Chloroquine can also induce cataract formation; however, no reports of hydroxychloroquine and cataract have been reported. This article focuses upon hydroxychloroquine retinopathy. Disease Chloroquine is a potent drug used for the treatment of various diseases, including malaria and a range of connective tissue disorders. Chloroquine retinopathy is an important complication that may appear even years after cessation of the drug, presenting with impaired visual acuity, central vision loss and progressive damage that could result in irreversible blindness. Tamoxifen is a retinal toxin in its own right, although most cases of tamoxifen retinopathy were reported early in the history of the drug when higher dosages were prescribed. 26 Our data indicate that chronic low-dosage administration of tamoxifen has an adverse synergism with hydroxychloroquine, and the effect is related to the cumulative dose.

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.

Mar 10, 2017 HCQ and chloroquine retinopathies, once symptomatic, are characterised by abnormalities of the retinal pigment epithelium, which are detectable clinically, and may later develop into the classic. The retinopathy is manifest as damage to the photoreceptors and subsequent degeneration of the retinal pigment epithelium RPE. This may produce a “Bull’s eye maculopathy” and central visual loss. Chloroquine and hydroxychloroquine both belong to the quinolone family and share similar clinical indications and side effects, including retinal toxicity. Chloroquine-induced retinal toxicity was first described in 1959 and the retinal toxic effects of hydroxychloroquine were later described in 1967 3, 4.
