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 investigate the morphological changes of shallow anterior chamber caused by ciliary body detachment after glaucoma surgery and its clinical significance. Methods: The ophthalmologic ultrasound B ultrasound and ultrasound biomicroscopy (UBM) were used to observe the morphology of eye and healthy eye after ciliary body detachment in glaucoma surgery. The related data were statistically analyzed. Results: UBM can not diagnose B ultrasound diagnosis of ciliary body detachment and choroidal detachment, can specifically check the diagnosis. Its characteristic features: there is no echo between the sclera and the ciliary body, ciliary body position forward, anterior, ciliary body flat part of the axis of the eye to move part of the ciliary body can be seen flat was layered separation The reason for the shallow anterior chamber is that the ciliary processes twist forward, causing the iris to bulge and displacing the lens forward. All ciliary body detachment from the eye were 360 degrees off the whole week, rather than a quadrant of the detachment, without choroidal detachment due to simple ciliary detachment due to glaucoma postoperative shallow anterior chamber, generally not completely disappeared anterior chamber Conservative treatment can be effective. Conclusion: UBM can be used to diagnose shallow anterior chamber glaucoma after debridement of ciliary body, so as to provide a reliable basis for clinical treatment.
