OBJECTIVE: To determine the risk factors for late-onset infection following glaucoma filtration surgery. METHODS: The authors performed a case-control study comparing 131 cases of late-onset infection collected from 27 surgeons at ten centers, with 500 controls matched for date of surgery and surgeon. The criterion for the presence of infection was severe anterior chamber ration occurring later than four weeks after surgery. An opaque bleb and positive culture results were not required for diagnosis. Risk factors were identified by univariate and multivariate logistic regression analyses. RESULTS: Some of the risk factors that were statistically significant in the multivariate model after adjusting for age, race, and sex were: (1) performance of a full-thickness rather than a guarded procedure (risk ratio (RR), 13.1; 95% confidence interval (CI), 2.12-80.9); (2) filtration surgery performed without concurrent cataract surgery (RR, 2.25; 95% CI, 1.24-4.08); (3) use of mitomycin (RR, 2.48; 95% CI, 1.06-5.83); (4) intermittent use of antibiotics after surgery (RR, 2.10; 95% CI, 1.09-4.02); and (5) continuous use of antibiotics after surgery (RR, 5.94; 95% CI, 2.09-16.9). CONCLUSIONS: Eyes undergoing full-thickness procedures or filtration surgery without cataract extraction are at increased risk for late infection. Intraoperative mitomycin and episodic or continuous antibiotic use after the postoperative period are associated with an increased risk of infection.
