UBM 对钝锉伤性低眼压的临床观察及手术效果评价

目的：探讨超声生物显微镜（UBM）对钝锉伤性低眼压的临床观察及手术治疗效果的价值。方法：应用UBM观察55例钝锉伤所致的低眼压患者的治疗情况及手术效果并根据UBM检查决定睫状体离断复位手术的范围。结果：55例应用UBM检查的患者，16例行药物治疗治愈；15例行睫状体脉络膜上腔放液术后，14例治愈，1例未复住；21例行睫状体离断缝合术后，1次手术复位的14例，经UBM检查证实另7例缝合位置靠后或者缝合范围不够，手术失败，再次检查UBM定位重新缝合后，全部治愈。3例放弃手术。结论：UBM检查对于钝锉伤性低眼压可以定性、定量地做出诊断，明确鉴别睫状体脉络膜上腔脱离和睫状体离断，并且可以确定离断的范围及其与相关组织的关系，评价手术的效果及提高手术的成功率。

Application of ultrasound biomicroscopy in clinical observance and operation evaluation of low- tension eyes after contusion

Objective: To evaluate the value in clinical observance and operation of low-tension eyes after contusion using Ultrasound biomicroscopy(UBM).Method: In this study,ultrasound biomicroscopy was used to examine 55patients(55eyes) that were e after contusion.This examination comprised operational range of cyclodialysis reposition and treatment of these cases.Results: In these 55 cases,there were 21 ones that were operated with cyclodialysis reposition(Not only 14 cases recovered well,but also others were operated again then recovered).Another 15 caseswere operated with supraciliaris releasing operation in which only one case went to failure.The rest 16 cases recovered by medicine.Conclusions: Ultrasound biomicroscopy is a qualitative and quantitative technique in the diagnosis of low-tension eyes after contusion.UBM can not only distinguish suprachoroidea dialysis from cyclodialysis accurately,but also offer the degree and extent of cyclodialysis.Also UBM can evaluate the effect of operation so that develop the surgical outcomes.
