  1. P < 0.05 means the parameters changed significantly, as evaluated by the One-Way Repeated measures ANOVA (data consistence with homogeneity of variance).
  2. P value: Pairwise comparison of parameters from T0 toT1; P’ value: Pairwise comparison of parameters from T0 to T2;
  3. IOP: Intraocular pressure; SCAR-n: The nasal cross-sectional area of Schlemm’s canal. SCAR-t: The temporal cross-sectional area of Schlemm’s canal. PD: Pupil diameter; MAP: Mean arterial pressure; MOPP: Mean ocular perfusion pressure.
