Gross factors in treatment of nonhealing corneal ulcers and recurrent erosions.

| Abstract |
Epidermal growth factor (EGF) is known to promote corneal epithelial wound healing in experimental scrape and keratectomy models. We studied its efficacy in treating alkali-burned epithelial ulceration. EGF induced hyperplasia and cell proliferation to resurface the denuded and denatured corneal stroma, but it did not prevent recurrent erosions. A combination of EGF with fibronectin (Fn) was noted to enhance epithelial defect closure after alkali burns of the cornea and was seen to prevent recurrent erosions. Histopathologic examination of these corneas revealed marked leukocytic infiltration of the alkali-burned corneal stroma. To find ways to retard this inflammatory response, we studied the role of topical steroids and their efficacy when used with EGF, Fn, and laminin (Ln) in the management of alkali-burned corneas. Use of steroids decreased the incidence of recurrent erosions and corneal perforations. Histologically, steroids markedly decreased the leukocytic infiltration of stromal tissue, thereby retarding the collagenolysis. Topical steroids used with EGF and fibronectin were seen to promote epithelial wound closure and to prevent recurrent erosions in alkali-burned corneas. Combinations of EGF, fibronectin, and steroids may have a place in the treatment of clinical corneal alkali burns.
