摘要
目的 通过超声生物显微镜（UBM）观察巩膜瓣下深层纵形小梁切除术后的房角情况并探讨其术式的降眼压机制。方法 采用巩膜瓣下深层纵形小梁切除术对患各种不同类型青光眼的85名患者进行手术治疗，在术后检查以及其后的随访期间使用加拿大OTI Scan1000型超声生物显微镜观察其术眼并监测眼压，随访时间3-30个月，平均（7.9±6.2）个月。结果 UBM观察术后均形成明显弥散性滤过泡，平均眼压（14.22±3.62）mmHg。随访过程中，54眼有功能性滤泡;16眼术后2-3个月功能性滤过泡消失。结论 UBM检查能直观地了解巩膜瓣下深层纵形小梁切除术后的眼前段状态，并能对该手术的降眼压效果及术后远期疗效作出评估。
Objective To observe anterior chamber by using ultrasound biomieroseopy （UBM） after modified trabeeuleetomy in deep of scleral flap and investigate the mechanism of decreasing intraocular pressure in this type of operation. Methods Eighty-five patients with varied glaucoma were treated with excision of deep layer sclera and trabecular by vertical limbus, then observed by using Canada OTI Scan 1000 UBM and examined the intraocular pressure postoperatively from 3 to 30 months （mean period [7.9±6.23 months）, Results The observation of UBM indicated that the filtering blebs were showed distinctly. The average postoperative intraocular pressure were （14.22±3.62） mmHg. During the follow-up the functional filtering blebs of 54 eyes were present while those of 16 eyes were disappeared after 2-3 months postoperatively. Conclusion We could conclude the anterior segment configuration of the glaucoma treated with modified trabeculectomy by UBM more safely and directly than traditional examination, and evaluate the effect of the decreasing intraocular pressure of the operation and further treatment postoperatively.
