摘　　要：目的探讨小梁切除术中改良巩膜瓣的制作方法,观察术后巩膜瓣的大小及缝合与房水滤过量和滤过泡形成的关系。方法对11例(20眼)不同类型的青光眼行小梁切除,术中制作4mm×6mm巩膜瓣,巩膜瓣的后缘与巩膜床间作3针跨度为4mm的闭合式缝合,并形成前房,观察术后早期房水滤过量和滤过泡的形成。结果术后随访半年,术后末次随访平均眼压(8.53±2.55)mmHg,与术前平均眼压(24.9±15.36)mmHg比较,差异有统计学意义(t=4.889,P=0.0001)。滤过泡:7d内Ⅰ型15眼,7d后～半年Ⅰ型13眼。术后均无前房形成迟缓。结论小梁切除术中大巩膜瓣的制作及闭合式缝线技术,术后早期前房自然恢复快,功能性滤过泡形成早,眼压控制效果明显。Objective To observe the Clinical effect of big sclera flap on the trabeculectomy. Methods 11 cases （ 20 eyes） of glaucoma accepted the trabeculectomy with big sclera flap （4 × 6 mm）, and the sclera flap was sutured by three needles （span 4 mm）. Then the anterior chamber was shaped. Results The postoperative follow-up period was six months. There was significant statistical difference between preoperative and postoperative IOPs （8.53±2.55 mmHg VS 24.9 ±15.36 mmHg） （t =4. 889,P = 0.0001）.Filtering bleb：l 5 eyes of Ⅰ type in 7 days, 13 eyes of Ⅰ type in six months. All Cases had normal anterior chamber. Conclusions The trabeculectomy with big sclera flap can effectively accommodate IOP,reduce the occurrent of postoperative shallow anterior chamber.
