  1. CDVA corrected distance visual acuity, logMAR logarithm of minimal of angle of resolution, PVD posterior vitreous detachment, SD standard deviation.
  2. P values less than the statistically significant level (= 0.05) are marked in bold.
  3. aValues are presented as means (SD) for continuous variables and percentages for categorical variables.
  4. bUnpaired t-tests for continuous variables and χ2 tests for categorical variables were used to test for statistical significance.
