12 Belin/Ambrósio Enhanced Ectasia Display
Figure 111: Belin/Ambrósio Enhanced Ectasia Display (version II) of a cornea with an
isolated suspicious area on the posterior cornea
The anterior elevation shows a very low degree of astigmatism, and the pachymetric progression,
thinnest value and TP displacement are all within normal limits. The posterior elevation change is
further heightened by the enhanced reference surface, and the bottom display for the posterior
elevation reveals a yellow zone. The Db is 2.27 SD from the mean which puts this in the yellow zone,
but because this is an isolated finding the final overall reading "D" is still within normal range at
0.55 SD.
