Why the cornea ulcerates, in the sense of what goes awry, may be related to the trapping of wound healing in a phase of proteolytic debridement related to a persistent epithelial defect. The initial avascularity of the cornea makes it particularly vulnerable to proteolytic damage. Studies on the biochemistry and cell biology of corneal ulceration have indicated that sequential interactions occur which result in the generation of collagenase activity and the development of ulceration. It is likely that the interactions are susceptible to intervention; and it is thought that eventual, successful treatment of corneal ulceration will require a complex therapy, with interventions at multiple sites of regulation.
