通过对１２０ 例正常成年国人眼球突出度的ＣＴ测量，建立正常值范围。所有病例均以ＯＭ 基线进行轴状位３ ｍ ｍ 薄层扫描。选择眼球最大径层面，在该层面做两侧眶外侧缘骨壁前端连线，测量角膜前缘顶点到该连线的垂直距离。同时观察５０例Ｇｒａｖｅｓ眼病的眼球突出程度。结果显示：角膜前缘顶点到两侧眼眶外缘连线的垂直距离平均值１２４ ｍ ｍ ，正常值范围为９９～１４．９ ｍ ｍ 。根据５０ 例Ｇｒａｖｅｓ眼病患者眼球突出程度，把眼球突出划分为Ⅰ度和Ⅱ度 Through the normal adult 120 cases of eyeball projection CT measurement to establish the normal range. All cases were scanned by OM 3-slice thin slice scanning. Select the maximum diameter of the eye level, at this level to do both sides of the lateral orbital margin of the anterior border of the bone wall to measure the vertex of the corneal anterior vertex to the vertical distance. At the same time observe 50 cases of Graves eye disease, the extent of the eyeballs. The results showed that the average distance between the vertex of the anterior cornea and the outer rim of the orbital rim was 124 m m and the normal range was 99 ~ 14.9 m m. According to 50 patients with Graves eye disease in patients with prominent extent of the eye, the eye is divided into Ⅰ and Ⅱ degrees
