青光眼滤过手术后高眼压的临床分析

目的：探讨青光眼患者行小梁切术后发生高眼压(>21mmHg)的常见原因及处理方法。
　　方法：回顾性研究我院2010-07/2014-09青光眼患者行小梁切除术后出现高眼压的病例24眼，分析其常见原因、处理方法。
　　结果：导致术后早期高眼压的因素有：发生滤过泡瘢痕11眼(46%)、滤过内口阻塞4眼(17%)、恶性青光眼3眼(12%)、虹膜切除不合理2眼(8%)、前房积血2眼(8%)、包裹性囊状滤过泡2眼(8%)。经对症治疗后，患者眼压均控制在21 mmHg以下。
　　结论：青光眼行小梁切除术后高眼压是由多因素造成的，术前、术中尽量避免，术后及早发现给予对症处理是手术成功的关键。

Clinical analysis of high intraocular pressure after trabeculectomy

AIM: To analyze the common causes and treatments methods of high intraocular pressure(>21mmHg)after trabeculectomy.

METHODS: Twenty-four eyes of glaucoma patients with high intraocular pressure after trabeculectomy in our hospital from July 2010 to September 2014 were retrospectively studied. The common cause and processing methods were analyzed.

RESULTS: The causes which lead to early postoperative high intraocular pressure included high filtering bleb scar in 11 eyes(46%), filtration obstruction in 4 eyes(17%), malignant glaucoma 3 eyes(12%), iris resection of malignant glaucoma unreasonable 2 eyes(8%), hyphema 2 eyes(8%), wrap cystic filtering bleb 2 eyes(8%), etc. After proper treatments, intraocular pressures of all patients were bellowed 21mmHg.

CONCLUSION: High intraocular pressure with surgery for glaucoma is caused by multiple factors, preoperative and intraoperative avoid as far as possible, postoperative early detection for symptomatic treatment is the key to successful operation.
