Corneal Epithelial Thickness Profile in the Diagnosis of Keratoconus
Journal of Refractive Surgery, 2009Purpose: To illustrate the hypothesis that epithelial thickness profile maps could be used as an adjunctive tool to improve the sensitivity and specificity of keratoconus screening by presenting a case series of examples. Methods: The Artemis very high-frequency digital ultrasound ...

Systematic detection of keratoconus in OCT: corneal and epithelial thickness maps
Journal of Cataract & Refractive Surgery, 2022Purpose: To detect keratoconus (KC) only by analyzing the corneal and epithelial map parameters and patterns in optical coherence tomography (OCT). Setting: Tertiary care refractive surgery center. Design: Retrospective data collection.

Correlation of Sex and Myopia With Corneal Epithelial and Stromal Thicknesses
Cornea, 2016To measure the corneal epithelial thickness (CET) and stromal thickness (ST) in normal subjects, and to also evaluate their correlation with gender, age, and myopia severity.A total of 162 normal subjects were enrolled; they were divided into 3 groups based on their refractive status: "low myopia" (-0.25 to -3.0 D), "moderate myopia" (-3.0 to -6.0 D ...

Relation of Epithelial Ion Transport to Corneal Thickness and Hydration
Nature, 1968THE control of corneal thickness is a complex process involving the chemistry of the stromal tissue and the barrier properties of the two bounding membranes. Fluid dynamics are intimately involved, for corneal thickness is linearly related to hydration1, which in turn is affected by ion transport.

Corneal Epithelial Thickness Mapping After Photorefractive Keratectomy for Myopia
Journal of Refractive Surgery, 2019PURPOSE: To evaluate the longitudinal changes in epithelial thickness after photorefractive keratectomy (PRK) and correlate these with refractive changes. METHODS: This prospective study included 52 eyes of 52 candidates for myopic PRK.

The role of corneal epithelial thickness map in detecting early keratoconus
Graefe's Archive for Clinical and Experimental OphthalmologyTo detect subtle changes in early keratoconus by evaluating corneal epithelial thickness differences among patients with binocular very asymmetric ectasia (VAE) and normal subjects.Corneal epithelial thickness was measured using the Fourier-domain AS-OCT system RTVue® 100 (Optovue, Fremont, CA, USA).
