Suture lysis is commonly performed after trabeculectomy to improve bleb function. It is often thought to be an innocuous procedure. This is the first large study to determine the safety of the procedure and compare results with a control group.
Two hundred successive trabeculectomies performed between January 1992 and October 1993 were analysed.
Ninety nine eyes underwent trabeculectomy and suture lysis; 101 eyes underwent trabeculectomy and did not require postoperative suture lysis. The following complications were noted with suture lysis: flat chambers (13.1%), external aqueous leaks (9%), malignant glaucoma (2%), iris incarceration (2%), and large blebs (2%). All resolved with appropriate management. There was no significant difference in the final postoperative mean pressures between the lysis and the non-lysis groups.
Suture lysis is not an innocuous procedure. However if managed appropriately, complications do not affect the intraocular pressure outcome.
小梁切除术后常进行缝线松解以改善滤过泡功能。人们通常认为这是一个无害的手术。这是第一项确定该手术安全性并与对照组比较结果的大型研究。
分析了1992年1月至1993年10月期间连续进行的200例小梁切除术。
99只眼接受了小梁切除术和缝线松解；101只眼接受了小梁切除术且术后不需要缝线松解。缝线松解出现了以下并发症：前房变平（13.1%）、房水外漏（9%）、恶性青光眼（2%）、虹膜嵌顿（2%）和大滤过泡（2%）。所有这些并发症经适当处理后均得到解决。松解组和未松解组术后最终平均眼压无显著差异。
缝线松解并非无害手术。然而，如果处理得当，并发症不会影响眼压结果。
