Her rheumatologist instructed her to undergo a baseline ocular examination prior to initiating Plaquenil (hydroxychloroquine, Sanofi-Aventis) therapy. Toxic maculopathy associated with chloroquine use was first documented in the literature five decades ago.1 In the United States, Plaquenil––an analog to chloroquine––is used to treat a variety of conditions, including rheumatoid arthritis, lupus and several distinct inflammatory disorders. 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. Plaquenil for ashy dermatosis What is chloroquine Mefloquine or plaquenil Download PDF. Drug-induced ocular side effects are back in the spotlight, thanks to the Academy’s revision of its recommendations on screening for retinal toxicity from chloroquine and its analogue hydroxychloroquine Plaquenil. 1 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. Retinal toxicity from hydroxychloroquine use cannot be completely prevented, but effective screening should recognize retinal toxicity before symptoms or significant risk of central vision loss appear ie, before the appearance of bull’s eye maculopathy. Screening requires the use of tests, such as 10–2 visual fields and SD-OCT and. Diagnosis Hydroxychloroquine-induced retinal toxicity Discussion. Chloroquine CQ and hydroxychloroquine Plaquenil HCQ have been used for many years, initially for the treatment of malaria but now more commonly for the treatment of inflammatory diseases such as rheumatoid arthritis and lupus 1. Initially, central visual acuity may be unaffected, but the patient may notice related paracentral scotomas that often interfere with reading. The associated classic retinal toxicity is described as a bull’s eye maculopathy (ring of depigmented retinal pigment epithelium that spares the foveal area). Plaquenil toxicity retina Hydroxychloroquine toxicity - EyeWiki, Plaquenil Risk Calculators Plaquenil 200 mg cenaPlaquenil use for lupus Retinal toxicity is a very rare side effect of the hydroxychloroquine therapy, but when it has occurred, vision loss may be permanent and may progress even years after the cessation of medication. Patients would be examined every 3 months, then annually, until they are stabled. Retinal toxicity associated with chronic exposure to hydroxychloroquine.. Hydroxychloroquine Plaquenil Toxicity and Recommendations.. Retinal toxicity associated with chronic exposure to.. Research has shown that your risk of developing retinopathy is higher the longer you are taking Plaquenil. In fact, the incidence of retinal toxicity rises sharply in people that have taken it between 5 and 7 years. As a result, baseline testing should occur within the first year of taking the drug and then annually at the five-year mark. Over time, Plaquenil can accumulate in the retina and cause permanent irreversible damage to the center of vision. The classic retinal changes appear as a “bull’s eye” area of discoloration of the central part of the retina. Symptoms of Plaquenil toxicity are similar to other macular problems and may include However, risk increases with duration of use, and the guidelines call for annual screening after five years, or sooner if there are “unusual risk factors or a suspicion of early toxicity.” Anne E. Fung, MD, a retina specialist at Pacific Eye Associates in San Francisco, averages one Plaquenil screening a week, due to her close affiliation.
