  1. In multiple linear regression analysis, only parameters with highly significant correlations (min. p ≤ 0.01) with postoperative visual acuity and only patients with a closed MH (n = 164) were included. Macular hole indices were omitted due to multicollinearity/redundancy of the data. The aperture diameter and preoperative visual acuity were the strongest predictive factors for postoperative visual acuity. Abbreviations: CI confidence interval, MLD minimum linear diameter, BD base diameter; H max. Height, Ar area of MH, Cy area of pseudocysts, VA visual acuity, ns not significant; **: p ≤ 0.01; ***: p ≤ 0.001
