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. Hydroxychloroquine vs truvada Plaquenil eye exam coding Chloroquine online 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. And screening for hydroxychloroquine retinopathy should be given to all patients. GPP All patients should undergo 10-2 Humphrey visual fields testing using a white stimulus, followed by pupillary dilation and imaging with both spectral domain optical coherence tomography SD-OCT and widefield fundus autofluorescence FAF. B Hydroxychloroquine HCQ; Plaquenil, Sanofi, Bridgewater, NJ is an antimalarial agent that is also commonly used as a treatment for a variety of rheumatologic and dermatologic conditions, such as rheumatoid arthritis and systemic lupus erythematosus. 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.

The study findings revealed that when hydroxychloroquine was used at doses 5mg /kg, the risk of retinopathy was 1% in the first 5 yrs. 2% in 10 yrs. 20 % after 20 yrs. There was a dose response, such that those receiving doses greater that 5 mg / kg had the greatest risk of retinal toxicity. Thirty eyes with HCQ retinopathy were followed with SD-OCT after drug cessation. Findings before disruption of the parafoveal EZ included parafoveal outer nuclear layer ONL thinning, disruption of the parafoveal interdigitation zone, and reduced reflectivity of the parafoveal EZ. Jan 05, 2020 Hydroxychloroquine retinopathy is most influenced by daily dose and duration of use. Risk for toxicity is less with 5.0 mg/kg real weight/day for hydroxychloroquine and 2.3 mg/kg real weight/day for chloroquine. Patients are at low risk during the first 5 years of treatment.
