    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.

    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. 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. Hydroxychloroquine is metabolized and secreted by both the liver and the kidneys. Therefore, disturbed renal or hepatic function might reduce HCQ clearance and increase the propensity for toxicity. Older age may also be associated with increased risk of macular toxicity, possibly due to the pre-existence.

    “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.

    Lyons emphasizes the importance of annual screening and says that, although annual screening is recommended for everyone taking Plaquenil, it is imperative for people who have been taking the medication for more than 10 years, who have a higher incidence of retinal toxicity. Several risk factors may increase the likelihood of retinal toxicity from Plaquenil such as, age of greater than 60 years, daily dose more than 6.5 mg/kg; use of the drug more than 5 years, obesity, preexisting retinal disease and, renal or liver failure. My mother was diagnosed with Plaquenil Toxicity in 2007 she first noticed changes in 2006, although being followed by her eye doctor they failed to notice this as Plaquenil TX until it was to late. After the medicine was Discontinued she continued to have more and more visual changes for the worse and still is declining in her vision.

  7. How long did Plaquenil/Hydroxychloroquine take? DailyStrength I take methotrexate injections weekly along with antibotic thereaphy of 200 mg of minocycline. Last week my doc added plaquenil to the mix. I have a pharmacist friend that says it can take up to a year to work, but once its kicks in it can be really good. I suggest you ask your rhuemie for additional help in the meantime.
