To characterize structural changes of HCQ retinopathy with SD-OCT after drug cessation. Setting: Private practice and academic institution. Patient Population: Patients at New England Eye Center and Ophthalmic Consultants of Boston in Boston, MA diagnosed with HCQ retinopathy and followed after drug cessation. Hydroxychloroquine sickle cell What test is used when you take plaquenil Is it ok to get flu shot while taking plaquenil Hydroxychloroquine diabetes Hydroxychloroquine Macular Toxicity. Hydroxychloroquine is an immunomodulating drug that is commonly used in treating collagen vascular diseases such as rheumatoid arthritis and systemic lupus erythematosus. It has the serious side effect that it can cause irreversible macular damage when used in toxic doses over enough time. The side effect that is of greatest concern is retinal toxicity. Retinal toxicity of Plaquenil may manifest itself with subtle disturbances of the retinal pigment epithelium which may eventually lead to complete destruction of the macula in the form of bull’s-eye maculopathy. 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. Main Outcome Measures: SD-OCT findings suggestive of HCQ retinopathy before parafoveal ellipsoid disruption. Retrospective clinical data review by the Boston Image Reading Center. Plaquenil toxicity macular oct Retinal Physician - Hydroxychloroquine Maculopathy An Update., The Risk of Retinal Toxicity with Plaquenil Chloroquine phosphate malaria side effectsHydroxychloroquine sulfate and hydroxychloroquine sulfate plaqueni There is no single best test for detecting hydroxychloroquine toxicity. However, SD-OCT and VF are good screening tests, and FAF and mfERG can help confirm a diagnosis of suspected retinal toxicity from hydroxychloroquine. Early detection of toxicity is critical to prevent permanent visual loss. 1. Jorge A, Ung C, Young L, Melles RB, Choi HK. Retina Today - Imaging in Hydroxychloroquine Toxicity.. Hydroxychloroquine Plaquenil Toxicity and Recommendations.. How to Succeed in Plaquenil Screenings. 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. 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. Conclusions SD-OCT and AO detected abnormalities that correlate topographically with visual field loss from hydroxychloroquine toxicity as demonstrated by HVF 10-2 and may be useful in the detection of subclinical abnormalities that precede symptoms or objective visual field loss.
