PURPOSE: To investigate the influence of preoperative antiglaucoma medications on trabeculectomy outcome. MATERIALS AND METHODS: Two hundred fifteen eyes, which underwent primary trabeculectomy, were retrospectively analyzed. The average follow-up was 39.8±30.3 months. The only cases of primary open-angle glaucoma, with or without pseudoexfoliation (PXF), were included. "Complete success" was defined as intraocular pressure (IOP) <18 mmHg without glaucoma medications, whereas relative success was defined as the same IOP target with medications. The influence of the preoperatively used glaucoma medications on surgical success was analyzed by univariate Pearson correlation and multivariate (ordinal) regression analysis. RESULTS: There were 118 male (54.9%) and 97 female (45.1%) patients with a mean age of 66.9±9.3 years. PXF glaucoma (PXFG) was present in 93 eyes (43.3%). In 33 patients (15.3%), diabetes mellitus (DM) was present. Complete success was achieved in 116 eyes (54%), relative success in 81 eyes (37.6%), and failure in 18 eyes (8.4%). Neither the total number nor the duration of glaucoma medications used before trabeculectomy was found to have any statistically significant influence on surgical success. In statistical analysis, a combination of topical beta-blocker and carbonic anhydrase inhibitor (BB+CAI) used before surgery was found to be associated with statistically better outcome, whereas the preoperative use of topical beta-blockers alone could have a negative influence on success. PXF was shown to be independently associated with trabeculectomy outcome on multivariate regression analysis. CONCLUSION: The glaucoma medications used preoperatively were not found to have any statistically significant negative influence on the trabeculectomy outcome and use of the combined BB+CAI preparation could have a positive influence, whereas the use of topical beta-blockers alone could have a negative influence on success, although not statistically significant. The presence of PXF was independently associated with a better surgical outcome.
