摘　　要：目的探讨青光眼小梁切除术两种不同大小巩膜瓣术后功能性滤过泡成功率。方法比较339例（339只眼）原发性青光眼中2mm×2mm的小巩膜瓣149只眼，4mm×4mm的大巩膜瓣190只眼，小梁切除术后功能性滤过泡形成情况。结果小巩膜瓣手术组术后1周滤过泡成功率为82．55％，3个月时为55．36％。大巩膜瓣手术组术后1周滤过泡成功率为67．89％，3个月时为77．05％。两组比较差异有统计学意义。结论较大巩膜瓣青光眼小梁切除术后远期功能性滤过泡形成好于短小巩膜瓣且更安全，故应尽量采用较大巩膜瓣术式。Objective To assess the success rate of the formation of functional filtration bleb in eyes undergoing different incision of scleral flap in glaucoma trabeculectomy. Methods The forma- tion of functional filtration bleb after trabeculectomy was studied. Two different mode scleral flaps in trabeculectomy were performed in 339 cases （339 eyes） of primary glaucoma. The small scleral flap （2mm×2mm） was 149 eyes and the big scleral flap （4mm×4mm） was 190 eyes. Results All patients were observed after trabeculectomy in one week, but only 117 eyes were followed up in three months. In the small scleral flap, the success rate of the formation of the filtration bleb was 82.55% after trabeculectomy in one week, 55.36% in three months. In the big scleral flap, the suc- cess rate of the formation of the filtration bleb was 67.89% after trabeculectomy in one week, 77.05% in three months. There was significant difference between the two groups in terms of the success rate of the formation of the filtration bleb. Conclusions The clinical observation showed that the long-term effect was especially effective and safer for the big scleral flap. The trabeculecto- my with big scleral flap should be performed for primary glaucoma to improve the outcome.
