小梁切除术后前房迟缓形成是该手术的严重并发症。如术后2～3天前房不恢复,就有可能发生下列并发症:虹膜后粘连、虹膜周边前粘连、并发性白内障、角膜水肿和滤过泡消失。作者报告处理前房迟缓形成的方法如下: 手术中采取下列措施预防前房迟缓形成:缝合巩膜瓣之后,作角膜穿刺注入生理盐水以恢复前房。如果前房不恢复,就在巩膜瓣上多加缝线。连续缝合球结膜,再在角膜穿刺处注入生理盐水。检查球结膜缝合处有无渗漏,必要时加间断缝线。术终滴散瞳剂,放松睫状体,拉紧晶体小带,有助于保持前房深度。
The delayed formation of anterior chamber after trabeculectomy is a serious complication of the operation. Such as postoperative 2 to 3 days before the room does not recover, there may be the following complications: posterior iris adhesions, iris adhesions around the front, complicated cataract, corneal edema and filtration disappear bleb. The authors report that the treatment of delayed formation of the anterior chamber is as follows: During the operation, the following measures are taken to prevent the formation of anterior chamber retardation: After the scleral flap is sutured, saline is injected into the cornea to restore the anterior chamber. If the anterior chamber is not restored, more suture in the scleral flap. Continuous suture conjunctiva, and then into the corneal puncture at normal saline. Check for conjunctival suture leakage, if necessary, add intermittent suture. Intraoperative end-tidying pupil agent to relax the ciliary body, taut crystal small belt, helps to maintain the depth of the anterior chamber.
