Medline. Nov 01, 2007 The toxicity associated with these drugs is bilateral bull's-eye maculopathy Figure 2. 13 The precise mechanism by which this occurs is unknown, but the drugs bind to melanin in the retinal pigment epithelium RPE and affect photoreceptor metabolism. In less advanced cases, the only findings may be loss of the foveal light reflex and nonspecific pigmentary abnormalities. Aug 29, 2014 Several risk factors may increase the likelihood of retinal toxicity from Plaquenil such as, age of greater than 60 years, daily dose more than 6.5 mg/kg; use of the drug more than 5 years, obesity, preexisting retinal disease and, renal or liver failure.

    “It’s a pretty rare thing.” Nevertheless, he urged doctors to master the Academy’s new guidelines, because the effects from chloroquine and hydroxychloroquine, when they do occur, are severe and often irreversible. “Plaquenil toxicity isn’t even in the top 10, or the top 100” if you’re looking at incidence, he said.

    Jan 05, 2020 Hydroxychloroquine Plaquenil and chloroquine cause ocular toxicity to various parts of the eye such as the cornea, ciliary body, and retina. Chloroquine can also induce cataract formation; however, no reports of hydroxychloroquine and cataract have been reported 1. Aug 06, 2014 In a separate study designed to compare chronically treated patients with and without ophthalmoscopic evidence of toxicity, significant thinning of the inner, outer and full thickness retina was observed in patients with clinically apparent retinal toxicity, whereas only selective thinning of the inner retina was detected in the group without fundus changes. 13 Once again, RNFL thinning was absent in patients with chronic HCQ exposure and no fundus changes; however, the group with fundus. Measurements of the macular GC-IPL thickness using SDOCT may therefore be useful in the early diagnosis and in monitoring the progression of retinal changes in patients receiving long-term HCQ therapy.
