With foveal depression	10 (52.6%)	4 (20%)	11 (52.4%)	0.047	0.048	1.000

DONFL: dissociated optic nerve fiber layer; ERM: epiretinal membrane; Group I: ERM removal without ILM peeling; Group II: ERM removal and whole-piece ILM peeling; Group III: ERM removal and ILM maculorrhexis; ILM: internal limiting membrane; SD-OCT: spectral-domain optical coherence tomography.
