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. Plaquenil medication side effects Hydroxychloroquine and yellow fever vaccine Extreme hunger plaquenil Hydroxychloroquine adderall interaction Hydroxychloroquine or chloroquine ingestion can cause atrophy of the retinal pigment epithelium in the form of a bull’s eye maculopathy in cases of chronic use. Early detection of toxicity prior to the development of the bull’s eye is important, as loss of visual acuity is usually irreversible at that stage. On examination, a telltale sign of hydroxychloroquine toxicity is a bilateral change in the retinal pigment epithelium of the macula that gives the commonly described appearance of a bull’s-eye. This is a late finding, however, and too late for screening to be useful. Later in the disease, patients can develop a bilateral bull's eye maculopathy, characterized by a ring of retinal pigment epithelium RPE depigmentation in the macula, sparing the fovea, which is often accompanied by paracentral and central scotomas. End stage hydroxychloroquine toxicity leads to widespread RPE and retinal atrophy with a loss. 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.

Chloroquine retinopathy, is a form of toxic retinopathy damage of the retina caused by the drugs chloroquine or hydroxychloroquine, which are sometimes used in the treatment of autoimmune disorders such as rheumatoid arthritis and systemic lupus erythematosus. This eye toxicity limits long-term use of the drugs. Advanced hydroxychloroquine toxicity presents as a bullseye maculopathy. Since retinal toxicity is usually irreversible, early detection of retinal toxicity and cessation of the offending agent is the best treatment 2 3. The condition sometimes resembles a target, or bulls-eye ring, on the retina surrounding the macula. Hydroxychloroquine retinopathy is extremely rare and is most often seen in cases where the dosage is high or the patient has been taking it for several years. Bulls-eye maculopathy is uncommon, but when it does occur, it can be devastating.
