目的:探讨玻璃体切割术后持续性继发性青光眼的可能原因及其治疗方法。方法:回顾性分析2004-01/2010-01在我院行玻璃体切割术后出现持续性继发性青光眼的患者20例20眼,对患者进行眼压监测,行房角镜,超声生物显微镜检查,确定继发性青光眼的原因,并根据不同的原因相应地给予药物或手术治疗,观察治疗后眼压、视力等变化。结果:玻璃体切割术后持续性继发性青光眼患者20例20眼,高眼压发生的时间为玻璃体切割术后2wk～3mo,眼压均在30～50mmHg之间,房角镜及超声生物显微镜示房角关闭15例15眼,房角开放5例5眼；继发性青光眼发生的原因可能为:局部应用皮质类固醇时间过长引起的青光眼3例3眼,新生血管性青光眼4例4眼,术后炎性物质堵塞房角8例8眼,术后前房积血,玻璃体积血堵塞房角3例3眼,另2例原因不明。结论:玻璃体切割术后继发性持续性青光眼引起的原因包括局部应用皮质类固醇时间过长,患者新生血管形成,术后炎性物质或者出血堵塞房角,其治疗方法应根据不同的原因相应地治疗:停用皮质类固醇；810激光睫状体光凝术；小梁切除术或引流阀植入术等。

AIM:To evaluate the cause and therapy for secondary glaucoma following vitrectomy.METHODS:Twenty patients with secondary glaucoma following vitrectomy were analyzed retrospectively. In order to determine the cause of secondary glaucoma, intraocular pressure(IOP), ultrasound biomicroscopy(UBM) and chamber-angle microscopy were taken, according to the different cause of secondary glaucoma, drug or surgery was selected.RESULTS:The IOP elevation occurred mostly within two weeks to three months. The IOP was 30-50mmHg. The angle closed in 15 patients with the examination by chamber angle microscopy and UBM the others remained open. The main cause of secondary glaucoma included long-time applying topical steroid, iris neovascularization and anterior inflammation and hemorrhage.CONCLUSION:Secondary glaucoma following vitrectomy is a complicated complication. The different therapy may select according to the different cause.
