Corneal Healing

Abstract

Corneal wound healing is a complex procedure that involves apoptosis, migration, proliferation, and differentiation of cells. Several growth factors and cytokines are necessary to perform this process. Due to the avascular nature of the cornea, these growth factors proceed from sources such as tears, inflammatory cells, epithelium, or stroma. Depending on the extent and type of injury, the healing response can produce corneal scarring, with loss of corneal transparency leading to visual impairment.
