Time Domain OCT in Hydroxychloroquine Plaquenil Toxicity. Time domain OCT does not have the resolution that spectral domain OCT has, making detection of hydroxychloroquine maculopathy by this modality less sensitive. Nevertheless, time domain OCT machines are more widely available, making it important to be able to recognize toxicity with. Main Outcome Measures: SD-OCT findings suggestive of HCQ retinopathy before parafoveal ellipsoid disruption. Retrospective clinical data review by the Boston Image Reading Center.

Plaquenil-Induced Toxic Maculopathy - Decision-Maker PLUS. Time Domain OCT in Hydroxychloroquine Plaquenil Toxicity.. Despite Plaquenil dosing recommendations, retinal toxicity.. Spectral-Domain Optical Coherence Tomography and Adaptive Optics may Detect Hydroxychloroquine Retinal Toxicity before Symptomatic Vision Loss Kimberly E. Stepien, MD, * Dennis P. Han, MD, Jonathan Schell, MD, Pooja Godara, MD, Jungtae Rha, PhD, and Joseph Carroll, PhD With Plaquenil Plaquenil is manufactured in only a 200 mg tablet The typical dosage is either 200 or 400 mg per day 200 mg daily puts anyone under 68 pounds at risk1 400 mg of Plaquenil daily puts anyone under 135 pounds at a higher risk for toxicity Therefore, 200mg of Plaquenil daily is going to be a safe dosage for virtually all adults13 We now know that bull’s-eye maculopathy is a late finding and may be associated with vision loss. Asians have a slightly different clinical presentation 3-4. Several recent studies have shown that instead of the classic perifoveal changes typical of hydroxychloroquine toxicity, Asians with retinal toxicity have a more peripheral pattern.
