Retinal Vein Occlusion

What is Retinal Vein Occlusion

RVO occurs when a blockage in the retinal vein causes blood to leak into the retina, leading to swelling and damage. This can cause vision problems and even blindness if left untreated.

Causes and Risk Factors

RVO is associated with:

• High blood pressure
• High cholesterol
• Diabetes
• Glaucoma
• Age (more common in people over 50)

Indications and Symptoms

Symptoms of RVO may include:

• Sudden vision loss or blurriness
• Distorted vision
• Blind spots
• Floaters (dark spots)

Screening and Timing

If you experience sudden vision changes, see an eye doctor immediately. A comprehensive eye exam will include:

• Visual acuity test
• Dilated eye exam (where your pupils are widened with eye drops)
• Retinal imaging (photographs of the retina)

Treatment Option

Treatment for RVO aims to reduce swelling, prevent further vision loss, and improve vision. Options include:

• Anti-vascular endothelial growth factor (anti-VEGF) injections: Medications that help reduce swelling.
• Steroid injections: Medications that reduce inflammation.
• Laser treatment: To reduce swelling and prevent further vision loss.

Good News

With prompt treatment, many people with RVO can regain some vision and prevent further vision loss. Regular follow - ups with your eye doctor are crucial to monitor the condition.

What Can You do?

• Manage your blood pressure, cholesterol, and diabetes
• Schedule regular eye exams
• Report any vision changes to your doctor promptly

By staying proactive and working with your healthcare team, you can protect your vision and reduce the
risk of complications.
