11 Corneal Thickness
To test the hypothesis that the CTSP and PIT increase sensitivity for the detection of very early forms
of keratoconus we studied patients with keratoconus in one eye and in the other a cornea of normal
surface curvature as evidenced by Placido topography. Interestingly, the contra-lateral eyes also
exhibited signs of abnormality on the CTSP and PIT graphs
