Disease Roles
Corneal Epithelium Overview
The corneal epithelium is the outermost layer of the cornea, composed of non-keratinized stratified squamous epithelial cells. It serves as a critical barrier protecting the eye from environmental insults, pathogens, and fluid loss. This layer also plays a role in maintaining corneal transparency and contributes to ocular surface homeostasis. Damage or disease affecting this layer can result in pain, impaired vision, and increased infection risk.
