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
