目的：探讨小梁切除术中应用改良可调整缝线的方法和疗效。 方法：对65例70眼原发性急性闭角型青光眼患者行小梁切除术，术中对巩膜瓣采用改良可调整缝线缝合。观察术后眼压、前房、滤过泡、可调整缝线松脱等情况。 结果：所有患者随访时间6～24(平均11)mo。可拆除缝线拆线时间1～14（平均7.4）d。拆线前眼压13.30～2846(平均16.86)mmHg，拆线后眼压8.40～16.57(平均10.50)mmHg，二者差异有统计学意义(P<0.05)。70眼均无拆线并发症和滤过泡渗漏。术后70眼中Ⅰ度浅前房3眼，Ⅱ度浅前房2眼，浅前房发生率7%。70眼末次随访眼压9.00～16.80(平均11.45)mmHg，70眼形成扁平滤过泡55眼，微小囊样滤过泡15眼，功能性滤过泡100%。 结论：改良可调整缝线在小梁切除术中安全、术后有效，可有效控制术后房水滤过水平，有利于远期眼压的控制和功能滤过泡的形成。

AIM:To discuss the method and effect of application of modified adjustable suture in trabeculectomy. METHODS:Trabeculectomy were done in 65 cases (70 eyes) of primary acute angle-closure glaucoma.Modified adjustable suture was used in scleral flap intraoperatively. Postoperative intraocular pressures, anterior chamber, filtering bleb, condition of adjustable suture were observed. RESULTS: All patients were followed up for 6-24 months (average 11 months). The time of taking out stitches ranged from 1 to 14 days (average 7.4 days). The intraocular pressure before taking out stitches was 13.30-28.46 (average 16.86) mmHg, after was 8.40-16.57 (average 10.50) mmHg, there was statistical significant difference (P<0.05). There were no complications after taking out stitches and filtering bleb leaking in 70 eyes. Postoperative shallow anterior chamber ofⅠdegree was in 3 eyes,Ⅱ degree in 2 eyes, the shallow anterior chamber rate was 7%. The intraocular pressure of final follow-up was 9.00-16.80 (average 11.45)mmHg in 70 eyes, flat filtering bleb in 55 eyes, tiny cystic filtering bleb in 15 eyes, functional filtering bleb 100%. CONCLUSION: Modified adjustable suture is safe in trabeculectomy and effective postoperatively, which can effectively control the aqueous filtration level and be benefit for the long-term intraocular pressure controlling and functional filtering bleb formation.
