From: Extracellular matrix and fibroblast injection produces pterygium-like lesion in rabbits
Comparison of the histopathological criteria evaluated in human pterygium a and the rabbit conjunctival fibrovascular tissue in a right eye b. Fibroconnective tissue (asterisk) is observed with a great amount of blood vessel (open triangle) coated by acanthotic squamous epithelium (filled triangle). In the rabbit tissue, edema interstitial is observed but not in human pterygium (H&E ×100)
