Do you know the risk factors for glaucoma? Find out.

Acute angle closure glaucoma of the right eye . Note the mid sized pupil on the left that was not reactive to light and conjunctivitis.


Glaucoma is a group of diseases that can damage the eye's optic nerve and result in vision loss and blindness. While glaucoma can strike anyone, the risk is much greater for people over 60, according to information from the National Institute of Health's National Eye Institute.

There are several different types of glaucoma. Most of these involve the drainage system within the eye. At the front of the eye there is a small space called the anterior chamber. A clear fluid flows through this chamber and bathes and nourishes the nearby tissues.

In glaucoma, for still unknown reasons, the fluid drains too slowly out of the eye. As the fluid builds up, the pressure inside the eye rises. Unless this pressure is controlled, it may cause damage to the optic nerve and other parts of the eye and result in loss of vision.

Your Medicare Part B plan covers a glaucoma test once every 12 months for people at high risk for glaucoma. You’re at high risk if you have diabetes, a family history of glaucoma, are African American and 50 or older, or are Hispanic American and 65 or older. The screening must be done or supervised by an eye doctor who’s legally allowed to do this test in Missouri.

You pay 20% of the Medicare-approved amount, and the Part B deductible applies. In a hospital outpatient setting, you also pay a copayment.
