AIM: To assess the safety and efficacy of fornix-based trabeculectomy with the 'anchoring' corneal suture technique in Chinese patients. METHODS: A retrospective non-comparative case series of 66 eyes of 63 Chinese patients who underwent fornix-based trabeculectomy combined with intraoperative mitomycin C (MMC) 0.4 mg/ml for 25 minutes were studied. Conjunctival wound closure of all eyes was with the anchoring corneal suture technique using a 90-nylon suture to prevent leakage at the corneolimbal interface. The success rate, with or without anti-glaucoma medication, the complication rate and the longevity of the drainage blebs were analyzed. RESULTS: At a mean follow-up period of 447.36 ± 337.98 days, the mean intraocular pressure decreased from 26.83 ± 7.90 to 17.74 ± 8.74 mmHg (p < 0.001). The mean glaucoma medication decreased from 2.95 ± 0.98 preoperatively to 1.23 ± 1.41 postoperatively (p < 0.001). Thirty-one eyes (47.0%) required no anti-glaucoma medication postoperatively; 20 (30.3%) had qualified success postoperatively; eight (12.1%) had early wound leakage that resolved with conservative treatment; three (4.5%) required surgical repair; and one (1.5%) had hypotonous maculopathy. No other major complications were encountered. CONCLUSION: Fornix-based trabeculectomy with adjunctive mitomycin C employing the anchoring corneal suture technique appears to be both safe and effective in Chinese patients.
