In about half of all cases, the specific cause of uveitis isn't clear. If a cause can be determined, it may be one of the following:

  • Eye injury or surgery
  • An autoimmune disorder, such as sarcoidosis or ankylosing spondylitis
  • An inflammatory disorder, such as Crohn's disease or ulcerative colitis
  • An infection, such as cat-scratch disease, herpes zoster, syphilis, toxoplasmosis, tuberculosis, Lyme disease or West Nile virus
  • A cancer that affects the eye, such as lymphoma
