Spectral-Domain Optical Coherence Tomography as a Screening Technique for Chloroquine and Hydroxychloroquine Retinal Toxicity

Abstract

Significant retinal thinning occurred 1.0 mm, but not 0.5 mm, from the foveal center in patients with early and late chloroquine or hydroxychloroquine toxicity. Measuring retinal thickness 1.0 mm from the foveal center in patients receiving these medications may help screen for early toxicity.
