改良式小梁切除术在持续高眼压的青光眼手术中的应用

目的 观察持续高眼压状态下青光眼手术中改良式小梁切除术的临床应用效果。方法将改良式小梁切除术应用于持续高眼压状态下的急性闭角型青光眼的治疗，共52例（65眼）。采用表面麻醉和2％利多卡因棉片浸润麻醉。用隧道刀做板层巩膜瓣；在小梁切除部位做前房穿刺，慢放房水；术中散瞳，术毕睫状肌麻痹剂应用。结果术中术后均未出现脉络膜出血、脉络膜脱离、玻璃体脱出或睫状环阻塞性青光眼等严重并发症。随访3—6个月，眼压控制正常，视力无下降。结论改良小梁切除术应用于持续高眼压状态下青光眼安全有效，及时手术能维持部分视功能。

Applied study of modified trabeculectomy in glaucoma surgery with elevated intraocular pressure

Objective To observe the clinical effect of modified trabeeulcclomy in glaucoma surgery with elevated intraocular pressure. Methods To analyzed 52 patients （65 eyes） of acute angle-closure glaucoma with elvaled intraocular pressure. They were treated by modified trabeeuleetomy. The modified measures include that topical anesthesia and local anesthesia with 2% lidocaine cotton-piece ,to make scleral flap with sclerotome, to release aqucous outflw slowly after paraecntesis of anterior chamber,and using mydriatie and cyeloplegic in and after surgery. Results There were no complications of ehoroid hemorrhage, choroid detachment or vitreous detachment. The followed up was 3 - 6 months. The intraocular pressure was controled in normal range. The visual was no loss. Conclusion The modified trabeculectomy appled in elevated intraocular pressure is effective and safe. It can contect parted visual function.
