【摘要】：目的研究超声生物显微镜技术(UBM)对于原发性闭角型青光眼的诊断价值。方法选择120例原发性闭角型青光眼患者,根据急性与慢性闭角型青光眼分别编入急性组与慢性组。采用UBM检查并对比2组房角及解剖结构。结果 UBM定量检测结果显示,2组角膜厚度、晶状体厚度及眼轴长度比较差异无统计学意义(P均0.05);急性组前房深度、前房角、房角开放距离500、虹膜-晶状体接触距离,巩膜-虹膜夹角、小梁-睫状体距离及巩膜-睫状突夹角均明显低于慢性组(P均0.05);UBM半定量分析显示,急性组周边虹膜主要为偏薄型及中间型,而慢性组主要为中间型及肥厚型;在急性组虹膜膨隆型占98%,而慢性组中虹膜平坦型占80%;急性组睫状体位置主要为靠前型及居中型,而慢性组主要为居中型及靠后型。结论急性闭角型青光眼具有虹膜膨隆、睫状体位置靠前的特点,其房角关闭机制主要由瞳孔阻滞引起,慢性闭角型青光眼则由多种机制共同作用引起。采用UBM可有助于原发性闭角型青光眼急慢性区分及早期诊断。
[Abstract]:Objective to study the diagnostic value of ultrasound biomicroscopy (UBM) for primary angle closure glaucoma. Methods 120 cases of primary angle closure glaucoma were selected, and the acute and chronic angle closure glaucoma were included in the acute and chronic glaucoma group. The angle and anatomical structure of 2 groups were examined and compared by UBM. The quantitative results of UBM assay showed that the 2 groups had no statistical significance of corneal thickness, lens thickness and axial length difference (P 0.05); the acute group, anterior chamber depth, anterior chamber angle, angle opening distance 500, iris lens contact distance, sclera angle, trabecular iris ciliary body distance and sclera ciliary process angle was significantly lower than that in the chronic group (P < 0.05); semi quantitative UBM analysis showed that the group of acute peripheral iris mainly for partial thin and intermediate type, and chronic group is mainly intermediate and hypertrophic; in the acute Group Iris bombe accounted for 98%, while in the chronic Group Iris flat type accounted for 80%; the acute group of ciliary body position is mainly on the type and middle type, and chronic group is mainly centered on the type and type. Conclusion acute angle closure glaucoma is characterized by iris distention and anterior ciliary body location. The mechanism of angle closure is mainly caused by pupillary block. Chronic angle closure glaucoma is caused by multiple mechanisms. The use of UBM can be helpful to the acute and chronic diagnosis of primary angle closure glaucoma.

【正文快照】： 青光眼以特征性视神经萎缩与视野缺损为临床特征,是眼科常见眼病,其致盲率可高达15%~20%,属于三大致盲眼病之一。在所有青光眼类型中以闭角型青光眼最为常见,可占全部青光眼类型中60%~80%。原发性闭角型青光眼主要由眼部解剖结构异常导致房角结构狭窄,前房角关闭,房水排出受阻
