Comparison of Time-Domain OCT and Fundus Photographic Assessments of Retinal Thickening in eyes with Diabetic Macular Edema.
Abstract Purpose: To explore the correlation between optical coherence tomography (OCT) and stereoscopic fundus photographs (FP) for the assessment of retinal thickening (RT) in diabetic macular edema (DME) within a clinical trial. Methods: OCT, FP and best-corrected visual acuity (VA) measurements were obtained in both eyes of 263 participants in a trial comparing two photocoagulation techniques for DME. Correlation coefficients (r) were calculated comparing RT measured by OCT, RT estimated from FP, and VA. Principal variables were centraler subfield retinal thickness (CSRT) obtained from the OCT fast macular map and DME severity assessed by a reading center using a 7-step ...Read Full Article
