12 Belin/Ambrósio Enhanced Ectasia Display
Figure 110: Belin/Ambrósio Enhanced Ectasia Display (version II) of a normal highly
astigmatic eye
Both anterior and posterior elevations are normal and show a typical astigmatic pattern. The central
cornea has a normal thickness at the apex of 532 μm but shows little progression towards the
periphery causing the PIT tracing to be relatively flat (opposite of what you would see in ectasia).
The TP is moderately displaced (Dy = 1.89 SD), but the overall reading "D" value is within the normal
range.
