Corneal ulcer

Corneal ulcer or ulcerative keratitis is an inflammatory or infective condition of the cornea involving disruption of its epithelial layer with involvement of the corneal stroma. It is a common condition particularly in the tropics and the agrarian societies. In developing countries, children afflicted by vitamin A deficiency are at high risk of corneal ulcers and may become blind in both eyes. In ophthalmology, a corneal ulcer usually refers to having an infectious etiology while the term corneal abrasion refers more to physical abrasions.
