Abstract
Color-coded corneal topographic information contained in a polar plot of plurality of different traces taken over the corneal surface, such as that disclosed in the U.S. Pat. 4,863,260, is reprocessed to present the color topographic map in a 'hills and valleys', Cartesian coordinate display; polar position being presented along the x-axis and elevation being presented along the y-axis. The different circular traces are separated one from the other in a perspective dispersion to emphasize the elevation data with the more apical traces being presented at one end and the more limbal trace being presented at the other end of the perspective dispersion.
