I use corneal topography to look for early changes in the corneal shape and optics. when looking at these maps, one can either use Placido-based or elevation-based topography, and there are a number of factors to look for: We look at asymmetry of astigmatism, both with regard to inferior-superior differences in steepness and irregularity of the astigmatic bowtie, as well as corneal steepening.
