Purpose: To analyze functional and morphological findings after surgery for idiopathic epiretinal macular membrane (IEMM). Materials and Methods: Twenty eyes of 20 patients affected by IEMM underwent 23-Gauge surgery. Morphological and functional examinations were assessed at baseline and at 30, 90, and 180 days after surgery. SD-OCT evaluated foveal morphology and thickness, photoreceptor inner/outer segment junction, and external limiting membrane. Functional assessment evaluated visual acuity, retinal sensitivity, and fixation patterns. Statistical analysis was performed with the Student’s t test and Pearson correlation test. Results: Mean central retinal thickness (CRT), visual acuity (VA), and retinal sensitivity (RS) at baseline were respectively 494.90 ± 38.73 µm, 0.55 ± 0.08 LogMAR, and 11.13±1.02; after surgery, at day 180, we observed a significant decrease in mean CRT to 326.90±32.68 µm, an increase in mean VA to 0.33 ± 0.05 LogMAR (p
