6点位小梁切除术的临床研究

Clinical study to inferior trabeculectomy

目的:探讨6点位小梁切除术的手术适应证和疗效。方法:对在上方角巩膜缘做过内眼手术的28例(31眼)行6点位小梁切除术,随访观察手术疗效及并发症。结果:术后随访半年,眼压在1.33～2.8kPa之间者26眼(83.9%),其中完全不用药物者11眼(35.5%),仅用0.5%噻吗心安控制者15眼(48.4%);随访2.5年者26眼,眼压正常者21眼(80.7%),其中完全不用药物者10眼(38.4%),仅用0.5%噻吗心安眼水控制者11眼(42.3%)。并发症包括脉络膜脱离、浅前房、滤过口纤维增生等,经及时处理多能恢复正常。讨论:对曾在上方角巩膜缘行内眼手术,又需要行抗青光眼手术的患者,6点位小梁切除术较其他术式具有更高的安全性,是一种有效的治疗方法。但因操作不便,需要合理掌握适应证。

rurpose:lo study the indications and complications of the inferior trabeculectomy.Methods:A half year fol- low- up study on 31 postoperative eyes was made,26eyes were followed up for 2.5years,and the effect and the complications of the surgery were observed.Results:After a half year,the intraocular pressure of 26 eyes was in this range by using Timolol(15 eyes,48.4 %)or not(11 eyes,-35.5%).after 2.5 years,the intraocular pressure of 21 eyes(80.7%)in 26 follow - up eyes were controlled,10 eyes(38.4%)with no medicine and 11 eyes(42.3%)using Timolol.The postoperative complications include choroid detachment,shallow anterior chamber and fibril proliferation of filtering blebs.Most of them can be resumed by treatment in time.Conclusions:To the patients who need the secondary anti - glaucoma surgery,the inferior trabeculectomy is an effective and safe method.However,we should use this method carefully for it is difficult to perform the operation.
