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 incidence or effect, said Frederick W. “Rick” Fraunfelder, MD, director of the Registry and associate professor of ophthalmology at Oregon Health & Science University in Portland. Plaquenil cardiotoxicity Hydroxychloroquine and neutropenia He pointed out that the goal of the AAO is not to stop using an excellent drug but to reduce the recommended dose and to screen for early abnormalities. Dr. Rosenbaum reviewed the guidelines from the American College of Rheumatology, which are generally nonspecific regarding exactly how hydroxychloroquine should be used. He showed evidence that. Oct 30, 2019 Based on these risks, the American Academy of Ophthalmology AAO recommends not exceeding a daily hydroxychloroquine dosage of 5 mg/kg using actual body weight in most patients. Previous recommendations to use ideal body weight are no longer advised; very thin patients in particular were at increased risk for retinal toxicity using this practice. Irreversible retinal damage observed in some patients who had received hydroxychloroquine sulfate; significant risk factors for retinal damage include daily doses of hydroxychloroquine sulfate greater than 6.5 mg/kg 5 mg/kg base of actual body weight, durations of use greater than five years, subnormal glomerular filtration. “It’s a pretty rare thing.” Nevertheless, he urged doctors to master the Academy’s new guidelines, because the effects from chloroquine and hydroxychloroquine, when they do occur, are severe and often irreversible. “Plaquenil toxicity isn’t even in the top 10, or the top 100” if you’re looking at incidence, he said.

The 20 American Academy of Ophthalmology AAO guidelines for screening for hydroxychloroquine retinopathy HR recognized the importance of ideal body weight IBW as opposed to real body weight RBW in determining the safe daily dosing.1, 2 The guidelines state 1 “Obesity is a risk factor because the antimalarials are not retained in fatty tissues. Nov 10, 2019 American Academy of Ophthalmology AAO 2016 guidelines recommend to use HCQ at dosages ≤5 mg/kg real body weight to minimize toxicity 1. Important risk factors for retinal toxicity are daily and cumulative dosage of HCQ, duration of treatment, patient age and concomitant renal or liver diseases 1.
