超声波检查是利用高频率声波的回声进行检查,自1956年首次应用于眼科,现已成为眼及眼眶疾病的重要诊断方法。这种检查方法简单易行,并对病人无损害。可显示眼球及眼眶内组织的横断面,区别几种组织的特点。故当屈光间质不清或病变位于视线不可见的地方,超声波检查显得尤为重要。此外,超声波可精确地测量某些组织的厚度或距离。 Ultrasound is the use of high-frequency acoustic echo examination, first applied to ophthalmology since 1956, has now become an important diagnostic method of eye and orbital disease. This method of checking is simple and does not harm the patient. Can show the eye and orbital tissue cross-section, the difference between the characteristics of several organizations. Therefore, when the refractive interstitial or lesions are not visible in the sight of the place, ultrasound is particularly important. In addition, ultrasound can accurately measure the thickness or distance of certain tissues.
