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 2016 Plaquenil patient education Plaquenil help trans myelitis Where is sandoz plaquenil produced May 16, 2011 Hydroxychloroquine Plaquenil; HCQ has been an important and effective drug for the treatment of lupus erythematosus and related autoimmune and inflammatory diseases for half a century, although its potential to cause retinal damage continues to raise concern among rheumatologists and ophthalmologists. Apr 20, 2011 8. Kellner S, Weinitz S, Kellner U. Spectral domain optical coherence tomography detects early stages of chloroquine retinopathy similar to multifocal electroretinography, fundus autofluorescence and near-infrared autofluorescence. Br J Ophthalmol. 2009 Nov;93111444-7. 9. Lai TY, Ngai JW, Chan WM, Lam DS. 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.

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. Recommendations on Screening for Chloroquine and.. Retinal Physician - Hydroxychloroquine Maculopathy An.. Hydroxychloroquine retinopathy A review of imaging. SD Spectral Domain OCT With early Hydrochloroquine retinopathy, SD-OCT can detect outer layer retinal abnormalities Specifically, SD-OCT can detect loss of the perifoveal photoreceptor inner segment/outer segments line PIL At the macula, an ovoid appearance can appear described as “flying saucer” sign by Chen, et al18 ILM IPL OPL Today it is recommended that every single person on Plaquenil get a visual field 10-2 test, plus one of the three other highly sensitive screening tests the FAF fundus autofluorescence imaging, the SD-OCT spectral domain optical coherence, or the multifocal electroretinogram mfERG,” Thomas says. 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.
