 Revisiting keratoconus diagnosis and progression ...

Discussion

The Pentacam software compares the measured values with the means and standard deviations of a normal population, and helps provide color-coded “flags.” For example, measured values which exceed the standard deviation by a factor of more than 2.5 are classified as abnormal and highlighted in yellow, and pathological values, ie, values that exceed the standard deviation by a factor of more than three, are highlighted in red. Namely, these indices are the following:

ISV the unitless standard deviation of individual corneal sagittal radii from the mean curvature. ISV is thus an expression of the corneal surface irregularity. It is elevated in all types of corneal surface irregularity (eg, scars, astigmatism, deformities caused by contact lenses, pachymetry). According to the manufacturer’s user manual,24 an ISV larger than 37 i...
