摘　　要：目的探讨不同大小切口的以穹隆为基底的结膜瓣,对小梁切除术后功能性滤过泡形成的影响。方法选择于我院施行小梁切除术的患者62名68只眼,依据穹隆为基底的“L”形切口结膜瓣的大小不同随机分为三组,A组结膜瓣切口为5mm×10mm,B组结膜瓣切口5mm×7mm,C组为A组基础上辅以角膜缘连续缝合。对术后功能泸过泡进行密切观察随诊,干预治疗,比较三种方法对眼压控制的效果。结果术后滤过道瘢痕形成A、C二组为0,B组31.81%;术后早期滤过过强A组30.40%>B组9.0%>C组8.70%。术后稳定期功能性滤过泡的保存率C组91.30%>A组86.96%>B组63.64%。结论以角膜缘连续缝合的以穹隆为基底的大切口结膜瓣联合调整缝线术可以提高小梁切除术后功能性滤过泡形成率。Objective To assess the outcome of preservation of the filtration bleb in eyes undergoing different incision of conjunctiva flap in trabeculectomy, Methods Choosed 68 eyes of 62 cases of primary angle-closure glaucoma were randomly divided into 3 groups. A group：23 eyes underwent large size of 5mm×10mm：B group：22eyes enderwent normal size of 5mm×7mm conjunctiva flap; C group：23 eyes underwent large size of 5mm×10mm conjunctiva flap with corneal limbal running suture, We observed the outcome of preservation of the filtration bleb in eyes and resolution of the blebassociated complication Evaluation effect of intraocular pressure in 3 groups, Results The drainage channel scar only outcomed in 7 eyes （31.81%） of B group; large filterability during early postoperative outcomed in 7 eyes （30.40%） of A group, outcomed in 2 eyes （9.09%） of B group, outcomed in 2 eyes （8.70%） of C group, In stable postoperative phase, the preservation of the bleb in eyes A group （30.40%）〉B group （9,0%） 〉C group （8.70%）, Conclusions The preservation of the filtration bleb in eyes undergoing large incision of conjunctiva flap with corneal limbal running suture in trabeculectomy often provides successful.
