    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.

    The AAO published dosing and screening recommendations for chloroquine and hydroxychloroquine in 2016, revising previous recommendations published in 2011. The current maximum daily HCQ dose recommended by the AAO is 5 mg/kg of real weight. One reaches a cumulative dose of 1000 grams 1 kilogram at 7 years when taking the most commonly prescribed dose of 400 mg a day. A new study then focused on those patients that had taken HCQ over 5 years. This study revealed a much higher overall risk of 7.5% retinal toxicity among the 2361 patients studied. Although it is considered rare, retinal toxicity from the intake of Plaquenil can be irreversible even if the drug is discontinued 2, 3. What is Plaquenil Toxicity?
