Corneal ulcer, also called keratitis, is an inflammatory or, more seriously, infective condition of the cornea involving disruption of its epithelial layer with involvement of the corneal stroma.[1][2][3] It is a common condition in humans particularly in the tropics and in farming.[4] In developing countries, children afflicted by vitamin A deficiency are at high risk for corneal ulcer and may become blind in both eyes persisting throughout life. In ophthalmology, a corneal ulcer usually refers to having an infection,[2] while the term corneal abrasion refers more to a scratch injury.[5]
