The toxicities can be grouped into categories such as pigmentary retinopathies, crystalline retinopathies, retinal vasculopathies, and retinopathies characterized by retinal edema or folds. Here we present a case of topiramate (Topamax, Ortho-Mc Neil Neurologics) causing transient angle closure and retinal folds. Plaquenil side effects kidney Teva chloroquine and alcohol Lupus hydroxychloroquine side effects Hydroxychloroquine lab test However, it can produce irreversible changes to the retina that lead to visual impairment. The aim of this study was to determine the proportion of patients treated with HCQ who develop retinal toxicity and the risk factors for the development of HCQ-induced retinal toxicity among Iranian patients. Review of Optometry presents Retina Revealed Case Studies. Plaquenil Induced Retinal Toxicity Abstract Background The American Academy of Ophthalmology recommendations on screening for chloroquine CQ and hydroxychloroquine HCQ retinopathy are revised in light of new information about the prevalence of toxicity, risk factors, fundus distribution, and effectiveness of screening tools. A 26-year-old woman reported to the emergency room with a chief complaint of sudden, painless loss of vision in both eyes. We follow with a review of the literature regarding topiramate toxicity, as well as a brief review of the other major categories of pharmacologic retinal toxicity.

Hydroxychloroquine-induced retinal toxicity in an.. Recommendations on Screening for Chloroquine and.. Plaquenil Toxicity - Bennett & Bloom. 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. 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. Hydroxychloroquine sulfate HCQ, Plaquenil is an analogue of chloroquine CQ, an antimalarial agent, used for the treatment of systemic lupus erythematosus, rheumatoid arthritis and other autoimmune disorders. Its use has been associated with severe retinal toxicity, requiring a discontinuation of therapy.
