In this article, new recommendations were made that changed the previous monitoring paradigm. More importantly, it has repositioned hydroxychloroquine from one of the safest medications that rheumatologists use to a drug that can have potentially significant ocular morbidity (if used in doses greater than 5 mg per kilogram and or for prolonged periods of time). Chloroquine vs zika Symptoms of plaquenil eye problems Ra plaquenil success rates Ocular Surgery News The American Academy of Ophthalmology has published several dosing and screening recommendations for hydroxychloroquine to avoid potential retinal toxicity, yet some patients. 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. Apr 20, 2011 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. The previous AAO guideline recommended screening every 12 months. It has become fairly common practice for most rheumatologists to recommend that patients being treated with hydroxychloroquine be seen for formal visual field evaluation once or twice a year to monitor for retinal toxicity.

Plaquenil Toxicity - Bennett & Bloom Eye Centers. New Plaquenil Guidelines. Plaquenil Toxicity - Symptoms, Treatment, Risk Factors, Retinopathy. Plaquenil-induced toxicity usually will not occur before five years of taking the drug. “Eye damage due to Plaquenil is not common,” he says. “Rarely will anybody who has good vision and minimal symptoms develop loss of central vision or ability to read if annual screening is done and visual are symptoms reported as soon as they occur so the medication can be stopped if toxicity occurs. Chloroquine CQ is used to prevent and treat malaria and amebiasis,1 while hydroxychloroquine HCQ, a less toxic metabolite of chloroquine, is used to treat rheumatic diseases such as systemic lupus erythematosus SLE, rheumatoid arthritis RA, juvenile idiopathic arthritis JIA and Sjogren's syndrome.2 Both medications can cause corneal deposits, posterior subcapsular lens opacity. AT A GLANCE • Long-term use of hydroxychloroquine sulfate may result in parafoveal retinal toxicity. • No single imaging platform can confirm the presence of hydroxychloroquine toxicity, but a combination of imaging tests can provide ample evidence for diagnosis.
