Correlation of corneal epithelial thickness with clinical severity of dry eye

African Vision and Eye Health, 2023
Background: Spectral-domain optical coherence tomography (OCT) has been used to measure corneal epithelium thickness in dry eye disease, allowing assessment of ocular-surface damage in different disease severity.

Dissecting the Profile of Corneal Thickness With Keratoconus Progression Based on Anterior Segment Optical Coherence Tomography

Frontiers in Neuroscience, 2022
PurposeTo characterize the corneal and epithelial thickness at different stages of keratoconus (KC), using a deep learning based corneal segmentation algorithm for anterior segment optical coherence tomography (AS-OCT).MethodsAn AS-OCT dataset was ...

Heidelberg Anterion Swept-Source OCT Corneal Epithelial Thickness Mapping: Repeatability and Agreement With Optovue Avanti [PDF]

, 2022
PURPOSE: To assess the repeatability of corneal epithelial thickness mapping in virgin, post-laser refractive surgery (PLRS), and keratoconic eyes using a novel swept-source optical coherence tomographer (SS-OCT), and to determine the agreement of the

The transcriptome of wild-type and immortalized corneal epithelial cells [PDF]

, 2021
Cellular immortalization enables indefinite expansion of cultured cells. However, the process of cell immortalization sometimes changes the original nature of primary cells.

The Influence of Tomographic Corneal Characteristics on Epithelial Thickness Profile [PDF]

Cureus, 2020
Purpose To understand the influence of tomographic corneal characteristics on the epithelium of normal eyes. Methods We scanned a total of 98 eyes of 98 individuals using anterior segment tomography and a spectral-domain optical coherence tomography (OCT) epithelial mapping tool.

Applications of epithelial thickness mapping in corneal refractive surgery

Saudi Journal of Ophthalmology, 2022
In this review, we discuss the applications of epithelial thickness mapping in corneal refractive surgery. The review describes that the epithelial thickness profile is nonuniform in the normal eye, being thinner superiorly than inferiorly and thinner temporally than nasally.

Scaling and maintenance of corneal thickness during aging. [PDF]

PLoS ONE, 2017
Corneal thickness is tightly regulated by its boundary endothelial and epithelial layers. The regulated set-point of corneal thickness likely shows inter-individual variations, changes by age, and response to stress.
