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.

    Hydroxychloroquine, by decreasing TLR signaling, reduces the activation of dendritic cells thus mitigating the inflammatory process.

Hydroxychloroquine is also used for the prophylaxis of malaria in regions where chloroquine resistance is unlikely. Safety considerations. The studies reviewed here show that chloroquine/ hydroxychloroquine has in-vitro antiviral effects and anti-inflammatory properties that may be of interest in those viral infections associated with inflammation and/or immune activation. Before analysing the potential effects of a drug on a disease. Cytochrome P450 enzymes converts hydroxychloroquine into its active metabolite, desethyl hydroxychloroquine.6 The onset of action may take up to 4–6 weeks post-commencement of therapy, and it may take 3–6 months to achieve maximal clinical efficacy. The recommended maintenance dose of hydroxychloroquine is 200–400 mg daily.
