Fornix-based trabeculectomy with Wise's suture technique in Chinese patients.

ABSTRACT

OBJECTIVE: To assess the safety and efficacy of fornix-based trabeculectomy with Wise's suture technique in Chinese subjects. DESIGN: A retrospective noncomparative case series. PARTICIPANTS: Forty-eight eyes of 44 Chinese subjects that underwent fornix-based trabeculectomy combined with intraoperative 0.4 mg/ml mitomycin-C for 3 to 5 minutes were studied. INTERVENTION Conjunctival wound closure of all eyes was with the Wise's technique using 9-0 nylon suture to prevent leakage at the corneolimbal interface. MAIN OUTCOME MEASURES: The success rate, with or without antiglaucoma medication, the complication rate, and the longevity of the drainage blebs were analyzed. RESULTS: At a mean follow-up period of 21.8 +/- 4.5 months, 75% (36 eyes) had postoperative intraocular pressure of 21 mmHg or less. Of these, 23 eyes (47.9%) required no antiglaucoma medication, 7 eyes (14.6%) required one medication, 3 eyes (6.3%) required two medications, and 3 eyes (6.3%) required three medications. Ten eyes (21%) had early wound leak. Two eyes (4.2%) required surgical repair. Two eyes (4%) had hypotonous maculopathy. No other major complications were encountered. CONCLUSIONS: Fornix-based trabeculectomy with adjunctive mitomycin-C using Wise's suture technique appears to be both safe and effective in Chinese subjects.
