角膜和巩膜厚度和前房尺寸是了解发育和病理过程所必需的。眼球的参数也需要计算光学和材料特性。由于眼球类似于压力容器，因此有人建议可以从厚度的测量来计算角膜和巩膜的弹性。使用Visante OCT（光学相干断层扫描）在新鲜猪眼中测量基线角膜和巩膜厚度以及前房尺寸以及这些如何随着眼内液体的增量增加而变化。在基线时，角膜厚度几乎是恒定的。前巩膜厚度是可变的，从利姆布斯附近的0.91+/-0.07 mm减少到最小值0.58+/-0.13。后巩膜厚度更稳定，平均为0.78+/-0.09 mm。视神经附近厚度增加至1.00+/-0.09 mm。前房角、直径和深度的平均基线分别为33.15+/-4.91 deg、13.60+/-0.38 mm和2.13+/-0.22 mm。液体注射后，角膜和巩膜厚度的最大变化分别为9 - 10%和1 - 3%。前房角和深度轻微但显著降低。通过对注射液体后眼球表面的变化进行分析，表明压力容器模型可以应用于计算角膜和巩膜的弹性。
Corneal and scleral thickness and anterior chamber dimensions are required for understanding developmental and pathological processes. Parameters of the eyeball are also required to calculate optical and material properties. As the eyeball resembles a pressure vessel, it has been suggested that elasticity of the cornea and sclera could be calculated from the measurements of thickness. Baseline corneal and scleral thicknesses and anterior chamber dimensions and how these change with incremental increases of intraocular fluid are measured in fresh porcine eyes using the Visante OCT (optical coherence tomography). At baseline, corneal thickness is almost constant. Anterior scleral thickness is variable, decreasing from 0.91+/-0.07 mm near the limbus to a minimum of 0.58+/-0.13. Posterior scleral thickness is more constant with an average of 0.78+/-0.09 mm. Near the optic nerve the thickness increases to 1.00+/-0.09 mm. Average baseline anterior chamber angle, diameter, and depth were found to be 33.15+/-4.91 deg, 13.60+/-0.38 mm, and 2.13+/-0.22 mm, respectively. After fluid injections, maximum changes in corneal and scleral thicknesses were 9 to 10 and 1 to 3%, respectively. Anterior chamber angle and depth decreased slightly but significantly. Changes in the eyeball coats with fluid injections, indicate that the pressure vessel model can be applied to the eye to calculate corneal and scleral elasticities.
