Figure 3. Corneal fluorescein staining on the 7th, 10th, and 14th days after chemical cauterization. A: Slit-lamp photograph of corneal fluorescein staining on day 10. The recovery of the corneal epithelium was strongly delayed in the dexamethasone-treated group. B: A statistical comparison of the area of corneal epithelial defect on the 7th, 10th, and 14th days after chemical cauterization. There was a statistically significant difference between the dexamethasone-treated group and the other groups. PBS: PBS, DEX: dexamethasone, AV: Avastin, K-5:KH906 (5 mg/ml), K-10:KH906 (10 mg/ml), K-20:KH906 (20 mg/ml).
