  • What is Juvenile Idiopathic Arthritis Uveitis?

    Nov. 08, 2022

    Juvenile idiopathic arthritis (JIA) is an inflammatory disease of the joints that affects children under the age of 16.

    JIA is an autoimmune disease. In JIA, the body’s healthy joints are attacked by white blood cells (the cells that normally fight disease). This causes inflammation of the joints. It can make walking difficult. Fever and rashes are also common symptoms. JIA is a chronic (ongoing) disease. This means that there is no cure—but there is treatment.

    How does JIA affect the eye?

    Some children with JIA will also get inflammation of the eye. This is called uveitis. Uveitis occurs when the uvea (middle layer of the eyeball that includes the iris or colored part of eye) becomes inflamed. There are different types of uveitis, but JIA mainly affects the front of the uvea (anterior uveitis).

    What are symptoms of uveitis from JIA?

    Symptoms of uveitis include:

    In up to half of patients, there are no obvious symptoms in the beginning. In these children, once symptoms appear, damage to the eye and vision loss may have already happened. This is why all children should see an ophthalmologist right after they are diagnosed with JIA.

    If a child is not diagnosed and treated early, uveitis can cause:

    If your child is diagnosed with juvenile idiopathic arthritis (JIA), they need to see an ophthalmologist as soon as possible.

    How is uveitis from JIA diagnosed?

    Here’s what will happen during the exam:

    Blood tests

    Blood will be tested for antinuclear antibody (ANA). If the test is positive, the child has a greater risk for getting uveitis. Other blood tests may be taken as well.

    Slit-lamp exam

    Your ophthalmologist will use an instrument called a slit lamp to look at your child’s eye. The slit lamp gives the doctor a magnified, detailed view of the eye. He or she can see if there is any damage to the eye from uveitis.

    Based on the results, your ophthalmologist will tell you how often your child needs to come back for an exam.

    Regular eye exams can save your child’s vision

    Uveitis can cause many problems in the eye. If left untreated, these problems can lead to vision loss. The good news is that vision loss from uveitis can be prevented. Early diagnosis and treatment of uveitis can save your child’s vision.

    If your child is diagnosed with JIA, they should see an ophthalmologist right away. They will look for signs of uveitis. After the first exam, your ophthalmologist will tell you when to return for another exam.

    How is uveitis from JIA treated?

    Uveitis is often treated using a team approach. An ophthalmologist will work with your child’s rheumatologist (special doctor that treats autoimmune diseases like arthritis and uveitis) to find the best treatment for him or her.

    Treatment can include:

    Corticosteroids (steroids)

    Steroids are the most common way to treat uveitis. They can be taken orally (pills), in eyedrop form, or by injection.

    Immunosuppressive drugs

    For 7 out of 10 patients, steroids reduce inflammation of the eye. Other patients may need to take immunosuppressive drugs. These are drugs that lower the response of your body’s immune system. This can help control inflammation of the eye and of the joints.
