When taken at high doses and for long durations, hydroxychloroquine has been known to cause parafoveal retinal toxicity. This toxicity is often insidious, causing serious, irreversible visual deterioration if not detected early. How is plaquenil metabolized Chloroquine phosphate in myocardial infarction Chloroquine phosphate reef2reef Hydroxychloroquine hypersensitivity rash Fundus photo = bullseye= too late source webvision Patient 1 = Obvious Toxicity Is a 70 year old White female with previously diagnosed plaquenil toxicity. Stopped taking drug 7 years prior Vision loss continues to progress Wants to measure change from last exam with mfERG in 2002. Harbors deep seeded anger for old 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, 2incidence of HCQ retinopathy is estimated at 1 % after consumption of HCQ for 5 years is marked by paracentral and central scotoma and decreased color vision. Hydroxychloroquine HCQ retinopathy can result in permanent vision loss. In early stages of HCQ retinopathy, patients are usually asymptomatic with preservation of visual acuity. We aspire that our review, in conjunction with the American Academy of. • No single imaging platform can confirm the presence of hydroxychloroquine toxicity, but a combination of imaging tests can provide ample evidence for diagnosis. • Long-term use of hydroxychloroquine sulfate may result in parafoveal retinal toxicity.

Multiple commercially available imaging systems, including the fundus camera, the confocal scanning laser ophthalmoscope, and the ultra-widefield imaging device, are available to the. Clinical applications of fundus autofluorescence in retinal.. Hydroxychloroquine retinopathy A review of imaging. Early Plaquenil Toxicity Detected without Bull’s Eye.. 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 Is Not the Best Early Screen for Hydroxychloroquine Toxicity—Reply. These images were intended to remind ophthalmologists that. Our patient demonstrates the importance of using the new recommended screening tools for the detection of early hydroxychloroquine toxicity. 10-2 HVF, SD-OCT, autofluorescence, or mfERG might have detected the hydroxychloroquine retinal toxicity on the day of her presenting symptoms and possibly earlier, potentially limiting the amount of.
