Central Retinal Vein Occlusion Specialists in Derry & Surrounding Area

Vision loss is something no one wants to think about—after all, the lack of vision means relearning the way you go about your daily life. Central retinal vein occlusion is just one example of an eye condition that can lead to permanent vision loss. It’s important for patients to understand the nature of this condition and who is at the highest risk. Thankfully, the specialists at Derry, NH’s Spindel Eye Associates are here to help you maintain your vision and address conditions that could threaten it. Delve deeper into central retinal vein occlusion and how treatment works.

What Is Central Retinal Vein Occlusion?

Central retinal vein occlusion (CRVO) occurs when the central vein responsible for draining blood from the retina becomes blocked. This blockage leads to increased pressure in the vein, causing blood and fluid to leak into the retina, which can result in swelling and damage to retinal cells. The retina converts light into signals sent to the brain, so any damage to it can significantly impair sight.

Types of CRVO

CRVO comes in two main forms and is categorized based on the severity of the blockage. The team at Spindel Eye Associates can identify which of these forms affect you:

Non-Ischemic CRVO

This type of CRVO is more common and less severe. It involves partial blockage of the retinal vein, leading to milder symptoms. Vision loss is typically moderate, and there is a better chance of recovery with appropriate treatment.

Ischemic CRVO

Ischemic CRVO is rarer but more severe. It involves a complete blockage of the central retinal vein, leading to significant retinal damage and a higher risk of severe vision loss. Patients with this type require more intensive treatment and monitoring.

Recognize the Symptoms of CRVO

Patients with a mild condition may experience very few central retinal vein occlusion symptoms. However, recognizing the early warning signs is crucial for getting effective treatment quickly. Be on the lookout for these symptoms:

Sudden, painless vision loss in one eye
Blurred or distorted vision
Dark spots or floaters in the visual field
Areas of vision loss or blind spots
Pain or redness around the eye (in severe cases)

What Causes Central Retinal Vein Occlusion?

Several factors can contribute to the development of CRVO. If you have any of the following conditions, let us know during your next eye exam:

Atherosclerosis—This hardening and narrowing of the arteries can compress the retinal vein, leading to a blockage.
High Blood Pressure—Hypertension increases the risk of vein occlusion as it may worsen atherosclerosis.
Diabetes—Diabetes can damage blood vessels, making them more susceptible to blockages.
Glaucoma—This eye condition increases intraocular pressure, which can affect blood flow in the retina and contribute to vein occlusion.
Blood Clotting Disorders—Conditions that affect blood clotting can increase the risk of vein blockages in the retina.

How We Diagnose CRVO

CRVO diagnosis typically begins with a comprehensive eye exam. Your provider will take a thorough look at your current eye health and flag any signs of a problem. If central vein occlusion in the retina is detected, you may be asked to undergo further testing, such as imaging or visual acuity exams.

Get the Treatment You Need

While there is no cure for CRVO, several treatments can help manage the condition and improve vision outcomes. Central retinal vein occlusion treatment will depend on the type and severity of your condition but will usually include the following:

Injections

Medications such as anti-VEGF (vascular endothelial growth factor) agents and steroids can be injected directly into the eye to reduce retinal swelling and improve vision.

Laser Therapy

Laser treatments can help reduce the risk of complications and further vision problems. Our specialists will walk you through the procedure and make sure you understand what to expect.

Chronic Condition Management

Controlling conditions like high blood pressure, diabetes, and glaucoma can help reduce the risk of CRVO progression and recurrence. Talk to your primary care doctor or provider at Spindel Eye Associates for ways you can effectively manage your underlying condition.

Are You Affected by These Risk Factors?

Some individuals are at higher risk of developing CRVO. Those with the conditions discussed above (hypertension, diabetes, and blood clotting disorders) should be especially vigilant for CRVO. However, these aren’t the factors increasing your chances of this diagnosis. Patients older than 50, especially those who smoke, should watch for the signs of CRVO and consider making lifestyle changes to minimize their risk.
