【摘要】：目的研究超聲生物顯微鏡技術(shù)(UBM)對(duì)于原發(fā)性閉角型青光眼的診斷價(jià)值。方法選擇120例原發(fā)性閉角型青光眼患者,根據(jù)急性與慢性閉角型青光眼分別編入急性組與慢性組。采用UBM檢查并對(duì)比2組房角及解剖結(jié)構(gòu)。結(jié)果 UBM定量檢測結(jié)果顯示,2組角膜厚度、晶狀體厚度及眼軸長度比較差異無統(tǒng)計(jì)學(xué)意義(P均0.05);急性組前房深度、前房角、房角開放距離500、虹膜-晶狀體接觸距離,鞏膜-虹膜夾角、小梁-睫狀體距離及鞏膜-睫狀突夾角均明顯低于慢性組(P均0.05);UBM半定量分析顯示,急性組周邊虹膜主要為偏薄型及中間型,而慢性組主要為中間型及肥厚型;在急性組虹膜膨隆型占98%,而慢性組中虹膜平坦型占80%;急性組睫狀體位置主要為靠前型及居中型,而慢性組主要為居中型及靠后型。結(jié)論急性閉角型青光眼具有虹膜膨隆、睫狀體位置靠前的特點(diǎn),其房角關(guān)閉機(jī)制主要由瞳孔阻滯引起,慢性閉角型青光眼則由多種機(jī)制共同作用引起。采用UBM可有助于原發(fā)性閉角型青光眼急慢性區(qū)分及早期診斷。
[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】： 青光眼以特征性視神經(jīng)萎縮與視野缺損為臨床特征,是眼科常見眼病,其致盲率可高達(dá)15%~20%,屬于三大致盲眼病之一。在所有青光眼類型中以閉角型青光眼最為常見,可占全部青光眼類型中60%~80%。原發(fā)性閉角型青光眼主要由眼部解剖結(jié)構(gòu)異常導(dǎo)致房角結(jié)構(gòu)狹窄,前房角關(guān)閉,房水排出受阻
