Results of comparative ex vivo measurements of backscattering from rabbit cornea made by optical coherency tomography and confocal microscopy strongly suggests the existence of small angle backscattering from the cornea. Apparently, this is associated with a zero order peak of diffraction on the corneal fibril "lattice" structure, which was first suggested by D. Maurice in 1957 as a physical basis of corneal transparency. By using water suspension of polystyrene spheres as a scattering standard, absolute values of backscattering coefficients of normally hydrated cornea for wide and small angle backscattering and degree of fibrils arrangement could be estimated. |
