超声生物显微镜在睫状体脱离复位术中的应用价值

Application of ultrasound microscope for the reattachment surgery of detachment of ciliary body

目的评价超声生物显微镜（ｕｌｔｒａｓｏｕｎｄｂｉｏｍｉｃｒｏｓｃｏｐｅ，ＵＢＭ）在挫伤性睫状体脱离复位手术中的应用价值。方法对３３例经ＵＢＭ检查证实为睫状体脱离的患者进行手术分析评价，并回顾总结单纯应用前房角镜检查施行睫状体复位８３例的手术效果。结果经ＵＢＭ检查３３例中，一次手术眼压恢复正常者３１例，占９４％；二次手术成功率１００％。前房角镜检查８３例，一次手术成功６８例，占８２％，二次手术成功率９４％；三次手术成功率９６％。结论ＵＢＭ检查对于前房角镜下不能看到的小而窄的睫状体脱离可提供精确的数据，对诊断、指导手术缝合范围及术后效果追踪观察等有重要的临床应用价值。减少了手术的次数及盲目性。

Objective To evaluate the advantages of ultrasound biomicroscope (UBM) used for the reattachment surgery of traumatic ciliary body detachment. Mehtods 33 cases diagnosed by UBM as ciliary body detachment were studied. The surgical results of these cases were analyzed and compared with that of 83 cases which were simply diagnosed by a gonioscope. Results 31 of the 33 cases regained the normal intraocular pressure (IOP) after once of operation (94%), and all cases achieved successful results after twice of operation (100%). Of the 83 cases examined only by gonioscopy, the rates of reaching normal IOP after the 1 st , 2 nd and 3 rd operations were 82%, 94% and 96% respectively. Conclusions These results suggest that the UBM be useful for the tiny and narrow detachment of ciliary body which can not be seen by a gonioscope. UBM has important clinical value in diagnosis, guide to the range of suture and follow up observation. With the use of UBM, the frequency of operation necessary for surgical success and blindness in action in the operation will be reduced, and the successful rate of once of operation will be increased significantly.
