Purpose: To evaluate the surgical results of epiretinal membranes with optical coherence tomography (OCT) images. Methods: Fifteen eyes with idiopathic epiretinal membranes were studied. Optical coherence tomography (OCT), fluorescein angiography (FAG) and visual acuity were examined preoperatively. After three port vitrectomy combined with cataract surgery were performed, visual acuity and OCT were examined at postoperative 1 month, 3 months, 6 months. For statistical analysis, macular thickness was measured in OCT images and visual acuity was converted to logarithm of the minimum angle of resolution (log MAR). Results: Mean preoperative visual acuity was 20/48, and mean postoperative visual acuity at 6 months was 20/25. Postoperative visual acuity improved significantly (p < 0.0001). Mean preoperative macular thickness (444.977.9 µm) was reduced significantly at postoperative 6 months (33680.3 µm, p = 0.003). There were significant correlation between preoperative macular thickness and postoperative visual acuity at 6 months (regression coefficient = 0.53, p = 0.04). The eyes that had leakage of fluorescein preoperatively had worse postoperative visual acuity (p = 0.03), and had more macular thickness postoperatively (p=0.01). Conclusion: Preoperative macular thickness of idiopathic epiretinal membranes obtained by OCT and FAG were useful to evaluate postoperative visual acuity.
