To evaluate the ability of high-frequency ultrasound biomicroscopy to diagnose traumatic cyclodialyses not evident on clinical examination.
Six eyes to six patients with posttraumatic hypotony and/or shallow anterior chamber and suspected cyclodialysis clefts were examined with slit-lamp biomicroscopy, gonioscopy, B-scan ultrasonography, and ultrasound biomicroscopy. Ultrasound biomicroscopy provided high resolution of cross-sectional images of the anterior chamber angle, posterior chamber, and anterior uveal tissue.
Ultrasound biomicroscopy confirmed the disinsertion of the ciliary body from the scleral spur and associated ciliary body detachment in all eyes. Gonioscopy failed to demonstrate a cyclodialysis cleft in five eyes because of hyphema (two eyes) and abnormal iris architecture (related to trauma) precluding visualization of the angle recess (three eyes). Using information from ultrasound biomicroscopy imagining, one patient underwent a ciliary body reattachment procedure and repair of the cyclodialysis cleft.
Ultrasound biomicroscopy is a noninvasive method that can accurately diagnose the presence of traumatic cyclodialyses and can aid in surgical management. It is particularly useful in the presence of hazy media, hypotony, and/or abnormal anterior segment anatomy.
评估高频超声生物显微镜检查诊断临床检查未发现的外伤性睫状体脱离的能力。
对6例患有外伤性低眼压和/或浅前房且疑似睫状体脱离裂孔的患者的6只眼进行裂隙灯生物显微镜检查、前房角镜检查、B超超声检查和超声生物显微镜检查。超声生物显微镜检查可提供前房角、后房和前部葡萄膜组织的高分辨率横断面图像。
超声生物显微镜检查证实所有患眼均存在睫状体从巩膜突分离及相关的睫状体脱离。由于前房积血（2只眼）和虹膜结构异常（与外伤有关）妨碍了前房角隐窝的观察（3只眼），前房角镜检查未能在5只眼中发现睫状体脱离裂孔。根据超声生物显微镜检查成像提供的信息，1例患者接受了睫状体复位手术及睫状体脱离裂孔修复术。
超声生物显微镜检查是一种无创方法，可准确诊断外伤性睫状体脱离的存在，并有助于手术治疗。在存在混浊介质、低眼压和/或前部节段解剖结构异常的情况下尤其有用。
