目的：应用国产超声生物显微镜(UBM)观察原发性闭角型青光眼行激光周边虹膜切除术的疗效。
方法：原发性闭角型青光眼(包括急性、慢性)患者31例43眼，术前术后分别用UBM测量术眼中央前房深度(ACD)以及12：00，3：00，6：00，9：00四个方向的房角开放距离(AOD)及房角开放度数(AA)，并观察眼压。
结果：术前术后眼压、中央前房深度比较无统计学差异，术前术后四个方向的AOD及AA均有增加，有统计学差异。
结论：UBM能观察活体的手术前后的房角变化、激光通畅程度，为原发性闭角型青光眼的诊治提供了更有效的检查方法和疗效观察。

AIM: To evaluate the therapeutic effects of Nd:YAG laser in primary angle-closure glaucoma(PACG)by domestic ultrasound biomicroscopy(UBM).
METHODS: PACG(including acute, chronic)patients, a total of 31 cases 43 eyes were included in this study. UBM measurement of intraoperative central anterior chamber distance(ACD), and the angle opening distance(AOD)in 12:00, 3:00, 6:00, and 9:00 four directions, angle opening in degrees(AA), and intraocular pressure(IOP)was performed before and after surgery, respectively.
RESULTS: The postoperative IOP and central ACD had no significant difference compared with that of preoperative. AOD and AA increased significantly preoperatively and postoperatively in four directions.
CONCLUSION: Angle changes and laser patency can be observed in vivo before and after surgery by UBM, which is a more effective method for diagnosis and treatment of PACG.
