目的 评价超声生物显微镜(UBM)对睫状体脱离检测的可行性。方法 检测50 例患者(视网膜脱离25 例,视网膜脱离术后20 例,顿挫伤5 例)睫状体脱离的情况。临床检查与UBM 及B超结果进行x2 检验。眼内压与睫状体脱离宽度行回归分析。结果 50 例中UBM 发现睫状体脱离35 例,其中B超阳性发现8 例、临床诊断6 例。统计学检验有非常显著差异( P< 0.001)。UBM 发现睫状体脱离可分为三种:裂隙状、条带状和楔状,相应睫状体脱离程度递增,且B超与临床检出率亦逐渐提高。眼内压与睫状体脱离宽度呈负相关(r= - 0.43, P < 0.05)。一例人工晶体植入术后继发视网膜脱离眼中发现前部玻璃体增殖,牵引睫状体脱离,另一例外伤眼发现下方睫状体截离。结论 超声生物显微镜是一种分辨率较高的检测手段,对睫状体脱离的程度、范围及病因研究均有重要意义
Objective To evaluate the feasibility of using UBM to detect ciliary body detachment. Methods 50 patients (retinal detachment in 25 cases, retinal detachment in 20 cases, 5 cases of contusion) ciliary body detachment. Clinical examination and UBM and B-results of x2 test. Line regression analysis of intraocular pressure and ciliary body detachment width. Results In 50 cases, 35 cases of ciliary body detachment were found by UBM, including 8 cases of B-positive and 6 cases of clinical diagnosis. Statistical tests have very significant differences (P <0.001). UBM found that ciliary body detachment can be divided into three types: fissure-like, strip-shaped and wedge-shaped, the corresponding degree of ciliary body detachment increased, and B-and clinical detection rate also gradually increased. Intraocular pressure and ciliary body detachment width was negatively correlated (r = - 0.43, P <0.05). One case of secondary retinal detachment after intraocular lens implantation found anterior vitreous proliferation, traction ciliary body detachment, the other case of traumatic eye found below the ciliary body cut off. Conclusion Ultrasound biomicroscopy is a high resolution detection method, which is of great significance to the extent, scope and etiology of ciliary body detachment
