  • ns = no significant differences.

  • Pearson’s χ2 or Fisher’s exact test for categorical data; analysis of variance (ANOVA) for continuous data with Duncan’s correction for multiple comparisons (p<0.05).

  • Patients in the senile sclerotic group were taking more vasoactive systemic medications in comparison with the other groups.

  • Patients in the myopic glaucoma group had smoked for less years in comparison with those in either the senile sclerotic or generalised cup enlargement groups.
