    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 patterns in various stages of hydroxychloroquine retinopathy. Classic bull’s-eye maculopathy appearance A. As the RPE atrophies, the FAF intensity in the pericentral macula changes to a mottled, or speckled appearance B, and eventually coalesces into dark areas of absence of FAF signal once the cells have died C. At right, FAF image shows large soft drusen associated with increased fundus autofluorescence in a patchy FAF pattern. There are also more defined areas of hyper-AF corresponding to mixed drusen in a focal increased pattern superior and inferior to the fovea. This is especially true in moderate and later stages of hydroxychloroquine. 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.

    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.

Plaquenil Hydrochloroquine or Aralen Chloroquine • Annual screening after 5 years of use **Interesting, The Royal College of Ophthalmologists in Great Britain does NOT recommend routine screening for toxicity with antimalarial drug use. In the present day, the less toxic HCQ is used instead of chloroquine. The American Academy of Ophthalmology revised the screening guidelines in 2011 to include spectral domain-optical coherence tomography SD-OCT, fundus autofluorescence FAF, and multifocal ERG mfERG when available to assess the macula in patients taking HCQ.
