En face image-based classification of diabetic macular edema using swept source optical coherence tomography

Abstract This retrospective study was performed to classify diabetic macular edema (DME) based on the localization and area of the fluid and to investigate the relationship of the classification with visual acuity (VA). The fluid was visualized using en face optical coherence tomography (OCT) images...
