MEDFORD, Ore. -- Glaucoma is a disease that damages the optic nerve, which is the main nerve in your eye.
It doesn't cause symptoms at first, but it affects the edges of what you see when it starts to cause vision loss. However, you can still see things through the center.
Doctors check for glaucoma by checking your vison and check the pressure of your eye by blowing air into your eye with a special tool.
It can be treated with eye drops, laser therapy, or even surgery.
