Corneal epithelial wound healing in rats.

<p>Rats underwent corneal epithelial debridement and topical applicaton of liquid or redissolved powder forms of blood derivatives. Corneal epithelial defects were stained with fluorescein and photographed at 0, 12, 24 and 48 hours to determine wound healing ratios. Compared to the control (no topical treatment), rats treated with blood derivatives had greater wound healing ratios at 24 hours. Effects were similar for liquid and redissolved powder forms. All rats had fully healed corneal epithelium at 48 hours. *p<0.05 compared to the control. **p<0.01 compared to the control. Error bars indicate SD.
