UNLABELLED: PURPOSETo review the topographic patterns associated with keratoconus suspects and provide criteria for keratoconus screening.
METHODS: Case study using maps from the NIDEK OPD-Scan II and OPD Station to highlight patterns seen in keratoconic corneas.
RESULTS: Five criteria are listed for the detection of keratoconus: 1) apex of the cone is not centered at the 6-o'clock semi-meridian, 2) cone should appear round on the tangential map, 3) keratometry >45.00 diopters, 4) corneal thickness at the apex of the cone is approximately 30 microm thinner than the corresponding distance above the pupil center, and 5) topographic patterns are not symmetric.
CONCLUSIONS: Standard corneal topography maps and simple clinical evaluation criteria are fundamental to detect keratoconus suspects and keratoconus.
