Uveitis has many different causes:

  • A virus, such as shingles, mumps or herpes simplex
  • A fungus, such as histoplasmosis
  • A parasite, such as toxoplasmosis
  • Related disease in other parts of the body, such as arthritis, gastrointestinal disease or collagen vascular disease such as lupus
  • A result of injury to the eye

If you smoke, stop. Studies have shown that smoking contributes to the likelihood of developing uveitis.
