Glaucoma Q & A

How is glaucoma detected?

During an eye exam, Dr. Griessel administers a series of tests to check not only your vision, but also any abnormalities that could be red flags of lingering glaucoma. Depending on your symptoms, she might administer 1 or several glaucoma tests. During a visual field test, for instance, you’ll look straight ahead into a machine that flashes a light at various points in your peripheral vision. Your job is to signal when you see the lights. If you miss any, it could be a warning sign that your peripheral vision is fading — an early warning sign of glaucoma.

The tonometry test — often known as the “puff of air” test — squirts a quick burst of air into your eye. This quick and painless test simply measures your eye pressure to see if you have any abnormalities. In some cases, Dr. Griessel might want to dilate your eyes with drops. Once your pupils are widened, she’ll see your optic nerve and retina, using specialized magnifying lenses.

Are there symptoms of glaucoma?

Usually not at first. Over time, as your peripheral vision starts fading, you’ll feel like you’re always looking through a tunnel. If you don’t seek treatment, that vision also diminishes, leaving you nearly, or completely blind.

What type of surgery is offered for glaucoma?

Laser trabeculoplasty is often the first step in surgical treatment for glaucoma. During this procedure, Dr. Griessel numbs your eye with drops. While holding a special lens next to your eye, the laser aims a high-intensity beam into your eye. These beams make small burns across the meshwork in your eye, allowing extra fluid to drain out.

If for some reason, the laser trabeculoplasty doesn’t work for you, conventional surgery — a trabeculectomy — might be required. This procedure is done in an operating room. While you are awake, you’ll likely be given medication to help you relax and numbing injection around your eye. During the surgery, Dr. Griessel removes a small amount of eye tissue to allow fluid to drain. As a Board Certified ophthalmologist and eye surgery specialist, Dr. Griessel determines the proper surgical treatment for your specific needs.
