    Macular oct changes in plaquenil toxicity


    There are hundreds of drugs with potential retinal toxicity—so many that the National Registry of Drug-Induced Ocular Side Effects doesn’t stratify them by incidence or effect, said Frederick W. “Rick” Fraunfelder, MD, director of the Registry and associate professor of ophthalmology at Oregon Health & Science University in Portland.

    Retinal toxicity associated with chronic exposure to hydroxychloroquine and its ocular screening. Fundus autofluorescence FAF indicates marked changes of macular toxicity in the mild and severe cases, represented by the central. Spectral-domain optical coherence tomography and adaptive optics may detect hydroxychloroquine retinal. The classic retinal changes appear as a “bull’s eye” area of discoloration of the central part of the retina. Symptoms of Plaquenil toxicity are similar to other macular problems and may include Decreased fine vision or difficulty reading. Changes in Color vision; Missing Spots or shadows near the center of the vision; Monitoring for. Repeat 10-2 HVF testing demonstrated the dense paracentral scotomas. SD-OCT showed loss of the parafoveal inner/outer segment junction, thinning of the parafoveal outer nuclear layer, and a loss of the normal foveal depression, which is characteristic for hydroxychloroquine retinal toxicity Figure 3.

    “It’s a pretty rare thing.” Nevertheless, he urged doctors to master the Academy’s new guidelines, because the effects from chloroquine and hydroxychloroquine, when they do occur, are severe and often irreversible. “Plaquenil toxicity isn’t even in the top 10, or the top 100” if you’re looking at incidence, he said.

    Jan 05, 2020 The early signs of hydroxychloroquine toxicity are macular edema and/or bilateral granular depigmentation of the RPE in the macula. With continued exposure to the drug, this can progress to an atrophic bullseye maculopathy with concentric rings of hypopigmentation and hyperpigmentation surrounding the fovea 2 3. Although the incidence of macular toxicity is infrequent with Plaquenil use at a dosage of 200mg or 400mg q.d. its visual impact can be devastating. 2,3 The associated classic retinal toxicity is described as a bull’s eye maculopathy ring of depigmented retinal pigment epithelium that spares the foveal area.

    Plaquenil for treatment - Lyme Disease - MedHelp Plaquenil is often perceived as an anti-arthritis drug used to treat connective tissue disorders. What it does is make the body more alkaline. My doc explained that he prescribes it with Biaxin Clarithromycin-an intracellular abx because by making the body more alkaline, the Biaxin can more easily penetrate the body's cells, which makes it up to 40% more effective.
