Abstract

Many methods have been tried to detect pathological conditions of the cornea using corneal topography. In the approach communicated here certain global parameters derived from topographical information of the anterior corneal surface are shown to create a three dimensional parameter space which can be partitioned so as to divide the general population into sub populations, each of which is well correlated with certain pathological conditions of the cornea or with clinically normal corneas. In addition, these parameter groupings give insight in the structural mechanisms underlying the disorder they identify.
