Cancer-associated retinopathy (CAR) is a rare, vision-threatening condition that is caused by an autoimmune response to certain types of cancer. It is characterized by the development of retinal lesions, which can lead to vision loss. CAR is most commonly associated with small cell lung cancer, but can also be seen in other types of cancer, such as breast, ovarian, and prostate cancer. Treatment typically involves immunosuppressive medications, such as corticosteroids, to reduce inflammation and prevent further damage to the retina.

The most common symptom of cancer-associated retinopathy is decreased vision. Other symptoms may include:

-Blurred vision

-Flashing lights

-Floaters
-Distorted vision
-Reduced color vision
-Night blindness
-Sensitivity to light
-Loss of peripheral vision

Cancer-associated retinopathy (CAR) is a rare, progressive eye disorder caused by an autoimmune response to certain types of cancer. It is believed to be caused by an immune system reaction to cancer cells, which can cause inflammation and damage to the retina. The exact cause of CAR is unknown, but it is thought to be related to the body’s immune system attacking the cancer cells. Other possible causes include radiation therapy, chemotherapy, and certain medications used to treat cancer.

1. Laser photocoagulation: This is a procedure that uses a laser to seal off the abnormal blood vessels in the retina.

2. Intravitreal injections: This is a procedure that involves injecting medications directly into the eye to reduce inflammation and block the growth of abnormal blood vessels.

3. Photodynamic therapy: This is a procedure that uses a light-activated drug to destroy abnormal blood vessels in the retina.

4. Anti-VEGF therapy: This is a type of medication that blocks the growth of abnormal blood vessels in the retina.

5. Corticosteroid injections: This is a type of medication that can reduce inflammation and block the growth of abnormal blood vessels in the retina.

6. Surgery: In some cases, surgery may be necessary to remove abnormal blood vessels in the retina.

1. Advanced age

3. Long-term use of certain immunosuppressive drugs, such as cyclosporine
4. Long-term use of certain hormones, such as tamoxifen
5. Long-term use of certain antibiotics, such as chloramphenicol
6. Long-term use of certain antifungal drugs, such as ketoconazole
7. Long-term use of certain antiviral drugs, such as ganciclovir
8. Long-term use of certain antineoplastic drugs, such as interferon

Yes, there are treatments available for cancer-associated retinopathy. These include laser photocoagulation, intravitreal injections of anti-VEGF agents, and intravitreal injections of corticosteroids. Additionally, some patients may benefit from oral medications such as acetazolamide, hydroxychloroquine, and bevacizumab.
