METHODS： This was a cross-sectional study including all cases had undergone trabeculectomy with MMC 0.2 mg/mL for 3 min. Participants were recruited from the follow-up cases at Department of Ophthalmology, Tanta University in the period from August 2015 to August 2016. Full history taking and ophthalmological examination were performed. Intraocular pressure（IOP） was measured using Goldmann applanation tonometry and the history of prescribed postoperative antiglaucoma medications was recorded. Accordingly, the trabeculectomy blebs were divided clinically into successful blebs when the IOP post-operative was ≤18 mmHg without medications. Scanning examination of the filtering bleb using UBM examination was performed at the period from 2 to 36 mo after trabeculectomy（13.6±9.7 m o）. RESULTS： This study included 33 trabeculectomy filtering blebs of 25 patients（9 males and 16 females）. The mean age of patients was 53.2±14.2 y（range 25-71y）. We had 20 eyes with complete success, 9 eyes with qualified success, and 4 eyes with failure after trabeculectomy with MMC. The blebs were classified into successful blebs（IOP ≤18 mmHg without antiglaucoma medications）, others were classified into qualified successful and failed blebs. There was a significant correlation between certain UBM findings（intra-bleb reflectivity, draining sub-scleral tract, bleb height, and intrableb fluid cysts） and cases with different grades of clinical functional success（P〈0.01）.CONCLUSION： UBM is an objective tool in the functional assessment of the post-trabeculectomy filtering bleb through a significant correlation between certain UBM parameters and the different grades of clinical functional success.展开更多

The basic information was recorded, and the interval time between trabeculectomy and autologous conjunctival flap surgery as well as related risk factors, intraocular pressure（IOP）, anterior chamber depth（ACD） and best corrected visual acuity（BCVA） were analysed. Moreover, 41 patients who completed the 1-year follow up were analysed to determine the IOP and BCVA changes and long-term success rates.RESULTS： The 50 male and 56 female subjects（average age 39.13±17.96 y） included 47（44.34%） and 33（31.13%） cases of primary open angle and primary angle-closure glaucoma. The mean interval between trabeculectomy and repair surgery was 60.60±56.92（3-264）mo. The mean mitomycin（MMC） concentration during trabeculectomy was 0.27±0.04（0.12-0.4） mg/m L in the fornix-based conjunctival flap group（68 patients） and 0.28±0.04（0.20-0.33） mg/m L in the limbal-based conjunctival flap group（11 patients）. After bleb leakage, the patients＇ vision remained stable while the IOP decreased from 10.25±4.76（3-20.86） to 9.44±4.33（2-21） mm Hg（P〈0.01）. In the 41 analysed patients, the IOP was controlled at 15.68±5.11（7-40） mm Hg in the 1^（st） year after autologous conjunctival flap surgery and recurrence was not observed, for a long-term success rate of 100%. CONCLUSION： Autologous conjunctival flap repairing surgery is an effective technique for sealing filtering bleb leakages and controlling IOP postoperatively.展开更多
