To measure eye and orbit anthropometric variation within the normal population by using CT images and to determine the effects of age and sex on eye and orbit anthropometry. Quantification of eye and orbit anthropometric variation within the normal population and between persons of different age and sex is important in the prediction and prevention of eye injury.
A systematic method was developed to align head CT images three dimensionally and to measure ocular and orbital parameters in 39 subjects. Twenty-four measurements were collected along the orbital rim, to quantify the orbital aperture. Protrusions of the brow and the eye were measured, along with relative distances, to describe location of the eye within the orbit.
The orbit widened with age, and significant relations were identified between orbital aperture and eye location measurements, both of which varied significantly between the sexes.
The comprehensive set of measurements collected in this study provides three-dimensional information on orbit geometry, as well as placement of the eye within the orbit. These measurements and the methodology used will contribute to the development of finite element models of the orbit and eye for computational modeling purposes and may be useful in the design of eye protection equipment.
通过使用CT图像测量正常人群的眼睛和眼眶人体测量学变异，并确定年龄和性别对眼睛和眼眶人体测量学的影响。量化正常人群以及不同年龄和性别的人群之间眼睛和眼眶人体测量学变异，对于眼外伤的预测和预防具有重要意义。
开发了一种系统方法，用于对头部CT图像进行三维对齐，并测量39名受试者的眼部和眼眶参数。沿着眶缘进行了24次测量，以量化眶口大小。测量了眉部和眼睛的突出度以及相对距离，以描述眼睛在眼眶内的位置。
眼眶随着年龄增长而变宽，并且在眶口大小和眼睛位置测量之间发现了显著关系，这两者在性别之间均有显著差异。
本研究收集的全面测量数据提供了关于眼眶几何形状以及眼睛在眼眶内位置的三维信息。这些测量数据和所使用的方法将有助于开发用于计算建模目的的眼眶和眼睛有限元模型，并且可能有助于眼部防护设备的设计。
