Retinal Diseases

Retinal Vein Occlusion

A retinal vein occlusion is when a vein in your retina is blocked (occluded). This can be caused by a blood clot, or it can happen when a larger blood vessel presses down on the vein.

When a retinal vein is blocked, blood and fluid can build up in the retina. This may cause swelling, bleeding, blurry vision, floaters, or vision loss.

Retinal Vascular Disease

Sudden blurry vision or new floaters should be evaluated promptly.

Retinal vein occlusion can affect central vision, especially when swelling develops in the macula.

Call an ophthalmologist right away if symptoms occur.

It is very important to call an ophthalmologist right away if you have blurry or decreased vision, many new floaters, or pain inside the eye.

Normal Retina vs. Retinal Vein Occlusion

Retinal vein occlusion may cause retinal hemorrhages, dilated or tortuous veins, swelling, and areas of poor blood flow in the retina.

About RVO

What Is Retinal Vein Occlusion?

A retinal vein occlusion occurs when one of the veins carrying blood away from the retina becomes blocked. This blockage can cause blood and fluid to leak into the retina.

If fluid collects in the macula, the part of the retina responsible for sharp central vision, patients may notice blurry or distorted vision.

Types

Branch vs. Central Retinal Vein Occlusion

A branch retinal vein occlusion affects one smaller branch of a retinal vein. A central retinal vein occlusion affects the main retinal vein and may involve a larger area of the retina.

The type and severity of the occlusion help guide monitoring and treatment recommendations.

Symptoms

Retinal Vein Occlusion Symptoms

It is very important to call an ophthalmologist right away if you have any symptoms such as:

Blurry or less vision
Noticing a lot of floaters in your field of vision
Pain inside your eye
Sudden change in vision in one eye
Distorted or hazy central vision
Vision loss that may be mild or severe

Causes

Retinal Vein Occlusion Causes

It is not known exactly what causes retinal vein occlusion. However, you are more likely to have retinal vein occlusion if you have:

Diabetes
Glaucoma, or increased pressure inside the eye
High blood pressure
Diseases related to blood vessels, or vascular disease
A history of retinal vascular disease
Other health conditions that affect circulation

Macular Swelling

How RVO Can Affect Vision

Retinal vein occlusion can cause swelling in the macula, called macular edema. When the macula is swollen, central vision may become blurry, distorted, or reduced.

Health Management

Why Overall Health Matters

Diabetes, glaucoma, high blood pressure, or other health problems can lead to retinal vein occlusion. Taking care of your health can help lower your risk of this serious eye problem.

Treatment

Retinal Vein Occlusion Treatments

Your ophthalmologist will treat you based on what he or she sees in your eye. Treatment may include:

Medicine: A drug is given by injections, or shots, inside the eye. It helps to reduce swelling of the macula and slow vision loss.
Laser surgery: Your ophthalmologist may use a laser to shrink certain blood vessels in your retina. This is so that they will not bleed, and to prevent them from growing back.
Managing your health: Diabetes, glaucoma, high blood pressure, or other health problems can lead to retinal vein occlusion. Taking care of your health can help lower your risk of this serious eye problem.
Monitoring: Follow-up visits may include retinal examination and imaging to watch swelling, bleeding, and blood flow changes.

Retinal Vein Occlusion Evaluation and Treatment

If you notice sudden blurry vision, decreased vision, new floaters, or pain inside the eye, it is important to schedule an eye examination promptly. A retina specialist can determine whether symptoms are related to retinal vein occlusion or another retinal condition.
