方法：对114例114眼原发性闭角型青光眼行小梁切除改进术，术中剥离巩膜瓣进入透明角膜1mm，并在巩膜瓣下注入玻璃酸钠形成前房。术后观察眼压、前房、滤过泡、视力及并发症发生情况，术后随访1～6mo。

结果：术后无持续性浅前房发生； 眼压控制在理想范围； 均可形成功能性滤过泡； 视力术后与术前有明显差异。

结论：青光眼小梁切除术的改进能很好的控制眼压，能减少并发症的发生，术式简单易行，效果稳定可靠，手术成功率高，是理想的术式选择。

METHODS: The modified trabeculectomy was performed on 114 cases(114 eyes)with primary angle-closure glaucoma. Lamellar sclera incision extended 1mm into clear corneal. Sodium hyaluronate was injected under sleral flap to deepen anterior chamber. Intraocular pressure(IOP), anterior chamber depth, filtering blebs, vision and complications were observed. The follow-up period ranged from 1 to 6 months.

RESULTS:Shallow anterior chamber was not occurred postoperatively. IOP was controlled in an ideal range. Functional blebs could form. Postoperative and preoperative visual acuity was significantly different.

CONCLUSION: IOP can be controlled effectively and postoperative complications were decreased after performed modified trabeculectomy. Modified trabeculectomy is easy, safe and effective, and has a high successful rate. It's a satisfactory surgery for primary angle-close glaucoma.
