Abstract Details

Purpose:

To enhance keratoconus diagnosis accuracy with the correlation of several anterior segment diagnostic techniques and applying novel parameters.

Setting:

The Laservision Clinical and Research Institute, Athens, Greece

Methods:

250 keratoconic cases were evaluated for keratoconic grading and anterior surface indexing by Scheimpflug imaging (Oculyzer , WaveLight AG, Erlagen, Germany), Placido Topography (Vario Topolyzer, WaveLight AG), and Anterior Segment-OCT (RTVue-100, Optovue Inc., Fremont, CA).The correlations between Scheimpflug- and Placido- derived keratoconic grading and anterior-surface irregularity indices for keratoconus, as well as epithelial thickness distribution characteristics were assessed with the AS-OCT and the MSRT-derived keratoconus indices employing paired two-tailed t-tests, Bland-Altman plots, coefficient of determination (r2), and trend line linearity.

Results:

Scheimpflug- and Placido- derived keratoconic grading and anterior-surface irregularity indices for keratoconus with the AS-OCT and the Topography - derived keratoconus was observed. Increased topographic thickness variability and range was found to be in correlation with keratoconus severity, quantitatively expressed with Scheimpflug imaging-derived anterior-surface irregularity indices.

Conclusions:

Advanced corneal diagnostics correlation may enhance the accuracy of early keratoconus diagnosis
