Abstract
The light scattered by a cornea occurs mainly at small angles. The patterns obtained experimentally showed a characteristic maxima at 0° angles and a four lobe 0—90° pattern in the I+ mode and a two lobe 0—180° pattern in the I|| mode. A model system is presented here in which anisotropic rods (collagen fibrils) embedded in an isotropic medium (ground substances) form a two-dimensional assembly (lamellae) which are stacked in a nonrandom fashion (stroma). The light-scattering patterns from such a model system were calculated by varying a number of parameters, such as the length of the rod, its average orientation, etc. Thus the role of each parameter in the model in influencing light-scattering patterns in I+ and I|| mode was evaluated. Finally, the computer-simulated patterns were matched to the experimental patterns and the numerical values of the parmeters of the model were obtained.
