Previous in vivo studies evaluating the effects of growth factors on epithelial regeneration have used the scrape injury model in rabbit eyes. Since growth factors act principally on the mitotic activity of regenerating cells, the rapid wound closure rates following scrape injury may not adequately access the effects of these agents on epithelial repair. In this study, we evaluated the rates of wound healing following scrape (8.6 mm) and lamellar keratectomy (8.6 mm) injury in 25 albino rabbits. Eyes were left untreated or received daily application (two to three times) of (a) Tears Naturale II, (b) 50 mM Tris/NaCl, and (c) commercial vehicle for EGF. Eyes were evaluated daily by fluorescein staining with Ophthalmic Fluoro-Strips followed by clinical photography. The area of staining was quantitated by computer-assisted planimetry and rates calculated by linear regression analysis. Eyes receiving scrape injuries epithelialized by 3 days following surgery. Rates of wound closure in two separate groups (six eyes each) were 25.83 mm2/day (r = 0.96) and 29.56 mm2/day 9r = 0.97). Lamellar keratectomy injuries epithelialized by 7 to 8 days, which is substantially longer than that observed for scrape injuries. Rates of wound healing in two separate untreated groups (8 and 10 eyes) were 10.88 mm2/day (r = 0.95) and 9.00 mm2/day (r = 0.93), respectively, which were not significantly different. Analysis of variance comparing rates of wound closure indicated that lamellar keratectomy injuries heal at a significantly slower rate when compared to scrape injury (p less than 0.0005).(ABSTRACT TRUNCATED AT 250 WORDS)
