Glaucoma Management
"The Sneak Thief of Sight"
Glaucoma is a family of diseases that affects pressure within the eye, damaging the optic nerve. When pressure inside the eye increases, blind spots in peripheral areas of vision may occur. Of all conditions and diseases of the eye, glaucoma is one of the leading causes of blindness in the United States.
Often called the "silent thief" of sight, most forms of glaucoma do not produce symptoms until vision is already severely damaged. But if diagnosed early, the disease can be controlled and permanent vision loss can be prevented.
There several different types of glaucoma including:
- Open angle. Your eye can't process fluid properly, so pressure within the eye builds and strangles the optic nerve.
- Angle closure or pigmentary. The iris of the eye bulges and blocks drainage. This can happen suddenly, which is a medical emergency. Or it can develop slowly.
- Normal tension. Your eye pressure remains normal, but your optic nerve is damaged. Researchers don't know why this happens.
- Early onset. Babies can be born with glaucoma, and some kids develop it with the first few years.
Most types of glaucoma cause peripheral vision loss. You can see well in the center, but the edges of vision begin to fade away. Over time, it can even affect central vision and result in total blindness.
What are the risk factors for glaucoma?
Certain characteristics warrant more frequent testing for glaucoma
The following factors put you at a higher risk to be diagnosed with glaucoma:
• Age: If you’re 65 years old or older, you’re at a higher risk to develop glaucoma.
• Family history: If someone in your family has glaucoma, you’re at a higher risk to develop glaucoma.
• Race: If you’re African-American, you’re four times more likely to develop glaucoma.
• Health: If you have diabetes, you’re more likely to develop glaucoma.
• Eyesight: If you’re nearsighted, you’re more likely to develop glaucoma.
• Corneal thickness: If your corneal thickness is thinner than normal, you’re more likely to develop glaucoma.
Does Medicare Cover Glaucoma Tests?
For those with active glaucoma Medicare covers medical visits and related testing. Medicare Part B may pay for part of an annual glaucoma tests for patients who are considered to be high risk for developing glaucoma.

Treatment for Glaucoma
The number of people losing all vision due to glaucoma is dropping.
Doctors are catching glaucoma earlier, and they're using innovative therapies to preserve vision. In one Mayo Clinic study, they say, blindness probability dropped about 50 percent in a 45-year timespan.
Your doctor might use:
- Eyedrops or pills reduce fluid production or help fluid drain the right way. Eyedrops are the most common form of glaucoma treatment.
- Laser surgery. Your doctor uses a laser to create an escape path to help your eye drain better or to create different drainage pathways.
- Conventional surgery. Your doctor uses a scalpel to create a drainage network. This surgery is typically performed as a last resort when nothing else worked.
As with many other eye problems, glaucoma can be detected during a comprehensive dilated eye exam. Your exam will include a visual field test, which can help your doctor see if you're starting to lose peripheral vision, and your internal eye pressure will be measured as well.
Once vision is lost, it cannot be restored. Discovering optic nerve damage and vision loss early, through a comprehensive dilated medical exam, is crucial.
