Computed tomographic digital data and special off-line computer graphic analysis were used to measure volumes of normal orbital soft tissue, extraocular muscle, orbital fat, and total bony orbit in vivo in 29 patients (58 orbits). The upper limits of normal for adult bony orbit, soft tissue exclusive of the globe, orbital fat, and muscle are 30.1 cm3, 20.0 cm3, 14.4 cm3, and 6.5 cm3, respectively. There are small differences in men as a group compared with women but minimal difference between right and left orbits in the same person. The accuracy of the techniques was established at 7%-8% for these orbit structural volumes in physical phantoms and in simulated silicone orbit phantoms in dry skulls. Mean values and upper limits of normal for volumes were determined in adult orbital structures for future comparison with changes due to endocrine ophthalmopathy, trauma, and congenital deformity.
利用计算机断层扫描数字数据和特殊的离线计算机图形分析，对29例患者（58只眼眶）的正常眼眶软组织、眼外肌、眶脂肪和整个骨性眼眶的体积进行了活体测量。成人骨性眼眶、不包括眼球的软组织、眶脂肪和肌肉的正常上限分别为30.1立方厘米、20.0立方厘米、14.4立方厘米和6.5立方厘米。作为一个群体，男性与女性之间存在细微差异，但同一个人的左右眼眶之间差异极小。在物理模型和干燥颅骨中的模拟硅胶眼眶模型中，这些眼眶结构体积的测量技术准确性确定为7%-8%。确定了成人眼眶结构体积的平均值和正常上限，以便将来与内分泌性眼病、外伤和先天性畸形引起的变化进行比较。
