OBJECTIVE: To investigate the relationship between peripheral blood total bilirubin (TBIL) levels and the risk of primary open-angle glaucoma (POAG). METHODS: This study was a cross-sectional, case-control study design. Between April 2021 and January 2022, 198 POAG patients and 205 healthy subjects were recruited from the EENT Hospital of Fudan University. Their clinical information (intraocular pressure, central corneal thickness, vertical cup-disk ratios (VCDR), and axial length) and demographic data were collected. Serum levels of TBIL were measured in enzymes using a Roche C702 biochemical analyzer. The POAG subgroups were classified by gender and VCDR: mild (VCDR ≤ 0.64), moderate (VCDR ≤ 0.85), and severe (VCDR > 0.85). Univariate and multivariate logistic regression analyses were performed. RESULTS: The level of TBIL (11.58 ± 5.16 mol/L) in the POAG group was higher than that in the control group (10.18 ± 3.38 mol/L; < 0.05). In the male subgroup, TBIL was also significantly higher than in the normal control group; TBIL levels were lower in the mild subgroup (10.82 ± 4.48 mol/L), followed by the moderate subgroup (12.00 ± 5.55 mol/L) and the severe subgroup (14.47 ± 5.45 mol/L). The results of the multivariate logistic regression analysis showed that high TBIL levels were a risk factor for male POAG, at 1.126 (95% CI 1.009-1.256). Pearson's analysis revealed that TBIL was positively correlated with intraocular pressure ( = 0.134, = 0.012), VCDR ( = 0.142, = 0.046), anterior chamber depth ( = 0.190, = 0.014), and axial length ( = 0.179, = 0.019) in the patients. However, no statistical difference ( < 0.05) was observed in the female patients with POAG. CONCLUSION: The results showed that high levels of TBIL may be related to the pathogenesis of POAG and that the severity of the disease is positively correlated, especially in male patients.
