Epithelial thickness mapping for corneal refractive surgery
Current Opinion in Ophthalmology, 2022Purpose of review As more devices become available that offer corneal epithelial thickness mapping, this is becoming more widely used for numerous applications in corneal refractive surgery. Recent findings The epithelial thickness profile is nonuniform in the normal eye, being ...

Utility of regional epithelial thickness measurements in corneal evaluations
Survey of Ophthalmology, 2020The measurement of regional corneal epithelial thickness and characterization of its behavior in response to changes in corneal architecture are increasingly drawing interest in clinical practice. The epithelium has tremendous capacity for remodeling and does so in response to underlying stromal pathology or changes in anterior corneal curvature ...

Role of corneal epithelial thickness mapping in the evaluation of keratoconus
Contact Lens and Anterior Eye, 2019To investigate the corneal epithelial thickness profiles in patients with a confirmed diagnosis of stable and progressive keratoconus.Studio Italiano di Oftalmologia, Rome, Italy.Observational study.86 patients with either stable (n = 52) or progressive (n = 34) keratoconus and 182 healthy controls were enrolled in the study.

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.
