Progression rate indices are needed that rely less on macroscopic dataSo, what’s new? Dr Touboul finds the development of pachymetry mapping promising. “Using OCT, corneal structure can be analysed by separating stromal changes and epithelial compensation, making this modality very interesting. The dominant method to rate progression is topographical and tomographical analysis,” said Dr Touboul. This is strongly correlated with worsening of keratoconus in terms of biomechanics, retinal image quality as defined by the point spread function, and with quality of life. Indeed, the decision to intervene in order to halt progression surgically is best made based on this morphological metric, he said. But clinicians cannot focus too much on a single metric. Defining keratoconus progression rates requires the analysis of the entire patient’s profile. There is no magic number to determine therapeutic indications, he emphasised.
