| 【摘要】 目的 分析外伤性睫状体断离患者的致伤原因以及临床特征的分布，为全面和准确掌握外伤性睫状体断离的诊断提供依据。方法：回顾分析了2001年4月—2007年1月在本中心眼科就诊的睫状体断离病例241人242眼，男性204眼，女性38眼，年龄范围1.5—60岁，全部受伤眼被分成以下4组：（1） 低眼压并浅前房；（2） 低眼压但正常前房；（3） 正常眼压但浅前房；（4） 正常眼压并正常前房。分析全部病例手术前的致伤因素、发病时间、眼内压（IOP）、前房深度（AC）的分布特点。结果：主要的外伤原因是拳击伤、鞭炮和车祸伤，致伤率分别占30.2%、10.3%、9.5%，其次为木块（棍）伤、脚踢伤、石块伤、跌落伤、爆炸伤等。各组的体征分布特点为：（1）低眼压并浅前房，占57.0%；（2）低眼压但正常前房，占19.8%；（3）正常眼压但浅前房，占16.9%；（4）正常眼压并正常前房，占6.2%。结论：外伤性睫状体断离病人主要的外伤原因依次是拳击伤、鞭炮和车祸伤。对于诊断而言，低眼压并浅前房是主要的体征，但并不是必要的体征。超声生物显微镜（UBM）对于诊断有决定性意义。
【Abstract】 Objective To analyze the distribution of cause of cyclodialysis and the features of the sign. Patients and methods: 241 cases (242 eyes) of cyclodialysis attended Tongren Hospital from April 2001 to January 2007 were retrospectively reviewed. All cases were divided into four groups based on the features of depth of anterior chamber (AC) and the value of intraocular pressure (IOP). The etiological factors and features of the AC and IOP were analyzed. Results: Varied etiologies of traumatic cyclodialysis are available, major causes include fisting attack, explosive firecracker and traffic accident, the incidence is respectively 30.2%, 10.3%, 9.5%, following causes are clubbing attack, kicking attack, stone attack, falling injury, explosive accident, and the some miscellaneous causes. Commensurate with the percentage of each group, there are varied values: (1) shallow AC and low IOP, 57.0%; (2) normal AC but shallow IOP, 19.8%l; (3) shallow AC but normal IOP, 16.9%; (4) normal AC and normal IOP, 6.2%. Conclusions: The three major etiologies of traumatic cyclodialysis include fisting attack, explosive firecracker and traffic accident. Shallow AC combined with low IOP is dominant clinical sign, however, neither of the two could be regarded as necessary one for diagnosis. Ultrasonic biomicroscopic (UBM) images are decisive to diagnosis. |
