BACKGROUND AND OBJECTIVE: To show the morphologic changes on the foveal avascular zone (FAZ) in patients with epiretinal membrane (ERM) using optical coherence tomography angiography (OCTA) and to demonstrate the correlation between distortion of FAZ and features of the ERM PATIENTS AND METHODS: FAZ eccentricity index (longest diameter of FAZ/shortest diameter of FAZ) was measured in 52 patients with ERM and compared with 27 healthy subjects' values. The density of the ERM was quantified using a grading scale (0-3) on multicolor scanning laser images, and spectral-domain OCT characteristics of the eyes were assessed RESULTS: Of the 52 eyes with ERM, 31 eyes (59.61%) showed some foveal remodeling, including full (13.46%) or partial (30.76%) apparent vascularization of FAZ, presence of a vessel crossing the fovea (9.61%), and horizontal or vertical elongation of FAZ (5.76%). The mean FAZ eccentricity index was 0.84 ± 0.46 (range: 0.0-1.86) in eyes with ERM and 0.98 ± 0.07 (range: 0.96-1.02) in the control subjects, respectively (P = .02). There was a negative significant correlation between FAZ eccentricity index and central macular thickness (P = .04) CONCLUSIONS: Thickening of the central fovea leads to foveal remodeling in ERM eyes, and OCTA enables the visualization of architectural FAZ changes.
