Pattern of Retinopathy: Although the locus of toxic damage is parafoveal in many eyes, Asian patients often show an extramacular pattern of damage. Dose: We recommend a maximum daily HCQ use of 5.0 mg/kg real weight, which correlates better with risk than ideal weight. Sulfasalazine plaquenil Plaquenil lower seizure threshold Plaquenil can prove toxic to the retina, threatening the vision. Regular eye examinations are essential for those patients taking plaquenil because over time the retina can become damaged beyond repair. Regular medical monitoring is the only way to ensure that toxicity is not occurring. The actual incidence of retinal toxicity from hydroxychloroquine is difficult to pin down because there is usually a long time between being started on the drug and the start of any identifiable retinal toxicity. The overall rate of probable retinal toxicity is in the range of 1 of every 200 people treated. Dr. Noskow’s Case Report Plaquenil Toxicity Why it’s important to get your eyes routinely checked when on certain high- risk medications! What is plaquenil? Plaquenil is a medication commonly used in patients that have Rheumatoid Arthritis RA, Systemic Lupus Erythematosus SLE, Sjogrens Syndrome, and other inflammatory and autoiummune disorders. What are risk factors for developing Risk of Toxicity: The risk of toxicity is dependent on daily dose and duration of use. There are no similar demographic data for CQ, but dose comparisons in older literature suggest using 2.3 mg/kg real weight.

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. The Risk of Retinal Toxicity with Plaquenil. Dr. Noskow's Case Report Plaquenil Toxicity - Hollywood Eye.. Early Plaquenil Toxicity Detected without Bull’s Eye.. To report expanded SD-OCT findings of HCQ retinopathy that may assist the clinician in earlier diagnosis. 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. Although hydroxychloroquine retinal toxicity is thought to be rare, recent studies suggest it may have a higher prevalence than previously recognized. A large study examining patients with more than 5 years of HCQ use were evaluated with 10-2 visual fields or spectral-domain optical coherence tomography SD OCT. The risk of a toxicity sharply increases after 5 years, with majority of cases of retinotoxicity occurring in patients that have had a cumulative dose exceeding 1000g of hydroxychloriquine Plaquenil. This level is reached in about 7 years with the most common daily dose of Plaquenil, 400 mg/day 200 bid.
