目的探讨眼部睫状体脱离的形态学改变及其临床意义。方法应用超声生物显微镜（ｕｌｔｒａｓｏｕｎｄｂｉｏｍｉｃｒｏｓｃｏｐｙ,ＵＢＭ）对１７３例睫状体脱离的患眼与健眼的形态进行观察,并对其测量的相关参数进行统计学分析。结果所有睫状体脱离眼均为３６０°全周脱离,而非某一象限的脱离。ＵＢＭ探查睫状体脱离的特征性表现：巩膜与睫状体间存在无回声区,睫状突位置前移、前旋,睫状体平坦部向玻璃体中轴部位移动,部分患者可见睫状体平坦部呈层间分离。部分患者可显示虹膜、睫状体与巩膜附着点完全脱离,形成睫状体离断,离断的范围可为眼球的某一象限而非眼球全周,致使前房与睫状体上腔之间形成完全沟通的瘘口。脱离眼的前房深度（２１１５±５８９）μｍ较未脱离眼的前房深度（２７３６±４４１）μｍ浅（ｔ＝４．４９,Ｐ＜０．００１）,前房变浅的原因是睫状突前移、前旋导致虹膜根部膨隆。结论应用ＵＢＭ检查可以明确地诊断睫状体脱离,且不受屈光间质条件的限制,将为临床治疗提供可靠的依据。     

Ultrasound Biomiscroscopy in the diagnosis and management of cyclodialysis clefts

PURPOSE: To report the role of Ultrasound Biomicroscopy (UBM) as a tool in the diagnosis and management of cyclodialysis clefts. METHODS: Six eyes of 6 patients with hypotony and suspected or diagnosed cyclodialysis clefts underwent UBM evaluation. Post-treatment UBM was performed in four eyes to assess the effect of the treatment. RESULTS: Cyclodialysis clefts were accurately diagnosed and delineated in 6 eyes by UBM. Complete closure was documented after treatment in 3 eyes, and a residual cleft in one eye. These findings were compared to gonioscopic findings. CONCLUSIONS: UBM is a safe, accurate and noninvasive diagnostic tool in the diagnosis of cyclodialysis clefts and is of particular use when other conventional methods of diagnosis are inconclusive.

Evaluation and comparison of indentation ultrasound biomicroscopy gonioscopy in relative pupillary block, peripheral anterior synechia, and plateau iris configuration

PURPOSE: To evaluate and compare the findings and changes of the anterior chamber angle configuration with indentation ultrasound biomicroscopy (UBM) gonioscopy in relative pupillary block (RPB), peripheral anterior synechia (PAS), and plateau iris configuration (PIC). METHODS: This study included 73 eyes of 52 patients with RPB (n = 26), PAS (n = 21), or PIC (n = 26). First, a conventional UBM scan was performed using a normal size standard eye cup before indentation. Then, for indentation UBM gonioscopy, scans were performed using a new eye cup that we designed. For evaluation of the angle, angle opening distance 500 and angle recess area were recorded and evaluated with regard to the effect of expansion on the anterior chamber angle. RESULTS: Indentation UBM gonioscopy showed the characteristic images in each of the eyes. The angle of all examined eyes was significantly widened with indentation (P < 0.01). The angle changes in eyes with RPB were significantly greater than in eyes with PAS or PIC (P < 0.01). CONCLUSION: Indentation UBM gonioscopy is a very useful method for observing the angle and diagnosis of RPB, PAS, and PIC.     

超声生物显微镜对外伤性睫状体分离缝合复位术的临床应用价值

目的探讨超声生物显微镜对外伤性睫状体分离的诊断以及缝合复位术治疗的临床意义。方法回顾性分析51例（51眼）外伤性睫状休分离缝合复位术的临床资料,并对有关数据进行统计学分析。结果经超声生物显微镜检查,病例均被确诊为外伤性睫状体分离。缝合复位术后,视力明显提高（P=0．000）。睫状体分离范围与术后眼压恢复至正常范围所需时间以及术后最佳矫正视力提高水平均存在相关性（P=0．002,P=0．011）。睫状体分离病程持续时间与术后最佳矫正视力提高水平存在相关性（P=0．000）,而与术后眼压恢复至正常范围所需时间无相关性（P=0．161）。结论超声生物显微镜检查对外伤性睫状体分离的诊断、手术治疗、术后随访以及预后视力评估具有重要的临床应用价值。     

Cyclodialysis cleft diagnosed by conventional ultrasonography

This case report describes the diagnosis and management of a traumatic cyclodialysis cleft, in the absence of newer investigating modalities like ultrasonic biomicroscopy (UBM). This entity is frequently difficult to recognize clinically owing to the extreme hypotony and media haze that these patients usually present with, which makes gonioscopy particularly taxing. Adding to the diagnostic dilemma is the difficulty in delineating the lesion ultrasonically due to the extreme anterior location of the cleft. In these situations, high frequency ultrasound has been found to be extremely helpful, but the availability of such sophistication is difficult. Presented here is demonstration of the cleft with a microconvex ultrasound probe of 9 MHz frequency. The patient was successfully managed conservatively. This modality could prove to be a valuable adjunct to the diagnosis of such cases even in the situations of nonavailability of high frequency ultrasonography.     

Evaluation of the anterior chamber angle in Asian Indian eyes by ultrasound biomicroscopy and gonioscopy

PURPOSE: To compare the ultrasound biomicroscopic measurement of the anterior chamber angle in Asian Indian eyes, with the angle width estimated by gonioscopy. MATERIALS AND METHODS: Participants: Patients with open and closed angles attending a glaucoma clinic were recruited for the study. OBSERVATION PROCEDURES: Temporal quadrants of the angles of patients were categorized by gonioscopy as Grade 0 to Grade 4, using Shaffer's classification. These angles were quantified by ultrasound biomicroscopy (UBM) using the following biometric characteristics: Angle opening distance at 250 micro (AOD 250) and 500 micro (AOD 500) from the scleral spur and trabecular meshwork-ciliary process distance (TCPD). The angles were further segregated as "narrow angles" (Schaffer's Grade 2 or less) and "open angles" (Schaffer's Grade 3 and 4). MAIN OUTCOME MEASURES: The UBM measurements were computed in each case and analyzed in relation to the gonioscopic angle evaluation. RESULTS: One hundred and sixty three eyes of 163 patients were analyzed. One hundred and six eyes had "narrow angles" and 57 eyes had "open angles" on gonioscopy. There was a significant difference among the mean UBM measurements of each angle grade estimated by gonioscopy (P < 0.001). The Pearson correlation coefficient between all UBM parameters and gonioscopy grades was significant at the 0.01 level. The mean AOD 250, AOD 500 and TCPD in narrow angles were 58+/-49 micro, 102+/-84 micro and 653+/-124 respectively, while it was 176+/-47 micro, 291+/-62 micro and 883+/-94 micro in eyes with open angles (P < 0.001) respectively. CONCLUSIONS: The angle width estimated by gonioscopy correlated significantly with the angle dimensions measured by UBM. Gonioscopy, though a subjective test, is a reliable method for estimation of the angle width.
