Purpose: To investigate whether postoperative filtering bleb size affects the surgical outcome after trabeculectomy.
Results: A total of 145 eyes of 145 patients was included. The average observation period was 30.8 ± 10.9 months. During multivariate Cox regression analysis, a larger extent of filtering bleb revealed significantly low hazard ratios in both complete and surgical success (0.509 and 0.494, respectively); however, there was no significant relationship between bleb height and surgical outcome.
Conclusions: The extent of the filtering bleb was associated with surgical outcomes of trabeculectomy in glaucoma patients.
