Effects of corneal epithelial superficial keratectomy in patients with focal limbal stem cell disease

open access: yesAmerican Journal of Ophthalmology Case Reports, 2022
Purpose: Irregular corneal epithelium in limbal stem cell disease can cause visual acuity to deteriorate substantially when it reaches the pupil. In this case series, we assessed the effectiveness of simple corneal epithelial superficial keratectomy in ...

Core transcription regulatory circuitry orchestrates corneal epithelial homeostasis

open access: yesNature Communications, 2021
Corneal epithelium shares similar molecular signatures to other stratified epithelia. Here, the authors map super-enhancers and accessible chromatin in corneal epithelium, identifying a transcription regulatory circuit, including RUNX1, PAX6, and SMAD3 ...

Flow cytometry protocol to quantify immune cells in the separated epithelium and stroma of herpes simplex virus-1-infected mouse cornea

open access: yesSTAR Protocols, 2023
Summary: Existing flow cytometry approaches identify immune cells using the whole infected/inflamed cornea, which limits its ability to distinguish the immune cells infiltrating the corneal epithelium from the corneal stroma.

Low‐intensity low‐frequency ultrasound mediates riboflavin delivery during corneal crosslinking

open access: yesBioengineering & Translational Medicine, 2023
We employed the mechanical effect from 40 kHz ultrasound (US) to improve the delivery of riboflavin into corneal stroma for collagen crosslinking, which can benefit the treatment of keratoconus and other corneal ectasias.
