ABSTRACT
Epidermal growth factor (EGF) has been believed to promote the corneal epithelial wound healing by stimulating the proliferation of the epithelial cells located at the wound base and limbus. Thus we made transepithelial photokeratectomy by excimer laser to cornpare the rate of corneal wound healing and the histological findings between a group received only photokeratectomy (control) and a group with photokeratectorny and topical EGF treatment. The results showed that the corneal epithelial wounds treated with EGF after excimer laser photokeratectomy was closed significantly faster than those without. EGF, PCNA immunoreactive cells appeared at. the basal cell layer of limbus and wound area in EGF-treated groups but, not, in control group These resuite suggest that EGF accelerates the corneal epithelial wound healing after excimer laser photokeratectomy by stimulating the proliferation of the basal cells of limbus and wound area and results in 8 faster wound healing time.
