摘要
目的 :探讨青光眼术后睫状体脱离造成浅前房的形态学改变及其临床意义。方法 :应用眼科传统B超及超声生物显微镜 (ultrasoundbiomicroscopy ,UBM )对青光眼术后睫状体脱离的患眼、健眼形态进行观察并对其测量的相关数据进行统计学分析。结果 :UBM对B超不能诊断的睫状体脱离和脉络膜浅脱离 ,能特异性地进行检查诊断。其特征性表现为 :巩膜与睫状体间存在无回声区 ,睫状体位置前移、前旋 ,睫状体平坦部向眼中轴部位移动 ,部分患者可见睫状体平坦部呈层间分离 ,前房变浅的原因是睫状突向前扭转 ,导致虹膜根部膨隆 ,晶状体向前移位。所有睫状体脱离眼均为 36 0度全周脱离 ,而非某一象限的脱离 ,不伴有脉络膜脱离的单纯睫状体脱离所致的青光眼术后浅前房 ,一般不致前房完全消失 ,保守治疗可奏效。结论 :应用UBM检查可以对睫状体脱离造成的青光眼术后浅前房进行明确诊断 ,为临床治疗提供可靠依据。
Objective:To determine the morphologic changes and their clinical significance of the shallow anterior chamber in cyclodialysis after glaucoma surgery.Method:All eyes of patients with cyclodialysis after glaucoma surgery were examined by conventional B-scan ultrasound and ultrasound biomicroscopy (UBM) for the morphologic changes, and the measurements of relative parameters were analyzed statistically.Results:We can analyze cyclodialysis and choriodal shallow detachment by UBM which can′t do by B-scan ultrasound,and get characteristic diagnosis and analysis. The characteristic manifestations of cyclodialysis found by UBM were as follows:no echoes between sclera and ciliary body,anterior displacement and rotation of ciliary process and displacement of pars plana toward the centre of eyeball.Superciliary effusion could be observed in some cases.The shallow anterior chamber was caused by the anterior displacement and rotation of ciliary processes and the resulting anterior bulging of the iris root,and anterior displacement of ciliary processes.The cyclodialysis in all the cases was 360°. Conclusion:In the shallow anterior chamber after glaucoma surgery with cyclodialysis and without choriodal detachment,anterior chamber can′t completely dissolve usually,and we may provide evidences for treatment.
