Effect of oral supplements of CFW on the detachment of corneal epithelium in PM_2.5-induced DED rats. (A) Representative images of H&E-stained images of corneal sections (n = 4). Black arrows indicate the detached and swollen epithelium. Scale bar, 50 μm. (B) The numbers of the detached corneal epithelium of 100 μm² in five different sections were counted. The data are expressed as the means ± standard deviation (n = 10). * p < 0.05 and *** p < 0.001 compared to the control group. # p < 0.05 and ### p < 0.001 compared to the PM_2.5-induced DED group.
