    Jan 05, 2020 Its toxic effects on the retina are seen in the macula. While early toxicity may be asymtomatic, patients with more advanced stage of toxicity may complain of color vision changes or paracentral scotomas. Advanced hydroxychloroquine toxicity presents as a bullseye maculopathy. Hydroxychloroquine or chloroquine ingestion can cause atrophy of the retinal pigment epithelium in the form of a bull’s eye maculopathy in cases of chronic use. Early detection of toxicity prior to the development of the bull’s eye is important, as loss of visual acuity is usually irreversible at that stage. Bull's-eye maculopathy has been associated with various macular diseases, most notably chloroquine and hydroxychloroquine maculopathy, cone dystrophy, and Stargardt disease Table 1. To our knowledge, bull's-eye maculopathy associated with chronic macular holes has not been previously reported.

    Mar 15, 2019 In 1962, J Lawton Smith coined the term bull's eye maculopathy, regarded as the classic finding of macular toxicity. Physicians who prescribe chloroquine and hydroxychloroquine may not be fully aware of the potential ophthalmic implications. 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 of central vision, peripheral vision, and night vision. These findings were consistent with bull's eye maculopathy, a classic feature of advanced hydroxychloroquine toxicity. 3 months after medication was stopped, the patient's visual acuity had remained stable, and no other complaints were reported.
