目的观察巩膜瓣可调整缝线在小梁切除术中的应用效果。方法对60例(80只眼)青光眼患者做常规的三角形巩膜瓣与小梁切除术,在巩膜瓣两侧做可调整缝线,术后观察眼压、前房深度、结膜滤过泡。当手术后前房形成稳定或眼压回升大于10 mm Hg时,拆除巩膜瓣可调整缝线。结果术后第1天全部前房形成良好,术后巩膜瓣可调整缝线2周内拆除,平均7 d,可调整缝线拆除后,结膜滤过泡明显增大。结论巩膜瓣可调整缝线能促进小梁切除术后早期前房的形成,有效预防术后浅前房发生,术后2周内拆线对眼压具有调节作用,提高青光眼小梁切除术的安全性。
Objective To observe the effect of scleral flap adjustable sutures in trabeculectomy. Methods Sixty eyes (80 eyes) of glaucoma were treated with conventional triangular scleral flap and trabeculectomy. Adjustable sutures were made on both sides of the scleral flap. Intraocular pressure, anterior chamber depth and conjunctival filtration were observed. Scleral flap removal adjusts for sutures when the formation of anterior chamber stabilizes or the intraocular pressure rises more than 10 mm Hg after surgery. Results All anterior chamber was well formed on the first postoperative day. The scleral flap could be removed within 2 weeks after operation, with an average of 7 days. After the suture was removed, conjunctival filtration bleb was significantly increased. Conclusions Scleral flap adjustable suture can promote the formation of early anterior chamber after trabeculectomy and prevent the occurrence of shallow anterior chamber postoperatively. Suture removal within 2 weeks after operation can regulate intraocular pressure and improve the effect of glaucoma trabeculectomy safety.
