Subclinical keratoconus detection by pattern analysis of corneal and epithelial thickness maps with optical coherence tomography.

Purpose: To screen for subclinical keratoconus by analyzing corneal, epithelial, and stromal thickness map patterns with Fourier-domain optical coherence tomography (OCT).

Setting: Four centers in the United States.

Design: Cross-sectional observational study.

Keratoconus diagnosis with optical coherence tomography–based pachymetric scoring system.

Purpose: To develop an optical coherence tomography (OCT) pachymetry map–based keratoconus risk scoring system.

Settings: Doheny Eye Institute, University of Southern California, Los Angeles, California, and Brass Eye Center, New York, New York, USA; Department of Ophthalmology, Affiliated Eye Hospital of Wenzhou Medical College, Wenzhou, China.

Design: Cross-sectional study.

Corneal epithelial thickness mapping by Fourier-domain optical coherence tomography in normal and keratoconic eyes.

Objective: To map the corneal epithelial thickness with Fourier-domain optical coherence tomography (OCT) and to develop epithelial thickness-based variables for keratoconus detection.

Design: Cross-sectional observational study.

Participants: One hundred forty-five eyes from 76 normal subjects and 35 keratoconic eyes from 22 patients.
