Scratching the Surface: Diagnosis and Management of Corneal Ulcers
نویسنده
چکیده
The cornea is composed of 4 main layers: the epithelium, stroma, Descemet’s membrane, and the endothelium. The cornea is a highly innervated structure containing branches from the trigeminal nerve (CN V), which provides large nerve plexi that extend throughout the stroma and epithelium. The cornea is normally avascular, obtaining its nutrients from the tear film externally, and the aqueous humor internally.
