From: Effect of ethanol-treated mid-peripheral epithelium on corneal wound healing in rabbits
The concentration (pg/ml) of VEGF in rabbit tears preoperatively 1 day, 3 days and 5 days after epithelial removal. The differences between groups were statistically significant on post-operative day 1, day 3 and day 5 (p < 0.05, Mann–Whitney U test). * denotes a statistically significant difference between group 1 and group 2 (p < 0.05). ǂ denotes the difference between group 2 and group 3 (p < 0.05). Group 1: 8.0-mm BSS treatment and 8.0-mm epithelial removal, Group 2: 8.0-mm ethanol treatment and 8.0-mm epithelial removal, Group 3: 9.0-mm ethanol treatment and 8.0-mm epithelial removal.
