including skin rashes and non-allergic reactions can occur. This means that the side effects of Plaquenil are mild and infrequent compared with its potential benefits.

    To detect chloroquine toxicity, the American Academy of Ophthalmology recommends performing fundus examinations, 10-2 automated visual fields, and at least one objective test multifocal electroretinography mfERG, fundus autofluorescence imaging, or spectraldomain optical coherence tomography SD-OCT. 1 By contrast, Amsler grid testing. Nov 01, 2015 Fundus autofluorescence FAF can potentially identify abnormalities in the RPE. Due to its sensitivity, it is possible to see autofluorescence changes even in early HCQ toxicity. Early toxicity may present as fine annular hyperautofluorescence. 2 The American Academy of Ophthalmology released an updated set of screening recommendations for hydroxychloroquine Plaquenil and chloroquine to account for the many studies that have shown the effects of these medications on the retina 1. It succinctly makes the case for screening, and

    Has anyone had retinal damage from Plaquenil? - Lupus - Inspire Anyone on Plaquenil is almost always ordered to have annual visits with a Retinologist for those tests and have a baseline test at beginning of Plaquenil to determine if damage occurs. Did a retina specialist say there was retina "thinning"?
