Table 1. Comparison of baseline characteristics among the study groups.

Values are presented as number or mean ± standard deviation.

LCD = lamina cribrosa depth; ILCD = increased LCD; NLCD = no LCD change; DLCD = decreased LCD; CCT = central corneal thickness; IOP = intraocular pressure; MD = mean deviation; VFI = visual field index.

^*p< 0.05 considered as statistically significant; ^†IOP reduction = (baseline IOP − follow up IOP) / baseline IOP × 100. Intergroup ANOVA testing was performed using the mean values. If p-values were <0.05, post hoc analysis (Tukey's test) was performed; ^‡p-value for the post hoc analysis of the ILCD and NLCD groups; ^§p-value for the post hoc analysis of the NLCD and DLCD groups; ^Πp-value for the post hoc analysis of the ILCD and DLCD groups.
