    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.

    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. Rheumatologists use hydroxychloroquine sulfate Plaquenil, Concordia Pharmaceuticals to treat autoimmune diseases, namely discoid or systemic lupus erythematosus, rheumatoid arthritis, Sjögren syndrome, and malaria. When taken at high doses and for long durations, hydroxychloroquine has been known to cause parafoveal retinal toxicity. 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

    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.

Hydroxychloroquine, sold under the brand name Plaquenil Sanofi-Aventis, is an antimalarial drug that has gained widespread use in treating various autoimmune diseases, including systemic lupus erythematosus and rheumatoid arthritis. 1 By some estimates, more than 150,000 patients are on long-term therapy with this medication in America alone. 2.

    The multifocal electroretinogram mfERG can provide objective corroboration for visual fields, and fundus autofluorescence FAF can show damage topographically. Modern screening should detect retinopathy before it is visible in the fundus. Toxicity Retinopathy is not reversible, and there is no present therapy. Recognition at an early stage. Fundus Autofluorescence FAF Early hydroxychloroquine toxicity can also be detected on autofluorescence as an increased ring of signal within the parafoveal and extramacular regions, which is indicative of photoreceptor dysfunction and RPE dysfunction. In patients with plaquenil-induced toxic maculopathy, the release of lysosome is abnormal and this produces an imbalance between lipofuscin formation and disposal. Structural Damage to the Eye. Hydroxychloroquine plaquenil and chloroquine have an affinity for pigmented ocular structures and binds to melanin in the RPE

    Efflux of chloroquine from Plasmodium falciparum mechanism. Chloroquine-resistant Plasmodium falciparum accumulate significantly less chloroquine than susceptible parasites, and this is thought to be the basis of their resistance. However, the reason for the lower accumulation of chloroquine was unknown. The resistant parasite has now been found to release chloroquine 40 to 50 times more rapidly than the susceptible parasite, although their initial.

    No Plasmodium falciparum Chloroquine Resistance.
