About Birdshot chorioretinopathy

What is Birdshot chorioretinopathy?

Birdshot chorioretinopathy (BCR) is a rare, chronic, inflammatory eye disease that affects the retina and choroid. It is characterized by multiple, small, white lesions in the retina and choroid, which can lead to vision loss. It is most commonly seen in people of Northern European descent, and is usually diagnosed in people between the ages of 30 and 50. Treatment typically involves immunosuppressive medications, laser therapy, and/or surgery.

What are the symptoms of Birdshot chorioretinopathy?

The most common symptoms of Birdshot chorioretinopathy include:

-Decreased vision

-Blurred vision

-Night blindness

-Sensitivity to light


-Flashes of light

-Distorted vision

-Reduced color vision

-Central or peripheral vision loss

-Eye pain


-Eye fatigue

-Double vision

-Eye redness

What are the causes of Birdshot chorioretinopathy?

Birdshot chorioretinopathy is an autoimmune disorder of the eye, meaning that it is caused by the body's own immune system attacking healthy tissue. The exact cause of Birdshot chorioretinopathy is unknown, but it is believed to be triggered by a combination of genetic and environmental factors. Genetic factors may include mutations in certain genes, such as the HLA-A29 gene, which is associated with the disorder. Environmental factors may include exposure to certain viruses, such as the Epstein-Barr virus, or to certain medications.

What are the treatments for Birdshot chorioretinopathy?

The main treatment for Birdshot chorioretinopathy is immunosuppressive therapy, which is used to reduce inflammation and prevent further damage to the retina. This may include medications such as corticosteroids, methotrexate, cyclosporine, and mycophenolate mofetil. In some cases, photodynamic therapy (PDT) may be used to reduce inflammation and improve vision. In severe cases, a vitrectomy may be necessary to remove scar tissue and improve vision.

What are the risk factors for Birdshot chorioretinopathy?

1. Age: Birdshot chorioretinopathy is most commonly seen in individuals between the ages of 40 and 60.

2. Gender: Birdshot chorioretinopathy is more common in women than in men.

3. Ethnicity: Birdshot chorioretinopathy is more common in individuals of Northern European descent.

4. Genetics: Birdshot chorioretinopathy is associated with certain HLA (human leukocyte antigen) gene types.

5. Autoimmune diseases: Individuals with certain autoimmune diseases, such as rheumatoid arthritis, are at an increased risk of developing Birdshot chorioretinopathy.

Is there a cure/medications for Birdshot chorioretinopathy?

Yes, there are treatments available for Birdshot chorioretinopathy. These include medications such as corticosteroids, immunosuppressants, and biologic agents. Laser photocoagulation and photodynamic therapy may also be used to treat the condition. In some cases, surgery may be necessary.
