    Hydroxychloroquine HCQ is an anti-malarial medication that has in recent times been utilized as treatment for a variety of autoimmune diseases, such as rheumatoid arthritis and systemic lupus erythematosus, and other inflammatory and dermatologic conditions. Retinal toxicity from HCQ, and its analog, chloroquine, has been recognized for many years.2,3 By some estimates, in the United. To detect chloroquine toxicity, the American Academy of Ophthalmology recommends performing fundus examinations, 10-2 automated visual fields, and at least one objective test multifocal electroretinography mfERG, fundus autofluorescence imaging, or spectraldomain optical coherence tomography SD-OCT. 1 By contrast, Amsler grid testing. Innovative Eye Care uses the top of the range Heidelberg Blue laser autofluorescence to take high definition images of the retina. This offers diagnostic insights into a number of retinal conditions, including macular degeneration, plaquenil toxicity, and hereditary diseases.

    It is imperative that patients and physicians are aware of and watch for this drug’s ocular side effects. Retinal toxicity from hydroxychloroquine is rare, but even if the medication is discontinued, vision loss may be irreversible and may continue to progress.

    Hydroxychloroquine sulfate HCQ, Plaquenil is an analogue of chloroquine CQ, an antimalarial agent, used for the treatment of systemic lupus erythematosus, rheumatoid arthritis and other autoimmune disorders. Its use has been associated with severe retinal toxicity, requiring a discontinuation of therapy. Plaquenil is manufactured in only a 200 mg tablet The typical dosage is either 200 or 400 mg per day 200 mg daily puts anyone under 68 pounds at risk1 400 mg of Plaquenil daily puts anyone under 135 pounds at a higher risk for toxicity Therefore, 200mg of Plaquenil daily is going to be a safe dosage for virtually all adults13 Hydroxychloroquine Plaquenil, Sanofi-Aventis remains widely used in the treatment of various rheumatologic disorders. A small percentage of patients exposed to hydroxychloroquine will develop irreversible, and potentially progressive, retinal toxicity for which no effective treatment exists.
