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.
