Once retinal toxicity from hydroxychloroquine occurs, it is thought that the retinal changes are permanent and the disease can progress even if hydroxychloroquine is stopped for 1 to 3 years. Chloroquine and hydroxychloroquine can cause toxic retinopathy due to their binding of melanin in the retinal pigmented epithelium RPE as well as direct toxicity to retinal ganglion cells. Early findings include mottling of the RPE and blunted foveal reflex. As the retinopathy progresses, a bull's-eye maculopathy develops, as seen in these photos. In 1959, Hobbs established a definite link between long-term use of chloroquine and subsequent development of retinal pathology. 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.
