目的探讨巩膜瓣调整缝线在小梁切除术中预防浅前房的作用。方法将138只原发性闭角型青光眼分为两组:常规组68眼,行常规小梁切除术;调整缝线组70眼,行可调整缝线小梁切除术。观察两组术后浅前房形成及眼压等情况。结果术后浅前房:常规组25眼(36.76%);调整缝线组6眼(8.57%)(P﹤0.01)。术后眼压:随访6~12个月,常规组眼压控制﹤21mmHg者60眼(88.24%),调整缝线组眼压控制﹤21mmHg者62眼(88.57%),P﹥0.05。结论调整缝线小梁切除术后既可减少术后浅前房的发生,又可有效降低眼压,提高青光眼手术成功率。
Objective To investigate the effect of adjusting scleral flap suture in preventing trauma of shallow anterior chamber during trabeculectomy. Methods One hundred and thirty-eight primary angle-closure glaucoma patients were divided into two groups: conventional group (68 eyes) underwent routine trabeculectomy; adjusted suture group (70 eyes) underwent adjustable suture trabeculectomy. The postoperative shallow anterior chamber formation and intraocular pressure were observed. Results There were 25 eyes (36.76%) in the control group and 6 eyes (8.57%) in the control group (P <0.01). Intraocular pressure (IOP): Sixty-two eyes (88.24%) underwent intraocular pressure control <21mmHg in conventional group and 62 eyes (88.57%) under intraocular pressure control <21mmHg in suture group, P> 0.05. Conclusion Adjusting suture trabeculectomy can reduce the incidence of postoperative shallow anterior chamber, but also effectively reduce intraocular pressure and improve the success rate of glaucoma surgery.
