摘　　要：目的总结眼挫伤后低眼压的超声生物显微镜(UBM)诊断结果,分析眼挫伤后低眼压产生的原因,并评价该项新技术的诊断价值。方法22例(22眼)眼挫伤后低眼压接受了UBM检查。对每一病例常规探查9个切面,观察前房、瞳孔、前房角、虹膜及睫状体等的改变并采集图像,可疑部位重点观察房角及睫状体情况,并记录病变范围。结果22例低眼压中位病程3月,平均眼压6.42mmHg。22眼均存在全周睫状体脱离,19眼存在睫状体分离房角漏(86.36%)。房角漏范围从0.5到4个钟点,并呈现4种不同的形态。22眼中7眼根据UBM及临床检查结果实行了睫状体缝合手术。结论经脉络膜上腔途径的房水引流增加是眼挫伤后低眼压的主要原因。UBM对于眼挫伤后低眼压尤其是伴有睫状体分离房角漏的病例的诊断和治疗均具有较高的参考价值。Objective To summarise the results of ultrasound biomicroscopy （UBM） in the diagnosis of posttraumatie ocular hypotony, analyes the main cause of ocular hypotony, and evaluate the diagnustic ability of UBM.Methods 22 eyes of 22 patients with posttraumatic hypotony received UBM examination.9 cross-sectional images was captured for every patient with special attention to ciliary body and angle, Results The mean IOP of 22 patients was 6.42 mmHg. Medium durathm of hypotony was 3 months. Ciliary body detachment was present in 22 eyes,Cyclodialysis cleft was present in 86.36% of the eyes, The extent of cyclodialysis cleft varied from 0.5 to 4 hours, The shapes of cyclodialysis cleft can be divided into tour types, We performed ciliary body suturing to 7 patients according to the results of UBM examination. Conclusions The increase of aqueous outflow via suprachoroidal space is the main cause of posttraumatic ocular hypotony, UBM can be of great value in the diagnosis and management of patients with posttraumatic ocular hypotony especially eyclodialysis cleft.
