Chloroquine is now uncommonly used in favor of its derivative hydroxychloroquine. In the United States, hydroxychloroquine is most often used for its anti-inflammatory effects in rheumatology and dermatology. Generic.plaquenil watson Plaquenil and pregnancy tests Plaquenil and liver transplant Hydroxychloroquine, sold under the brand name Plaquenil Sanofi-Aventis, is an antimalarial drug that has gained widespread use in treating various autoimmune diseases, including systemic lupus erythematosus and rheumatoid arthritis. 1 By some estimates, more than 150,000 patients are on long-term therapy with this medication in America alone. 2 Retinal toxicity associated with HCQ use is. Retinopathy before patients recognize visual loss. 3. The timing and extent of surveillance monitoring should take into account individual risk factors for toxicity related to hydroxychloroquine use. BACKGROUND 1 Hydroxychloroquine HCQ, brand name Plaquenil is commonly used for the long-term Many systemic medications may cause retinal toxicity. One such commonly used medication for dermatologic and rheumatologic inflammatory conditions is hydroxychloroquine Plaquenil, a chloroquine derivative. It is used to treat many diseases including malaria, rheumatoid arthritis and systemic lupus erythematosus. While early toxicity may be asymtomatic, patients with more advanced stage of toxicity may complain of color vision changes or paracentral scotomas. Its toxic effects on the retina are seen in the macula. Plaquenil retinopathy visual fields Hydroxychloroquine retinopathy Eye, AMERICAN COLLEGE OF RHEUMATOLOGY Tinnitus chloroquine Of 2361 patients who had taken hydroxychloroquine continuously for at least 5 years and who had 10-2 visual fields or SD-OCT, 177 7.5% showed clear signs of retinal toxicity. None of the primary medical indications for hydroxychloroquine therapy were significantly associated with an increased prevalence of retinal toxicity. Toxic Retinopathy With Hydroxychloroquine Therapy. Hydroxychloroquine-Induced Retinal Toxicity - American.. Humphrey Visual Field Findings in Hydroxychloroquine Toxicity. The main outcomes were toxicity as determined by characteristic visual field loss or retinal thinning and photoreceptor damage. They also examined risk factors and prevalence. The study findings revealed that when hydroxychloroquine was used at doses 5mg /kg, the risk of retinopathy was 1% in the first 5 yrs. 2% in 10 yrs. 20 % after 20 yrs.

Today it is recommended that every single person on Plaquenil get a visual field 10-2 test, plus one of the three other highly sensitive screening tests the FAF fundus autofluorescence imaging, the SD-OCT spectral domain optical coherence, or the multifocal electroretinogram mfERG,” Thomas says.
