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. The independent Student -test and chi-squared test were used.
