Official Title: Assessment of Retinal Layers and Visual Rehabilitation After Epiretinal Membrane Removal
Brief Summary: The purpose of this study is to evaluate the changes in visual acuity, metamorphopsia, and thickness of retinal layers after epiretinal membrane removal and to investigate factors associated with visual function.
Detailed Summary: Eyes with idiopathic Epiretinal Membrane Removal (ERM) scheduled to underwent ERM removal were included. Changes in visual acuity, metamorphopsia score (M-score) using M-chart, and parafoveal thickness of each retinal layer were evaluated preoperatively and at 2-month and 6-month postoperative follow-up visits. Factors associated with visual acuity and M-score were investigated.

Current Primary Outcome:
- Postoperative changes in visual acuity [ Time Frame: preop, 2-month postop, 6-months postop ]Changes in visual acuity (Early treatment diabetic retinopathy study score)was evaluated preoperatively and at 2-month and 6-month postoperative follow-up visits.
- Postoperative changes in metamorphopsia [ Time Frame: preop, 2 months postop, 6 months postop ]Changes in metamorphopsia score (M-score) was measured using M-chart and evaluated preoperatively and at 2-month and 6-month postoperative follow-up visits.
- Postoperative parafoveal thickness of each retinal layer [ Time Frame: preop, 2 months postop, 6 months postop ]Changes in parafoveal thickness of each retinal layer was evaluated based on spectral domain optical coherence tomography images
Original Primary Outcome: Same as current
