OCULUS Pentacam Interpretation Guide

10.10 Asymmetric keratoconus
This is a 4 Maps Selectable display (Figure 70) of a normal astigmatic eye (OD) with a thin cornea
(thinnest reading 483 μm) and a noteworthy abnormality in the pachymetry distribution with a
significant inferior-temporal displacement of the thinnest zone. At times the only indicator of
potential pathology may be the magnitude and distribution of the corneal pachymetry.
DIAGNOSIS - asymmetric keratoconus greater in OS than OD
