To compare the differences between Hertel exophthalmometry and CT on exophthalmos measurement, and explore its practical application value in forensic medicine.
Fifty-six normal individuals without eye injuries or diseases were selected as the control group. The absolute values of exophthalmos were measured in the standardized CT image workstation. The difference of binocular exophthalmos was compared in normal group. Forty-seven cases with unilateral orbital fracture were divided into injured eye group and normal eye group according to the presence of binocular orbital fractures. The differences of the absolute values of eophthalmos from the same eye and the relative values of eophthalmos between two eyes for same person measured by Hertel exophthalmometry and CT were analyzed.
There was no statistical difference of exophthalmos between the normal eyes measured by CT method. In the normal eye group, the absolute value of exophthalmos measured by CT method was （16.66±5.41） mm, which was （16.16±4.45） mm when measured by the Hertel exophthalmometry method. There was no statistical difference between two groups （>0.05）. In the injured eye group, there was statistical difference between the absolute values of exophthalmos measured by two measurement methods （ <0.05）. There was no statistical difference of the relative values of exophthalmos between the injured eyes and the normal eyes by two measurement methods （>0.05）.
CT method has a good consistency with Hertel exophthalmometry, which can be applied into the practice of medicolegal expertise.
比较Hertel眼球突出计与CT测量眼球突出度的差异，探讨其在法医学中的实际应用价值。
选取56例无眼外伤及眼病的正常个体作为对照组，在标准化CT图像工作站测量眼球突出度绝对值，比较正常组双眼眼球突出度差值。将47例单侧眼眶骨折患者按有无双眼眶骨折分为伤眼组和健眼组，分析Hertel眼球突出计与CT测量同一人同一眼眼球突出度绝对值及双眼眼球突出度相对值的差异。
CT测量正常眼眼球突出度差异无统计学意义。正常眼组中，CT测量眼球突出度绝对值为（16.66±5.41）mm，Hertel眼球突出计测量值为（16.16±4.45）mm，两组比较差异无统计学意义（>0.05）。伤眼组中，两种测量方法测量眼球突出度绝对值差异有统计学意义（<0.05）。两种测量方法测量伤眼与健眼眼球突出度相对值差异无统计学意义（>0.05）。
CT测量法与Hertel眼球突出计测量结果一致性良好，可应用于法医学鉴定实践。
