    This eye toxicity limits long-term use of the drugs. The risk of toxicity is low for individuals without complicating conditions during the first 5 years of treatment using less than 6.5 mg/kg/day of hydroxychloroquine or 3 mg/kg/day of chloroquine, and/or cumulative doses of less than 1000 gram and 460 gram (total dose), respectively.

    Retinal photograph showing classic “bull’s eye” retinopathy of hydroxychloroquine toxicity, which represents atrophy of the retinal pigment epithelium. This is a relatively late change, and good screening can detect toxicity before any bull’s eye is visible. And screening tests, but that screening begins after one year of therapy for all patients on chloroquine. Screening may be best incorporated into the hospital eye service via virtual clinics. The results of screening should be communicated back to the prescribing doctor, patient and GP as normal, possible or definite hydroxychloroquine retinopathy. Hydroxychloroquine Plaquenil, Sanofi-Aventis remains widely used in the treatment of various rheumatologic disorders. A small percentage of patients exposed to hydroxychloroquine will develop irreversible, and potentially progressive, retinal toxicity for which no effective treatment exists.

    The earliest signs of toxicity include bilateral paracentral visual field changes (best detected with a red test object) and a subtle granular depigmentation of the paracentral RPE. Some physicians suggest that lean body weight is more accurate when calculating daily dosage.

    In 2016, with new scientific data, the American Academy of Ophthalmology revised their screening recommendations for patients on chloroquine for longer than 1 year 5. The two most important risk factors for retinopathy are the duration of chloroquine treatment and a daily dose of chloroquine 2.3 mg/kg of the patient's actual body weight. Background. The American Academy of Ophthalmology recommendations for screening of chloroquine CQ and hydroxychloroquine HCQ retinopathy were published in 2002, but improved screening tools and new knowledge about the prevalence of toxicity have appeared in the ensuing years. 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. This article focuses upon hydroxychloroquine retinopathy. Disease
