Provided is a pterygium animal model produced by injecting human-derived pterygial epithelial cells that are isolated and cultured in vitro. The animal model has characteristics similar to those of pterygium, which are observed only in humans, wherein such characteristics are caused in such a way that pterygial epithelial cells are isolated from human pterygium corneal tissues and cultured, the cultured pterygial epithelial cells are sub-cultured, and human-derived pterygial epithelial cells of which identify is confirmed are injected into the nasal subconjunctival space of mice. The pterygium animal model allows a pterygium therapeutic agent to be effectively screened.
