    Nevertheless, retinopathy begins to appear with long-term use, and retinopathy is serious insofar as there is no known treatment. It can progress for a year or more after stopping the drug and, if not recognized early (at the point of screening), it can lead to functional blindness.

    We now know that bull’s-eye maculopathy is a late finding and may be associated with vision loss. Asians have a slightly different clinical presentation 3-4. Several recent studies have shown that instead of the classic perifoveal changes typical of hydroxychloroquine toxicity, Asians with retinal toxicity have a more peripheral pattern. 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 eye toxicity limits long-term use of the drugs.

    Sep 15, 2014 The retinopathy, funduscopically visible bull’s eye maculopathy, indicates that severe toxicity has determined irreversible degeneration of the retinal pigment epithelium and since it is already a late stage, a screening test is not necessary anymore. 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. 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.
