What causes a retinal vein occlusion?

Retinal vein occlusion occurs when a vein in the retina becomes blocked, often due to a blood clot. Risk factors include high blood pressure, diabetes, high cholesterol, and other vascular conditions that affect blood flow.

Can vision improve after a retinal vein occlusion?

Vision may improve in some cases, especially with timely treatment. While some patients regain partial vision, outcomes vary depending on the severity and how quickly care is received.

Is retinal vein occlusion permanent?

The blockage itself is typically permanent, but its effects can often be managed with treatment. Early intervention can help reduce complications and preserve vision.

What complications can occur if retinal vein occlusion is not treated?

Untreated retinal vein occlusion can lead to complications such as macular edema, retinal ischemia, and abnormal blood vessel growth, which may result in significant or permanent vision loss.

Retinal Vein Occlusion (BRVO, CRVO)

Advanced care to reduce swelling, restore blood flow, and preserve visual function

What Is Retinal Vein Occlusion?

A retinal vein occlusion occurs when one of the veins that drains blood from the retina becomes blocked. This causes blood and fluid to leak into the retinal tissue, which can lead to swelling and blurred vision.

Who it affects:

This condition can occur at any age but is more common in people with vascular risk factors like high blood pressure, diabetes, glaucoma, or high cholesterol.

Types of Retinal Vein Occlusion

Central retinal vein occlusion (CRVO)

Blockage of the main vein can lead to more severe vision loss and complications

Branch retinal vein occlusion (BRVO)

Blockage of a smaller tributary can have milder symptoms or no symptoms

Common Symptoms

Sudden or painless blurring of vision in one eye

Vision distortion or decreased vision

Possible dark spots or floaters in vision

Vision may worsen over days to weeks after the blockage

Warning Signs:

Call us right away if you experience sudden vision changes, blurred vision, new floaters, or a sudden dark spot, as these symptoms may indicate a serious retinal condition requiring immediate medical attention.

Dr. Wong is very nice, efficient and thorough. She explained everything to me as she was doing the exam. Went over findings. Made recommendations and a plan of action. It is great that there is free parking. Her office is very nice and spacious. For my first time ever visiting an ophthalmologist, this was a very good experience. I highly recommend her.
