    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.

    Hydroxychloroquine and chloroquin Hydroxychloroquine sulphate mechanism of action

    Rheumatologists use hydroxychloroquine sulfate Plaquenil, Concordia Pharmaceuticals to treat autoimmune diseases, namely discoid or systemic lupus erythematosus, rheumatoid arthritis, Sjögren syndrome, and malaria. When taken at high doses and for long durations, hydroxychloroquine has been known to cause parafoveal retinal toxicity. The American Academy of Ophthalmology has published several dosing and screening recommendations for hydroxychloroquine to avoid potential retinal toxicity, yet some patients still experience permanent vision loss resulting from hydroxychloroquine retinopathy due to improper dosing of the drug and improper screening. Mar 18, 2016 The researchers observed no significant differences or change in measurements of inner retinal thickness in different retinal regions between short- and long-term hydroxychloroquine users 27 patients, and during a median follow-up of 39 months 15 patients.

    “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.

Currently, one of the primary functional screening tests recommended for the evaluation of Plaquenil retinal toxicity is 10-2 white stimulus automated visual fields; however, research shows Asian patients benefited from 24-2 or 30-2 visual fields, given that toxicity often manifests changes beyond the macula in these patients. 9 Because spectral-domain optical coherence tomography SD-OCT is readily accessible and able to detect early structural damage prior to clinical funduscopic findings. The incidence of retinal toxicity is associated with the cumulative dose of the drug, increasing significantly beyond 1,000 g of HCQ. This cumulative dose is created when the common dose of 400 mg/day is used for 6.8 years. Hydroxychloroquine is metabolized and secreted by both the liver and the kidneys.
