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 2−5 min were studied. Conjunctival wound closure of all eyes was with the anchoring corneal suture technique using a 9−0 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 mmHg 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. Twenty eyes (30.3%) had qualified success postoperatively. Eight eyes (12.1%) had early wound leakage that resolved with conservative treatment. Three eyes (4.5%) required surgical repair. One eye (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.
