MHD Minimum hole diameter, ELM External limiting membrane, EZ Ellipsoid zone, BCVA Best corrected visual acuity; *, For preoperative BCVA, preoperative MHD, and postoperative BCVA, P-values were determined by ANOVA. For MH closure, ELM restoration, and EZ restoration, P-value determined by Chi-squared test
