When a normal cornea is examined under a slit-lamp in lateral directions the notable features are the non-scattering epithelium bounded by two narrow bright bands, the stroma in which the scattering is relatively uniform and less intense than in the two bright bands, and a bright band at the endothelium. Other researchers have investigated this distribution of scattering and have concluded that most of the contribution to the integrated scattered intensity from the cornea comes from the limiting layers. In the present study we report our measurements of light scattering vs depth into the cornea over a wide range of scattering angles (20-145°), and show that, at each angle, most of the scattering emanates from the stromal region. This conclusion is based on an analysis which corrects for the distortions introduced by the spatial response function of the measuring apparatus.
