Abstract: It is intended to provide an animal model which shows a naturally occurring eye disease symptom, particularly ocular hypertension and/or retinal degeneration. The invention relates to a non-human animal for eye disease model in which the function of Vav2 gene and/or Vav3 gene have/has been impaired. Because the animal shows a naturally occurring eye disease symptom, such as ocular hypertension and/or retinal degeneration without administering a drug or placing it in a special growth environment, it can be used as a model useful for elucidation of onset mechanism of eye disease or evaluation for therapeutic agent for eye disease. When it is applied for such a purpose, because it is not affected by an exogenous factor, which is conventionally administered for artificially inducing eye disease, it reflects a natural pathology, therefore, the clinical and industrial usefulness thereof is high.
