Newer studies have preferred practice protocols be changed to using spectral-domain OCT technology as the main screening device for detection of early retinal changes in plaquenil toxicity. The patient reported that she was in reasonably good health despite a long-term history of lupus. Hydroxychloroquine accidental drug overdose Is hydroxychloroquine the same as plaquenil The Academy’s new guidelines represent “a paradigm shift from subjective to objective measures,” said Dr. Fung. “It’s a new algorithm, very much a new concept in Plaquenil screening.” Some points to consider Preferred screening methods. 10-2 visual fields, but not Amsler grids, are still acceptable for screening if read with. The main outcomes were toxicity as determined by characteristic visual field loss or retinal thinning and photoreceptor damage. They also examined risk factors and prevalence. 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.
