    The more serious side effect is the retinal toxicity possibility. Initially early retinal findings are often asymptomatic despite some subtle blind spots. Later patients can develop a bilateral “bull’s eye maculopathy,” which is where a ring of retinal base retinal pigment epithelium is effected and lost. 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. Bull’s Eye Retinopathy Early macular toxicity can cause stippling or mottling of the RPE Next, granular pigmentation and loss of the normal foveal reflex can occur It’s believed but not proven that if early macular changes are detected and the medication is stopped, any toxicity that has occurred can be reversed.1 If the maculopathy continues to progress, concentric zones of.
