【摘要】 超声检查和测量的准确性对眼部疾病的诊断有着重要意义。常用的眼超声检查主要包括A型超声、B型超声、超声生物显微镜(UBM)和彩色多普勒血流成像等方法。A型超声主要用于测量不同回声强度的组织之间的距离。B型超声可以显示眼的二维结构并对目标点进行定量测量。UBM是一种超高频的二维成像方法，可清晰显示眼前段的结构特点并测量相关参数，对房角形态改变的定量分析，眼内镜植入手术前、后的眼前段形态变化均可提供帮助。彩色多普勒血流成像在二维超声的基础上应用多普勒效应可定量测量移动物质的相关参数，反映眼局部的血流变化情况。为规范不同超声检查方法在眼部检查中的测量操作，特制定本指南。本指南主要针对不同类型眼部超声仪器测量的规范化操作及其在眼部疾病中的临床应用来进行阐述，从而为相关眼部疾病的诊断和治疗提供一定的指导意见。更多还原

【Abstract】 The accuracy of ultrasound examination and measurement is of great significance to diagnosing ocular diseases. The commonly used ocular ultrasonography includes amplitude(A)-mode ultrasound, brightness(B)-mode ultrasound, ultrasound biomicroscopy(UBM), and color Doppler flow imaging(CDFI). A-mode ultrasound is mainly used to measure the distance between tissues with different echo intensities. B-mode ultrasound can visualize the two-dimensional structure of the eye and make quantitative measurements of the target point. UBM is an ultra-high-frequency two-dimensional imaging method, which can clearly display the structural characteristics of the anterior segment and measure the relevant parameters. It can also help quantitatively analyze the morphological changes of the angle and the anterior segment before and after implantable collamer lens surgery. CDFI can quantitatively measure the parameters of blood vessels by applying the Doppler effect on the basis of two-dimensional ultrasound, reflecting the changes of blood flow in the eye. To standardize the operations of different ultrasound examination methods, this guideline is formulated. This guideline mainly focuses on the standardized operation of ocular ultrasound instruments and their clinical application in ocular diseases, so as to provide guidance for the diagnosis and treatment of related ocular diseases.更多还原
