正常人头颅Ｘ线后前位片１５０例测量眼眶内侧壁间距离。男性眶距范围在２４～３５ｍ，平均为２８．８７ｍｍ；女性内眶距范围在２３～３２ｍｍ，平均２７．８８ｍｍ分析４０例；眶距增宽症患者，从临床角度提出中国人眶距增宽症的分度标准，即一度为３２～３６ｍｍ，二度为３６～４０ｍｍ，三度为大于４０ｍｍ。
150 cases of normal head X-ray X-ray measuring the distance between the inner orbital wall. The range of male orbital distance was 24-35 m with an average of 28.87 mm. The female orbital distance ranged from 23-32 mm with an average of 27.88 mm. Forty patients with orbital locomotion widened Symptoms indexing standard, once as 32 ~ 36mm, second degree of 36 ~ 40mm, third degree is greater than 40mm.
