PURPOSE/METHODS: We studied a mild case of keratoconus, which had biomicroscopic evidence of keratoconus. With videokeratoscopy, we examined a 55-year-old man with a family history of keratoconus who showed biomicroscopic evidence of bilateral keratoconus.
RESULTS/CONCLUSIONS: Videokeratoscopy of the least affected eye showed a map pattern consistent with an inferiorly displaced cone, but surprisingly the apex power measured only 45.5 diopters. Patients with apex power as low as 45.5 diopters can show biomicroscopic evidence of keratoconus. If a central database existed for such unusual cases, eye-care specialists could contribute to it and provide valuable material to researchers trying to improve automated methods to differentiate between normal and keratoconic corneas.
