Multimodal Imaging in Plaquenil Toxicity. Recommendations on Screening for Chloroquine and Hydroxychloroquine.. Aug 30, 2011 Although hydroxychloroquine retinal toxicity is thought to be rare, recent studies suggest it may have a higher prevalence than previously recognized. A large study examining patients with more than 5 years of HCQ use were evaluated with 10-2 visual fields or spectral-domain optical coherence tomography SD OCT. Objective To determine whether early toxic effects from hydroxychloroquine HCQ could be detected by spectral-domain optical coherence tomography SD-OCT before symtomatic visual loss occured.
