    Pattern of Retinopathy: Although the locus of toxic damage is parafoveal in many eyes, Asian patients often show an extramacular pattern of damage. Dose: We recommend a maximum daily HCQ use of 5.0 mg/kg real weight, which correlates better with risk than ideal weight.

    In the 1940's chloroquine and related antimalarials were subjected to extensive pharmacologic and clinical investigations.1-6 However, the dosage of chloroquine required to treat an acute attack of malaria or for prolonged suppressive therapy was small in comparison to the accumulated chloroquine. Chloroquine is a 4-aminoquinoline with antimalarial, anti-inflammatory, and potential chemosensitization and radiosensitization activities. Although the mechanism is not well understood, chloroquine is shown to inhibit the parasitic enzyme heme polymerase that converts the toxic heme into non-toxic hemazoin, thereby resulting in the accumulation of toxic heme within the parasite. Abstract. Background The American Academy of Ophthalmology recommendations on screening for chloroquine CQ and hydroxychloroquine HCQ retinopathy are revised in light of new information about the prevalence of toxicity, risk factors, fundus distribution, and effectiveness of screening tools.

    Risk of Toxicity: The risk of toxicity is dependent on daily dose and duration of use. There are no similar demographic data for CQ, but dose comparisons in older literature suggest using 2.3 mg/kg real weight.

    Jan 05, 2020 Disease Entity. 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. Chloroquine CQ is used to prevent and treat malaria and amebiasis,1 while hydroxychloroquine HCQ, a less toxic metabolite of chloroquine, is used to treat rheumatic diseases such as systemic lupus erythematosus SLE, rheumatoid arthritis RA, juvenile idiopathic arthritis JIA and Sjogren's syndrome.2 Both medications can cause corneal deposits, posterior subcapsular lens opacity. Oct 01, 2018 Chloroquine phosphate tablets should not be used in these conditions unless the benefit to the patient outweighs the potential risks. Usage in Pregnancy Usage of Chloroquine during pregnancy should be avoided except in the prophylaxis or treatment of malaria when the benefit outweighs the potential risk to the fetus.
