Purpose: To study the role of ultrasound biomicroscopy (UBM) in assessment of the bleb function aft er trabeculectomy with Mitomycin C (MMC). Study design: Cross sectional study. Methods: Participants were recruited from the followup cases had undergone to trabeculectomy with MMC (0.2 mg/ml for 3 minutes) seen at Tanta University Eye Hospital in the period from Aug 2015 to Aug 2016. Full history taking and ophthalmological examination were performed. Intraocular pressure (IOP) was measured using Goldmann applanation tonometry and history of prescribed postoperative antiglaucoma medications was recorded. Accordingly, cases were divided into: (20 eyes) of complete success, (9 eyes) of qualifi ed success and (4 eyes) of functional failure. the fi ltering blebs were scanned by UBM, (VuMAXTM, Sonomed Escalon, USA), with 50 MHz transducer. Results: Th is study included 33 eyes of 25 patients (9 males and 16 females). Th e patients' age ranged from 25 to 71 years with mean 53.2 years �?± 14.2 SD, the mean recorded IOP was 14.4 mm/hg �?± 4.6 SD. UBM examination was performed 2 to 36 months aft er trabeculectomy with mean 13.6 months �?± 9.7 SD. Th ere was a signifi cant correlation between certain UBM fi ndings (the intra bleb refl ectivity, draining sub scleral tract, bleb height, and presence of intra-bleb fl uid cysts) and diff erent grades of clinical functional success (P < 0.01). Conclusion: UBM is a useful objective tool in the assessment of the post trabeculectomy fi ltering bleb as the study showed a signifi cant correlation between certain UBM parameters and the diff erent grades of clinical success.
