Borderline Case Of Keratoconus - OCULUS Pentacam Interpretation Manual

10 Screening for refractive surgery

10.7 Borderline case of keratoconus

This 4 Maps Selectable display (Figure 65) shows a low-grade paracentral island (maximal
elevation in island + 8 μm) in the anterior elevation map and a diffuse oval island on the posterior
surface (maximal elevation in island + 16 μm). The anterior values are within the normal range,
while the posterior numbers are just outside the normal range. The pachymetry map is normal,
revealing a thick cornea (thinnest region 608 μm) with a normal pachymetry distribution. The
completely normal pachymetry map suggests that the borderline elevation changes are probably
acceptable.
