What Is Autoimmune Uveitis?

Autoimmune uveitis is inflammation inside the eye caused by the body's immune system attacking its own tissues. The uvea includes the iris, ciliary body, and choroid, which supply blood to the retina. The condition can affect one or both eyes and lead to redness, pain, and vision changes. It can be chronic and recurrent if not properly controlled.

What Causes Autoimmune Uveitis?

It occurs when immune cells mistakenly target eye antigens, sometimes linked with systemic diseases such as ankylosing spondylitis, sarcoidosis, or Beh?et's disease. Genetic predisposition and environmental triggers play a role. The resulting inflammation damages delicate ocular tissues. Identifying underlying disorders helps guide treatment.

How Autoimmune Inflammation Starts

The immune system confuses normal ocular proteins for foreign material and launches an inflammatory cascade. This process increases vessel permeability, allowing fluid and immune cells to infiltrate sensitive ocular layers.

When to See Your Doctor

You should see your eye doctor if you notice sudden or persistent changes in your vision such as blurriness, flashes of light, floaters, or eye pain. Redness, swelling, or discharge that does not improve with basic care also warrants a checkup. Even if symptoms seem mild, getting a professional evaluation can help detect problems early and prevent complications. Regular eye exams are also important to monitor your overall eye health and keep your vision clear.

How Is Autoimmune Uveitis Treated?

Treatment often begins with corticosteroid drops, injections, or oral therapy to reduce inflammation. Long term control may involve immunosuppressive or biologic agents under specialist care. Regular monitoring is necessary to balance inflammation control with medication side effects. Early intervention protects sight.

What Are the Symptoms?

Patients typically report pain, redness, blurred vision, and sensitivity to light. Floaters can appear during inflammation. Symptoms fluctuate depending on the disease pattern. Immediate medical attention prevents complications like cataracts or glaucoma.

Can It Be Cured?

Autoimmune uveitis is usually managed rather than cured. Some cases go into remission for years. Ongoing follow up and adherence to medication keep inflammation quiet. Coordinated care between eye specialists and rheumatologists improves outcomes.

FAQs: Autoimmune Uveitis

Is it contagious? No, it's not an infection.

Can stress trigger flares? Stress alone doesn't cause it but can worsen autoimmune activity.

Will I lose vision? Early, consistent care usually preserves vision.
