Objective This study aimed to evaluate the role of ultrasound biomicroscopy (UBM) in assessing uneventful trabeculectomy parameters. Background The recent development of the UBM device has made it possible to observe the detailed structure of the anterior segment of the eye with a noninvasive procedure. Patients and methods In this prospective cohort study, an analysis of UBM scanning of 30 glaucomatous eyes of 30 patients, any age, both sexes, after 1 month from uneventful subscleral trabeculectomy operation was done. Results There was a negative significant correlation between bleb size (r = 0.905, P < 0.001) and intraocular pressure (IOP). There was an insignificant correlation at anterior chamber depth and IOP (P = 0.193). There was a positive significant correlation at bleb reflectivity and IOP (r = 0.836, P < 0.001). Multiple regression analysis showed that both bleb size and reflectivity affect IOP, but anterior chamber depth does not. Conclusion UBM is a good predictor of the anatomical patency of surgically created passage in post-trabeculectomy patients and well correlated with IOP.
