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). Is hydroxychloroquine a blood thinner Side effects plaquenil 200 mg Patients with pre-existing retinopathy of the eye — this is a relative contraindication in that it makes patient monitoring more difficult. Tell me more about hydroxychloroquine. Hydroxychloroquine has a lower risk of ocular toxicity, both corneal and retinal, compared with chloroquine. Who Is at Risk for Vision Loss with Plaquenil. You will have a “baseline” eye exam. This measures the health of your eyes and looks for retinal or macular. 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. “Rick” Fraunfelder, MD, director of the Registry and associate professor of ophthalmology at Oregon Health & Science University in Portland. 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.

Recommendations on Screening for Chloroquine and Hydroxychloroquine.. Rx Side Effects New Plaquenil Guidelines and More.. Conclusion. Patients and their physicians prescribing hydroxychloroquine need to be keenly aware of retinal toxicity risks and the importance of regular screening, and ophthalmologists who see these patients should keep retinal toxicity in the front of their minds. Taking hydroxychloroquine for more than five years may develop retinopathy that can be detected with specialised tests. The risk is much higher in patients who have been taking the drug for 20 years or more. In these patients between 20 and 50 out of 100 will develop retinopathy.

A task force of the American Academy of Ophthalmology published screening guidelines in 2002. However, new data indicate that the incidence of hydroxychloroquine toxicity may be higher than previously thought.
