What Is Autoimmune Retinopathy?

What Causes Autoimmune Retinopathy?

Circulating anti retinal antibodies emerge spontaneously or in association with tumors that share retinal antigens. Genetic predisposition and immune dysregulation play roles. Over time, antibodies and immune cells damage photoreceptors and bipolar cells. Systemic evaluation screens for underlying malignancy.

How Autoantibodies Affect the Retina

Antibodies bind to proteins in retinal cells and trigger inflammation that disrupts the outer retinal layers. The progressive damage reduces light detection, leading to gradual loss of peripheral or central vision.

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 Retinopathy Treated?

Immunosuppressive therapy such as corticosteroids, IVIG, rituximab, or other agents is used to dampen antibody activity. Treating an associated cancer is critical in paraneoplastic cases. Visual rehabilitation and tinted lenses help symptoms. Close follow up assesses response and adjusts therapy.

How Is It Diagnosed?

Diagnosis relies on a combination of symptoms, electroretinography showing reduced photoreceptor function, and the presence of anti retinal antibodies. OCT may reveal outer retinal loss as disease advances. Imaging and labs rule out mimics like inherited dystrophies. A multidisciplinary team coordinates care.
