    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.

    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. 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. Plaquenil is known to show retinal toxicity which can effect the vision and it is imperative to be able to spot any changes and to contact the patient's rheumatologist to notify them about the changes. The presentation goes over how to spot and what testing to perform to make sure there is no retinal toxicity.

    “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.

  4. 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.

    SD-OCT is capable of detecting characteristic macular changes of HCQ toxicity. These typical macular abnormalities include loss of the parafoveal ellipsoid zone EZ, parafoveal thinning of the outer nuclear layer ONL and inner plexiform layer IPL, the “flying saucer” sign, and peripapillary nerve fiber layer thinning 12 – 14. 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. Baseline fundus photographs and FA are helpful in patients with pre-existing macular pigmentary changes. Patients are classified as being at a higher risk of developing toxicity if they exceed 3 mg/kg/day of chloroquine, or 6.5 mg/kg/day of hydroxychloroquine calculated based on ideal body weight.

    In this post I'm going to highlight the Pulsing Xenia - one of the most unique soft corals available, but also a coral that needs to have a warning label for anyone looking to put one in their tank. It has study stalks covered with a crown of featherly polyps. Chloroquine Indications, Side Effects, Warnings - Chloroquine - Wikipedia Reef Medicine Series. Chloroquine Diphosphate
