Intraocular pressure values in treated and fellow eyes.
Notes: Each column represents the mean (plus or minus the standard deviation) intraocular pressure value at each time point; *P < 0.05; ***P < 0.001, for each time point versus baseline, as measured by paired t-test using Bonferroni correction after repeated analysis of variance; ^###P < 0.001, for treated eye versus fellow eye at each time point, as measured by unpaired t-test using Bonferroni correction after repeated analysis of variance.

Percentage reduction of intraocular pressure in the treated eyes at each time point.
Notes: Intraocular pressure reduction rates in the treated eyes are classified into four categories: >30%, >20%, >10%, ≤10%; closed circle (●) represents the mean plus or minus the standard deviation; no significant difference in distribution at all time points observed, as measured by chi-square test (P = 0.0859).

Change in intraocular pressure (IOP) compared with baseline in high, medium, and low groups.
Notes: The treated eyes were classified into the three groups based on their baseline IOP values (low: <13 mmHg; medium: 13–16 mmHg; high: ≥16 mmHg); each column represents the mean (plus or minus the standard deviation) of IOP values at each time point; **P < 0.01; ***P < 0.001, each time point versus baseline, as measured by unpaired t-test using Bonferroni correction after repeated analysis of variance.
