Enhanced Physiological Stress Response in Patients with Normal Tension Glaucoma during Hypoxia

Figure 6

Overview of changes in serum levels of ET-1. ET-1 increased significantly during hypoxia in patients with NTG and in age-matched healthy controls. ET-1 levels remained high during recovery, creating a significant difference between baseline ET-1 levels and recovery in both groups (statistics: RM one-way ANOVA with Tukey’s multiple comparisons test).
