Association between Serum Total Bilirubin Level and Patients with Primary Open-Angle Glaucoma in China: A Cross-Sectional, Case-Control Study

Table 4

Comparison of serum bilirubin levels between subgroups of POAG group in female subgroup.

Factors	Mild POAG ()	Moderate POAG ()	Severe POAG ()	value
Age				0.489
VCDR				<0.001
IOP (mm)				0.989
ACD (mm)				0.613
AL (mm)				0.292
CCT (mm)				0.323
MD (dB)				<0.001
MS (dB)				<0.001
TBIL (μmol/L)				0.580
DBIL (μmol/L)				0.454
ALT (U/L)				0.072
AST (U/L)				0.183
GGT (U/L)				0.341

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.
