Survival Rates of OAGV and CAGV. a Survival curves for complete success (IOP control without glaucoma medications) of OAGV vs. CAGV were significantly different (p = 0.0004) by Log-rank (Mantel Cox) test. Survival rate for OAGV was 100% at 1-year and 80% with 95% CI [20, 97]. In contrast, survival rates for CAGV was 13% with 95% CI [2, 33] at 1-year and 0% at 2-years. b Survival curves for qualified success of OAGV vs. CAGV were also significantly different (0.04). Survival rate for OAGV was 100% at 1 and 2-years. Survival rates for CAGV was 63% with 95% CI [35, 82] at 1-year, 38% with 95% CI [16, 60] at 2-years, and 28% with 95% CI [8, 52] at 6-years
