Millions of Americans have
primary open-angle glaucoma (POAG)

Did you know that, if you have primary open-angle glaucoma, you're far from alone. It's true. In fact, it's the most common type of glaucoma in the U.S. One percent of Americans have POAG – that's over 3,000,000 people – and most of them are in the over-50 group.

What causes
primary open-angle glaucoma?

POAG is thought to develop when the eye's drainage system becomes inefficient over time. This leads to an increased amount of fluid and a gradual buildup of pressure within the eye. The buildup of pressure slowly destroys your optic nerve, leading to vision loss.

POAG comes without warning

There is no pain or swelling. In fact, by the time you notice you're having problems seeing and are displaying glaucoma symptoms, damage has already been done, and is permanent.

The stages of sight loss

POAG takes away your sight gradually, in stages.
1. First you may find that you miss objects to the side and out of the corner of your eye.
2. Then, if left untreated, you may discover you suddenly have no side or peripheral vision. Essentially, it looks like you're always peering down a long tunnel.
3. Over time, your remaining vision decreases until there's nothing left. But that doesn't have to happen to you if you seek out testing and treatment.
