目的: 探讨小梁切除术两种不同结膜瓣术后功能性滤过泡形成情况。

方法: 比较 372 例(372 只眼) 原发性青光眼不同结膜瓣小梁切除术术后功能性滤过泡形成情况, 其中以角巩缘为基底的结膜瓣 165 只眼, 以穹窿部为基底的结膜瓣 207 只眼。

结果: 术后 1 周对所有患者进行了观察, 3 个月时只有 127 只眼进行了随访。以角巩缘为基底的结膜瓣手术组术后 1 周滤过泡成功率为 83.03 %, 3 个月时为 78.69 %。以穹窿部为基底的结膜瓣手术组术后 1 周滤过泡成功率为 55.07 %, 3 个月时为 53.03 %。两组比较有明显差别。

结论: 本组研究发现, 传统的以角巩缘为基底的结膜瓣术后滤过泡成功率高于以穹窿部为基底的结膜瓣, 其术后降压效果相应亦较好。

Purpoes: To assess the success rate of the formation of functional filtration bleb in eyes undergoing different incision of conjunctiva flap after trabeculectomy.

Methods: To study the formation of functional filtration bleb after trabeculectomy, the result of trabeculectomy with the limbus based conjunctival flap in 165 eyes and the fornix based conjunctival flap in 207 eyes (372 eyes in 372 cases with primary glaucoma in total) was compared.

Results: All patients were observed after trabeculectomy in 1 week, but only 127 eyes were followed up in 3 months. In patients with trabeculectomy using the limbus based conjunctival flap, the success rate of the formation of the filtration bleb was 83.03 % in 1 week and 78.69 % in three months postoperatively, while in those using the fornix based conjunctival flap, the success rate was 55.07 % in 1 week and 53.03 % in 3 months. There was significant difference between the two groups in terms of the success rate of the formation of the filtration bleb.

Conclusions: The result showed that limbus based conjunctival flap was especially effective and had better postoperative intraocular pressure decline.
