Saliva drug test rx hydroxychloroquine false positive drug test Plaquenil dental contraindications Background/Aims Hydroxychloroquine HCQ retinopathy may result in severe and irreversible vision loss, emphasising the importance of screening and early detection. The purpose of this study is to report the novel finding of early optical coherence tomography OCT abnormalities due to HCQ toxicity that may develop in the setting of normal Humphrey visual field HVF testing. Methods Data from. The treatment for early toxicity usually requires stopping Plaquenil. Patients taking Plaquenil should have an early baseline assessment of visual acuity, macular appearance and central field sensitivity. The macular appearance and function should be checked at intervals of 6 to 12 months. With so much at stake, optometrists cannot afford to underestimate the importance of screening and early detection. Researchers recently reported on early optical coherence tomography OCT abnormalities due to HCQ toxicity that may develop through normal visual field VF testing. Chloroquine is now uncommonly used in favor of its derivative hydroxychloroquine. This article focuses upon hydroxychloroquine retinopathy. Chloroquine was originally used as an anti-malarial therapeutic.

We did not, however, observe any cases of HCQ retinopathy in which the visual field was normal. Expanded spectral domain-OCT findings in the early detection..

Novel Image Analysis Platform May Detect Early Signs of Retinal Toxicity Secondary to Hydroxychloroquine Use. Ellipsoid zone mapping, a new image visualization/analysis platform on optical coherence tomography, may be an effective screening tool to identify subtle retinal changes indicative of toxicity from hydroxychloroquine treatment, Cleveland Clinic research indicates. A multitude of tests are needed to detect the earliest possible signs of hydroxychloroquine toxicity, according to Andrew A. Moshfeghi, MD, MBA. we could document toxicity with OCT as well as.
