test and 1-way analysis of variance (ANOVA) were used. Data are expressed as . a for the difference between mild POAG and moderate POAG (1-way ANOVA with the LSD post hoc test). b for the difference between mild POAG and severe POAG (1-way ANOVA with the LSD post hoc test). c for the difference between moderate POAG and severe POAG (1-way ANOVA with the LSD post hoc test). VCDR: vertical cup/disc ratio; CCT: central corneal thickness; ACD: anterior chamber depth; AL: axial length; MD: mean deviation values for the visual field; MS: mean sensitivity values for the visual field; IOP: intraocular pressure; POAG: primary open-angle glaucoma; TBIL: total bilirubin; DBIL: direct bilirubin; AST: aspartate aminotransferase; ALT: cereal third transaminase; GGT: γ-glutamyl transpeptidase.
