Toxicidade ocular causada pela cloroquina: relato de caso

Abstract

To report a case of ocular toxicity due to chloroquine. The best visual acuity was measured in both eyes with the Snellen chart. Slit-lamp examination of anterior segment, refraction, dilated fundus examination, fluorescein angiography and retinography was done in a 53-year-old patient, female, with rheumatoid arthritis. She had used chloroquine during 6 years and had stopped for 1 year when she came to our service. She had best corrected visual acuity of 20/200 and 20/40. Slit-lamp examination showed intraocular lens in right eye and nuclear cataract (1+/4) in the other, and bilateral corneal subepithelial opacity inferior to the visual axis. Fundus examination showed macular area with retinal pigment epithelium atrophy. Fluorescein angiography showed a bull's eye maculopathy. Report of a typical keratopathy and maculopathy caused by chloroquine.
