Fig 5. Representative pictures of HE staining of corneas from each of the five groups.

Fig 5

(a) Normal corneas (control): three to five epithelial layers can be observed. Damage to the epithelium was observed in (b) dry-eye syndrome (DES; 0.1% BAC) and (c) phosphate-buffered saline (PBS)-treated group: the layered structured was destroyed and sponge-like stroma were found; (d) serum eye drops (SEDs) and (e) solvent/detergent-treated (S/D)-SEDs were similar to control groups with multilayered epithelium in the apical part.
