The condition sometimes resembles a target, or bulls-eye ring, on the retina surrounding the macula. In 1962, J Lawton Smith coined the term bull's eye maculopathy, regarded as the classic finding of macular toxicity. Many reports on chloroquine retinopathy exist. In contrast, only a few cases of hydroxychloroquine toxicity have been reported.
