  1. † Wilcoxon signed-rank test.
  2. ‡ McNemar test.
  3. # Exact McNemar test.
  4. Values for continuous variables are expressed as mean ± standard deviation (SD), and categorical variables are presented as n (% of eyes). P-values were calculated using: Wilcoxon signed-rank test (†) for continuous data, McNemar test (‡) for paired categorical data, and exact McNemar test (#) for binary outcomes with zero baseline occurrence. Percentages are calculated based on the total number of eyes (n = 124).
