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. Hydroxychloroquine sulphate weight gain Plaquenil retinopathy pathogenesis Chloroquine glioblastoma Cymbalta and plaquenil 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. On examination, a telltale sign of hydroxychloroquine toxicity is a bilateral change in the retinal pigment epithelium of the macula that gives the commonly described appearance of a bull’s-eye. This is a late finding, however, and too late for screening to be useful. “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.

Plaquenil Toxicity - Bennett & Bloom Eye Centers. Hydroxychloroquine-Induced Retinal Toxicity - American.. Expanded spectral domain-OCT findings in the early.. Plaquenil, widely used to treat lupus, rheumatoid arthritis and other inflammatory and dermatologic conditions, is very effective, and “the risk of toxicity in the first five years for someone without special risk factors is very low,” Dr. Marmor said. However, risk increases with duration of use. Plaquenil Toxicity - Bulls Eye Maculopathy 878 views 70-year-old woman with systemic Lupus erythematosus and clotting problems. She was on the Plaquenil for about eight years and then off the Plaquenil for the last eight years because she developed macular toxicity. Although her vision was hazy, it was stable. Because early toxicity changes can be revealed on SD-OCT, it is prudent to perform a baseline screening of patients taking Plaquenil. Multifocal ERG has the ability to detect early macular dysfunction, so it should be included as part of baseline screening. A maximum daily dose of Plaquenil of 5.0mg/kg real weight is recommended.
