虹膜周切术后高眼压的原因分析

目的探讨手术周边虹膜切除或激光虹膜切除术后高眼压的原因。方法经鼻上方透明角膜切口行虹膜周切术。局部氪激光鼻上11：00周边虹膜成型＋Nd：YAG激光虹膜周切术。术后行眼压、房角、前房深度及暗室试验等检查,发现高眼压病例行虹膜周切区、房角镜检查了解其原因。结果 22例29眼中,虹膜周切口色素上皮层未切透3例3眼,术前房角检查诊断欠准确6例6眼,高褶虹膜2例4眼,窄角性开角型青光眼2例4眼,混合性青光眼1例2眼,多种机制共同参与8例10眼。讨论：青光眼患者除准确房角检查和选择准确术式外,术后仍行眼压、房角、前房深度及暗室激发试验检查,以便及时发现眼压增高做出处理。

Discussion on the peripheral iridectomy causes high intraocular pressure after surgery

Objective The reason of high intraocular pressure after excision or Laser Iridectomy on operation of peripheral iris.Methods Nasal above clear corneal incision line iridectomy,Nd：YAG laser iridectomy with local iridoplasty by krypton laser in nasal 11：00。Postoperative intraocular pressure,angle,depth of anterior chamber and anechoic chamber tests,Found in cases with high IOP peripheral iridectomy zones、gonioscopy and understand its causes.Results In all cases,there were 3 eyes with remained pigained in peripheral hole,6 eyes and anterior chamber angle examination in diagnosis of less accurate,Plateau iris in 4 eyes,Narrow-angle and open-angle glaucoma 4 eyes,mixed glaucoma 2 eyes,In a variety of mechanisms 10eyes.Conclusion Except for choosing the proper surgical and accurate chamber angle examination。It is very important to check the IOP depth of anterior chamber,gonioscopy and irritation tests to get the early diagnosis and management.
