Baun等(1963)首先将超声扫描应用于眼眶疾病的检查。超声为高频声波,故对病人无放射性或其它危害。因此,超声可用来重复检查患者并对复发者进行随诊。这一方法对眶尖部或眶顶部的病变用途很小。电脑断层扫描(CT)发明于1972年,已替代了许多对病人有害的检查技术。CT的优越性在于能探查出组织密度的微小差异,并能确定病变 Baun et al. (1963) first applied ultrasound scans to eyelid diseases. Ultrasound is a high-frequency sound wave, so there is no radiation or other hazards to the patient. Therefore, ultrasound can be used to repeat the examination of patients and followed up for relapsers. This method is of little use for lesions at the tip of the hernia or at the top of the hernia. Computed tomography (CT) was invented in 1972 and has replaced many inspection techniques that are harmful to patients. The superiority of CT lies in the ability to detect small differences in tissue density and identify lesions.
