    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.

    FUNDUS AUTOFLUORESCENCE FINDINGS IN EARLY CHLOROQUINE MACULOPATHY. Background/Purpose Toxic maculopathy is a rare but severe complication of chloroquine intake. Although the phenotype of established maculopathy was analyzed in detail, few data exist on the ophthalmologic findings in the early stage. 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. Chloroquine CQ and hydroxychloroquine Plaquenil HCQ have been used for many years, initially for the treatment of malaria but now more commonly for the treatment of inflammatory diseases such as rheumatoid arthritis and lupus 1. It is now considered for new disease applications in diabetes, heart disease and adjunct cancer therapies 2.

    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.

  6. The American Academy of Ophthalmology released an updated set of screening recommendations for hydroxychloroquine Plaquenil and chloroquine to account for the many studies that have shown the effects of these medications on the retina 1. It succinctly makes the case for screening, and

    Many systemic medications may cause retinal toxicity. One such commonly used medication for dermatologic and rheumatologic inflammatory conditions is hydroxychloroquine Plaquenil, a chloroquine derivative. It is used to treat many diseases including malaria, rheumatoid arthritis and systemic lupus erythematosus. 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. Hydroxychloroquine HCQ has been used for therapy of rheumatologic disorders since the 1950s. Ocular toxicity associated with HCQ use was initially described in the 1960s 1, 2. The incidence of HCQ retinopathy is estimated at 1 % after consumption of HCQ for 5 years 3.

    Chloroquine is a potent inhibitor of SARS coronavirus. Apart from the probable role of chloroquine on SARS-CoV replication, the mechanisms of action of chloroquine on SARS-CoV are not fully understood. Previous studies have suggested the elevation of pH as a mechanism by which chloroquine reduces the transduction of SARS-CoV pseudotype viruses 17,18.
