    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.

    Some side effects of hydroxychloroquine may occur that usually do not need medical attention. These side effects may go away during treatment as your body adjusts to the medicine. Also, your health care professional may be able to tell you about ways to prevent or reduce some of these side effects. Nov 01, 2015 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. Previously described OCT findings in HCQ toxicity include loss of the external limiting membrane, disruption of the outer ellipsoid zone, parafoveal thinning of the outer nuclear layer and RPE damage. 6,7,10 Despite these various changes, numerous studies have supported the notion that relative “foveal resistance” is common in HCQ toxicity, as demonstrated by preservation of the subfoveal outer retinal layers, accounting for the intact central visual acuity that can be seen even in.

    “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.

  7. 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.

    Early macular toxicity can cause stippling or mottling of the RPE Next, granular pigmentation and loss of the normal foveal reflex can occur It’s believed but not proven that if early macular changes are detected and the medication is stopped, any toxicity that has occurred can be reversed.1 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. 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.

    Suppression: 400 mg (310 mg base) orally on the same day every week Comments: -Suppressive therapy should begin 2 weeks prior to exposure; however, failing this, an initial dose of 800 mg (620 mg base) may be taken in 2 divided doses (6 hours apart).

    Plaquenil therapy and eye exams. - Eye Care - MedHelp I was told from the start by my rheumatologist I would have to have eye exams including visual field exams every six months due to the plaquenil therapy. My first two exams did include these tests. But my next six month appointment is coming up, and they told me I didn't need the visual field test this time so the appointment would be shorter.
