Figure 7
Representative picture for each group: (A) 1w O/O, the corneal tissue is structurally intact. (B) 1w A/O, the structure of corneal epithelial cells is relatively intact, with no separation observed between the corneal epithelium and stroma. (C) 2w O/O, for the separation of the corneal epithelium from the corneal stroma, there is visible separation between the epithelial cell layers or the focal epithelial defects. (D) 2w A/O, the structure and morphology of the corneal epithelium can no longer be clearly observed, with the integrity of the corneal epithelium found to be disrupted.
