Representative immunohistochemistry image showing collagen type IV staining of blood vessels (red staining) in tissue sections of rabbit corneas collected 14 days after sterile water (A) or enalapril treatment (B). The images show angiogenesis in the central cornea region. Enalapril-treated corneas showed fewer blood vessels. Nuclei are stained blue with DAPI. The scale bar denotes 100 µm.
