Distribution of the scattered light from the cornea has been determined, using a phototube of multiplier type.
A slight scattering occurs in the forward direction even in the transparent cornea. In the peripheral region of the cornea, the scattering in the direction right angles to the radial fibers is greater than that in the parallel direction. In the central region, no directional difference is found in the scattering characteristics.
As the cornea clouds, the scattering increases in the backward and lateral directions, though the greater parts of the scattering occur in the forward direction.
On drying the cornea, the transparency of the clouded or fresh cornea is recovered or even enhanced.
The transparency and clouding of the cornea are explained in terms of interference in the double lattice structure consisting of the fibers and the fibrils.
The changes in the microscopic lattice are revealed in the diffraction spectra and the polarization findings. On the other hand, the changes in the submicroscopic lattice are revealed in the angular intensity distribution of the scattered light.
