COMPARISON OF CORNEAL MEASUREMENTS IN NORMAL AND KERATOCONUS EYES USING ANTERIOR SEGMENT OPTICAL COHERENCE TOMOGRAPHY AND PENTACAM HR TOPOGRAPHER

COMPARISON OF CORNEAL MEASUREMENTS IN NORMAL AND KERATOCONUS EYES USING ANTERIOR SEGMENT OPTICAL COHERENCE TOMOGRAPHY AND PENTACAM HR TOPOGRAPHER

The purpose of current study is to provide a comprehensive comparison of the reliability of corneal topographic measurements between Optovue AS- OCT and a combined Scheimpflug imaging using Wavelight Oculyzer Pentacam HR in normal and keratoconus eyes.

Inclusion Criteria:

• topography characteristic of keratoconus (skewed asymmetric bow-tie, inferior steep spot, etc.) and at least one clinical sign e.g., slit lamp findings of Munson's sign, Vogt's striae, Fleischer's ring, apical thinning, Rizutti's sign, etc.

Exclusion Criteria:

• are advanced complications of keratoconus such as corneal scars or hydrops.
