Central retinal vein occlusion (CRVO) is a condition in which the central retinal vein, which carries blood away from the retina, becomes blocked. This blockage can cause swelling of the retina, decreased vision, and other vision problems. It is the most common cause of vision loss in people over the age of 50. Treatment for CRVO may include medications, laser treatments, or surgery.

The most common symptom of central retinal vein occlusion is sudden, painless Vision loss in one eye. Other symptoms may include:

- Blurred vision

- Dark spots in the vision

- Floaters

- Redness in the eye

- Increased sensitivity to light

- Swelling of the retina

- Headache

- Eye pain

The exact cause of central retinal vein occlusion (CRVO) is unknown, but it is believed to be caused by a combination of factors, including:

- High blood pressure

- Diabetes

- High cholesterol

- Atherosclerosis (hardening of the arteries)

- Blood clotting disorders

- Eye trauma

- Inflammation of the blood vessels in the eye

- Genetic predisposition

- Smoking

- Age (CRVO is more common in people over the age of 50)

1. Laser therapy: This is the most common treatment for central retinal vein occlusion. It involves using a laser to reduce the amount of fluid in the eye and improve vision.

2. Intravitreal injections: These injections are used to reduce swelling and improve vision. They can also be used to reduce the risk of further vision loss.

3. Vitrectomy: This is a surgical procedure that removes the vitreous gel from the eye. It can help reduce swelling and improve vision.

4. Anti-VEGF therapy: This is a type of medication that is injected into the eye to reduce swelling and improve vision.

5. Corticosteroids: These medications can be used to reduce inflammation and improve vision.

1. Age: Central retinal vein occlusion is more common in people over the age of 50.

2. Hypertension: High blood pressure is a major risk factor for central retinal vein occlusion.

3. Diabetes: People with diabetes are at an increased risk of developing central retinal vein occlusion.

4. High cholesterol: High cholesterol levels can increase the risk of central retinal vein occlusion.

5. Smoking: Smoking increases the risk of developing central retinal vein occlusion.

6. Glaucoma: People with glaucoma are at an increased risk of developing central retinal vein occlusion.

7. Cardiovascular disease: People with cardiovascular disease are at an increased risk of developing central retinal vein occlusion.
