Abstract
A retrospective consecutive case series study was conducted Eightyfour eyes of 79 patients who had undergone primary trabeculectomy were included Surgical success was defined as IOP ≤15 mmHg and a 20 reduction in IOP without glaucoma medication and without additional glaucoma surgery at 1 year after trabeculectomy The subjects were classified into two groups according to whether surgery was successful or unsuccessful Filtering blebs were examined using sweptsource threedimensional anterior segment optical coherence tomography and evaluated for the following quantitative parameters maximum bleb height maximum bleb wall thickness and ratio of hyporeflective space of the bleb wallSixtysix eyes were determined to be successful and 18 eyes unsuccessful Univariate analysis showed significant differences between the two groups regarding bleb height P 0001 bleb wall thickness P = 0011 and ratio of hyporeflective space of the bleb wall P = 0002 Multivariate logistic regression analysis confirmed that the bleb height was significantly associated with success in trabeculectomy odds ratio 13996 95 confidence interval 1184–165420 P = 0036
