Central Retinal Vein Occlusion (CRVO): Your Guide

At a Glance

Central retinal vein occlusion (CRVO), often called an eye stroke, causes sudden vision loss but is highly treatable. Management typically involves specialized eye injections to protect your vision, alongside cardiovascular evaluations to address any underlying health risks.

Receiving a diagnosis of Central Retinal Vein Occlusion (CRVO) is frightening. Whether you’ve just experienced sudden vision loss or are reeling from hearing the words “eye stroke,” you likely have many questions about what this means for your future.

Common questions in this guide

What is Central Retinal Vein Occlusion (CRVO)?
CRVO, sometimes called an eye stroke, is a serious condition that causes sudden vision loss. It occurs when the main vein carrying blood away from the retina becomes blocked, but modern medicine offers highly effective ways to manage it.
What are the main treatments for CRVO?
The gold standard treatment for managing CRVO symptoms and protecting your vision involves specialized eye injections. Your eye doctor will create a specific, long-term treatment plan based on your eye scans and the severity of your condition.
Should I see a cardiologist or primary care doctor after a CRVO diagnosis?
Yes, because CRVO is closely linked to overall cardiovascular health, it is highly recommended to follow up with a primary care doctor or cardiologist. They can evaluate and manage underlying health conditions that may have contributed to the eye stroke.
Is it safe to continue driving and exercising with CRVO?
You should ask your eye doctor if your current daily activities are safe to continue. Depending on the severity of your sudden vision loss and your specific subtype of CRVO, you may need to temporarily modify activities like driving.
How do doctors monitor CRVO over time?
Your doctor will use specialized, painless eye scans, such as OCT (Optical Coherence Tomography) and FA (Fluorescein Angiography). These scans map your eye health and help your care team monitor changes to your vision over the long term.
