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. Plaquenil information sheet Will plaquenil cause weight gain Where to buy chloroquine phosphate Hydroxychloroquine and omeprazole A 57-year-old female presented to the Ophthalmology clinic at UIHC complaining bilateral central photopsias for the past two years. She suffered from Sjogren syndrome and inflammatory arthritis and was currently treated with prednisone and methotrexate. She was previously treated with hydroxychloroquine Plaquenil 200mg bid 6.5mg/kg for 10 years, which was stopped one year prior to. Although multifocal electroretinogram mfERG and fundus autofluorescence FAF are not currently primary tests used in the evaluation of Plaquenil retinal toxicity, they may be beneficial when the diagnosis or findings are enigmatic or an adjunct test is warranted. Figure 1 is an image of an ocular fundus using autofluorescence to designate an area of retinal damage. To detect chloroquine toxicity, the American Academy of Ophthalmology recommends performing fundus examinations, 10-2 automated visual fields, and at least one objective test multifocal electroretinography mfERG, fundus autofluorescence. 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.

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.

Fundus autofluorescence image of a 46-year-old woman with systemic lupus erythematosus who had taken chloroquine for 17 years at a dosage of 500 mg/d.
