Oligoarthritis is the most common type of juvenile idiopathic arthritis (JIA).

  • Oligoarthritis affects about two-thirds of children and young people with arthritis and most commonly affects one or both knees.
  • This form of arthritis is often mild and is the most likely to go away and leave little or no damage to your joints.
  • This type of arthritis has the highest chance of you developing chronic anterior uveitis (inflammation of the eye), so you’ll need regular eye checks with an ophthalmologist (eye specialist). This eye inflammation doesn’t cause a red or painful eye but still can cause reduced vision if it isn’t treated. This is why regular checks are important.
