The corneal scarring is the result of the initial invasion of blood vessels into the corneal stroma as part of the inflammatory response. Since normal corneal tissue should be avascular (no blood vessel) and therefore clear to allow light to pass, the presence of blood vessel and the infiltration of cells as part of the inflammatory process results in scarring or hazing of the cornea.
Peripheral Ulcerative Keratitis (PUK) is a group of destructive inflammatory diseases involving the peripheral cornea in human eyes. [1] The symptoms of PUK include pain, redness of the eyeball, photophobia, and decreased vision accompanied by distinctive signs of crescent-shaped damage of the cornea.
