基于CT的骨性眶缘及眼球相对位置与衰老关系的研究
A CT-Based Study of the Relationship between the Bony Orbit and the Relative Position of the Eyeballs and Ageing

目的：探索骨性眶缘形态及眼球相对位置在不同年龄组及不同性别间的差异，为眶周年轻化的诊疗提供理论依据。方法：收集126例成年人颅脑CT资料并进行三维重建，男性和女性患者各分为青年组(女性21例，男性20例)、中年组(女性23例，男性21例)、老年组(女性21例，男性20例)，使用Image J软件对各组骨性眶缘面积、眶缘宽度、眶缘高度、眼球中点到眶上缘垂直距离和眼球中点到眶上缘垂直距离进行测量，收集数据并进行统计学分析。结果：各年龄组男性与女性骨性眶缘面积差异无统计学意义；男性眶缘宽度随年龄增长而逐渐减小，青年组、中年组、老年组眶缘宽的平均值分别为3.58 ± 0.16 cm、3.50 ± 0.13 cm、3.45 ± 0.14 cm，女性眶缘宽度则无明显改变；男性与女性眶缘高度随年龄无明显改变；男性与女性眼球中点到上眶缘的垂直距离随年龄增大逐渐增大，男性各年龄组的平均值分别为1.51 ± 0.08 cm、1.59 ± 0.16 cm、1.58 ± 0.09 cm，女性各年龄组的平均值分别为1.51 ± 0.10 cm、1.57 ± 0.11 cm、1.58 ± 0.09 cm，而眼球中点到眶下缘的垂直距离则在男性和女性中均呈现减小的趋势，该差异主要发生于中年。结论：男性与女性骨性眶缘面积、眼眶高度随年龄增大无明显改变，男性眶缘宽度呈现随年龄增长而增大的趋势，女性眶缘宽度改变则无统计学意义。男性与女性均随年龄出现眼球相对位置下降的趋势。
Purpose: The aim of this study is to investigate the differences of skeletal orbital margin morpholo-gy and relative position of eyeball in different age groups and different genders, and to provide theoretical basis for the diagnosis and treatment of periorbital rejuvenation. Methods: The data of 126 adult brain CT cases were collected and reconstructed in 3D. Male and female patients were each divided into a young group (21 females, 20 males), a middle-aged group (23 females, 21 males), and an elderly group (21 females, 20 males). The bony orbital area, orbital width, orbital height, vertical distance from the midpoint of the eyeball to the superior orbital rim and vertical distance from the midpoint of the eyeball to the inferior orbital rim were measured using Image J software, and the data were collected and analyzed statistically. Results: There was no statistically significant difference in the bony orbital area between males and females in each age group. The orbital width in males decreased gradually with age, and the mean values of the orbital width in the young, middle-aged, and old age groups were 3.58 ± 0.16 cm, 3.50 ± 0.13 cm, and 3.45 ± 0.14 cm, respectively, but did not change significantly in females. The orbital height in males and females did not change significantly with age. The vertical distance from the midpoint of the eyeball to the su-perior orbital rim gradually increased with age in both males and females, with mean values of 1.51 ± 0.08 cm, 1.59 ± 0.16 cm, and 1.58 ± 0.09 cm in males and 1.51 ± 0.10 cm, 1.57 ± 0.11 cm, and 1.58 ± 0.09 cm in females in all age groups, respectively, and the vertical distance from the midpoint to the inferior orbital rim in both males and females. The vertical distance from the midpoint of the eyeball to the inferior orbital rim showed a tendency to decrease in both males and females, with the difference occurring mainly in middle age. Conclusion: There were no significant
