SCORE display software: the map uses the classical Orbscan Quad Map display. Gets the value of the SCORE corresponds to calculation of a discriminating function established from 12 clues. Optimal cut-off value is zero. In this example, the calculated score of 2.1 suggests the presence of subclinical keratoconus. Map (left eye) was obtained in a patient with advanced keratoconus of the right eye. Despite negative screening based on Placido topography alone (OPD Scan III, Klyce/Maeda indices, Corneal Navigator software), the score was strongly positive. Calculation of the score is based on 12 Placido topography, elevation and pachymetry indexes.
