Figure 1. Risk of Blebitis, Hypotony, and Long-Term Endophthalmitis in the Collaborative Initial Glaucoma Treatment Study (CIGTS) Initial Trabeculectomy Cohort.

Figure 1

Kaplan-Meier analysis was used to calculate the probability of blebitis, hypotony and endophthalmitis during 5 years of follow-up. Based on 8 documented cases, the probability of blebitis (upper) during 5 years of follow-up was 0.015. The probability of hypotony (middle) based on 4 documented cases was 0.015; one of these patients was noted to exhibit hypotony maculopathy. Finally, three patients in the CIGTS initial trabeculectomy cohort were noted as having endophthalmitis, resulting in a 5-year Kaplan-Meier probability of endophthalmitis of 0.011 (lower). As described in the text, the diagnoses in two of these patients were presumed based on requirement of hospitalization, though the route of antibiotic administration is unclear. Excluding these two patients, the 5-year probability of endophthalmitis is 0.004.
