A corneal topogram of the right eye of a patient with keratoconus prior to treatment with asymmetric radial keratotomy.

The image shows the axial curvature of the cornea, with blue areas indicating areas of flattest curvature, and red the steepest curvature. The steep (red) region below the central cross indicates the irregular protruding cone that is characteristic of keratononus.
