Relationship between Oxidative Stress Biomarkers and Visual Field Progression in Patients with Primary Angle Closure Glaucoma

Figure 2

Kaplan-Meier survival curves showing the effects of oxidative stress-related factors on visual field progression, derived from Cox univariate analyses. Survival curves of the upper and lower subgroup were compared using log-rank tests. Factors analyzed included superoxide dismutase (SOD), total antioxidant status (TAS), and malondialdehyde (MDA).
