Glaucoma and Medicare: What You Need to Know About Protecting Your Vision

Did you know that about half of people with glaucoma do not even know they have it?

Glaucoma is often called the “silent thief of sight” because it develops slowly and may not cause noticeable symptoms in the early stages. By the time vision changes become obvious, permanent damage may have already occurred.

Understanding your risk and knowing how Medicare may help cover glaucoma screenings can be an important step in protecting your vision.

What Is Glaucoma?

Glaucoma is not just one disease. It is a group of eye diseases that damage the optic nerve, which is the connection between your eye and your brain.

Glaucoma is often associated with increased pressure inside the eye, but it can also occur when eye pressure is normal. Left untreated, glaucoma can lead to permanent vision loss and even blindness.

Early detection and treatment are important because vision loss from glaucoma cannot be restored.

Why Early Detection Matters

In its early stages, glaucoma usually has no warning signs. There may be no pain, no sudden vision changes, and no obvious symptoms.

The most common type, open-angle glaucoma, typically affects peripheral, or side, vision first. Because central vision can remain clear for a long time, many people do not realize anything is wrong until the disease has progressed.

Other less common forms, such as angle-closure glaucoma, may happen more suddenly and can cause symptoms such as:

• Severe eye pain
• Headache
• Nausea
• Blurred vision
• Seeing halos around lights

These symptoms require immediate medical attention.

How Is Glaucoma Detected?

The only way to know if you have glaucoma is through a comprehensive eye exam. These exams are typically painless and may include tests that check:

• Eye pressure
• Optic nerve health
• Peripheral vision
• The drainage angle of the eye

According to the

National Eye Institute
,
regular eye exams are especially important as we age. Early treatment may include prescription eye drops, laser therapy, or surgery to help prevent further vision loss.

Does Medicare Cover Glaucoma Screenings?

Medicare Part B covers glaucoma screenings once every 12 months for people who are considered high risk.

The screening must be performed or supervised by an eye doctor who is legally allowed to provide the service in your state, such as an ophthalmologist or optometrist.

If you qualify as high risk and receive your screening from a provider who accepts Medicare assignment, Medicare Part B generally covers 80% of the Medicare-approved amount after your Part B deductible has been met. You are typically responsible for the remaining 20% coinsurance.

It is important to confirm that your provider accepts Medicare assignment to help minimize out-of-pocket costs.

What If You Have a Medicare Advantage Plan?

If you have a Medicare Advantage plan, your glaucoma screening coverage may work differently than Original Medicare.

Medicare Advantage plans must cover at least the same medically necessary services as Original Medicare, but provider networks, copays, referrals, and prior authorization rules may vary by plan.

Review your plan details or speak with a Medicare professional to understand how your specific benefits apply.

Who Is at Higher Risk for Glaucoma?

While anyone can develop glaucoma, Medicare considers you at high risk if at least one of the following applies:

• You have diabetes
• You have a family history of glaucoma
• You are African American and age 50 or older
• You are Hispanic and age 65 or older

Because the risk of glaucoma increases with age, regular screenings can be especially important for Medicare beneficiaries.

Protecting Your Vision Starts With a Conversation

If you fall into a high-risk category, talk with your primary care provider or eye doctor about scheduling a glaucoma screening.

Your vision plays a major role in your independence, safety, and overall quality of life. When it comes to your eyesight, waiting for symptoms is not a safe strategy.

A simple, painless screening once a year could help protect your vision for years to come.
