Juvenile Idiopathic Arthritis - What Happens

Complications

Complications associated with JIA can include:

  • Inflammatory eye disease, such as uveitis. Children and adults with this condition can develop cataracts, glaucoma, corneal degeneration (band keratopathy), or vision loss.
  • Growth abnormalities. These include unequal leg lengths, an imbalance in growth of the jaw, and temporary delay in breast growth.
  • Joint damage. This is common in the polyarticular form of JIA and can occur early. About 30 to 50 out of 100 children with JIA may have some level of disability that continues into adulthood.2 Long-term problems can be mild and have little effect on daily activities.

Some children with polyarthritis get arthritis in the neck that can cause the neck bones to fuse together.

Complications of systemic JIA include heart or lung problems, such as pericarditis, pleuritis, or pericardial effusion. A rare lung complication is the formation of scar tissue in the lungs (pulmonary fibrosis).
