EN-FACE OPTICAL COHERENCE TOMOGRAPHY IN PATIENTS WITH EPIRETINAL MEMBRANE: Intuitive Method for Predicting Functional Outcomes

Purpose: To evaluate the correlation between en-face optical coherence tomography (OCT) parameters and functional outcomes before and after idiopathic epiretinal membrane (ERM) surgery. Methods: This retrospective cohort study involved 80 eyes from 80 patients who underwent surgery for idiopathic ERM. Best-corrected visual acuity, metamorphopsia assessment (M-score), and OCT were assessed before surgery and six months after. The adhesive zone (A-zone) and retinal fold, a novel en-face OCT parameter reflecting inner retinal layer changes, were evaluated. Correlations between the area of A-zone and the number of retinal folds on en-face OCT images and other B-scan OCT parameters were evaluated regarding visual outcomes before and after ERM surgery. Results: The defect size of the ellipsoid zone, interdigitation zone, and external limiting membrane were significantly correlated with preoperative and postoperative 6-month best-corrected visual acuity (all P
