Abstract

Purpose: To evaluate and compare the results of different surgical methods for post-trabeculectomy BLEB REVISION at Labbafinejad Medical Center, Tehran-Iran, from 1999 to 2003.Methods: This study was conducted on all patients who underwent post-trabeculectomy BLEB REVISION due to hypotony [intraocular pressure (IOP) less than 6 mmHg] or bleb leakage. Surgical methods were: conjunctiva advancement. rotational conjunctiva flap and free conjunctiva graft. BLEB REVISION was performed in the cases of bleb leakageif the bleb hole was greater than 1mm or leakage could not be controlled within 1 to 2 weeks of conservative treatment. BLEB REVISION was performed in eyes with hypotony in cases with cataract development or progression or hypotony maculopathy or iridocomeal adhesion. Surgical success was defined as IOP between 6-21mmHg with a maximum of 2 topical antiglaucoma medications and discontinuation of leakage.Results: Twenty-seven eyes of 27 patients (17male, 10 female) with meanage of 37.8±15.2 years (9-37 years) were studied. Indication for surgery was bleb leakage in 22 cases (81.5%) and hypotonous maculopathy in 5 cases (18.5%). Mean IOP was 4.4±1.04mmHg preoperatively and 13.00±1.29mm Hg postoperatively. (P<0.001) Mean visual acuity was 0.9 LogMAR (20/160) before surgery and reached 0.6 LogMAR (20/80) after BLEB REVISION. (P<0.002) Mean cup/disc ratio was 0.7 preoperatively which remained unchanged postoperatively. CONJUNCTIVAL ADVANCEMENT was performed in 18 cases (success rate=72.2%). ROTATIONAL CONJUNCTIVAL FLAP in 6 cases (success rate=66.7%) and free conjunctiva graft in 3 cases (success rate=66.7%). (P=0.73) BLEB REVISION was repeated in 2 cases due to continuous leakage. Mitomycin-C (MMC) and 5-fluorouracilhad been used during primary trabeculectomy in 62% and 7.6% of cases. respectively. In 19.6% of cases surgery was done without using ant metabolites and usage of ant metabolites was unknown in 11%.The average time between primary trabeculectomy and bleb leakageor hypotonia was 17 monthsin cases with prior use of MMC and 52 months in the cases with no antimetabolite usage (P<0.05).Conclusion: Post-trabeculectomy BLEB REVISION using conjunctiva seems to be a successful method for control of leakage and prevention of complications of hypotony.
