原发性闭角型青光眼持续高眼压状态下的手术治疗

目的探讨原发性闭角型青光眼持续高眼压下施行小梁切除术的手术要点及治疗效果。方法:对21例22眼急性闭角型青光眼持续高眼压状态患者,术前、术中用多种方法使眼压逐渐下降后,进行小梁切除术。结果:术后6～12mo,22眼中有17眼术后不用抗青光眼药物,眼压能控制在21mmHg(1mmHg=0.133kPa)以下,4眼加用降眼压药物眼压控制正常;19眼视力有所提高,无严重并发症。结论:对于应用药物治疗不能有效控制眼压的青光眼患者,应当机立断进行手术治疗。只要完善术前准备,术中精心操作,术后精心护理,高眼压下小梁切除术是必要、安全、有效的。

Surgical treatmeng of primary angle-dosure glaucoma with persistent high intraocular pressure

Objective To observe the points and effects of the trabeculeetomy in primary angle-closure glaucoma（PACG） with persistent high intraocular pressure（IOP）. Methods The trabeculectomy was performed on 22 eyes （21 cases） after the lOP and had been reduced with many kinds of methods in procedures ofpre-operation and intra-operation. Results The IOP was less than 21mmHg in 17 eyes without any antiglaucoma-drug and in 4 eyes with lower lOP drugs after 6-12 months of the operation. The visions of 19 eyes were raised. There were no serious complications. Conclusion Once the lOP cannot be controlled, surgical treatment should be undertaken at once. It is necessary and safe and effective to perform the trabeculectomy on PACG with persistent high lOP under careful preparing and operating and post-operation nursing.
