What is glaucoma?
Glaucoma is the leading cause of blindness in the United States, especially for older people.  It is a disease of the optic nerve caused by too much pressure inside the eye.  The pressure is caused by clogged drainage ports inside the eye, generally as a result of the aging process.

Will I know it when I get glaucoma?
No. Glaucoma is a disease which is oftentimes referred to as "The sneak thief of sight". Because it has no apparent symptoms, it will gradually rob people of their vision without them being aware of it. That's why it's important that all people over the age of 45 be absolutely certain to have themselves tested for glaucoma at least once each year.

Does glaucoma ever go away?
No. This is a lifelong disease that requires constant monitoring by an eye doctor.

Does glaucoma medication help improve my vision?
No. Glaucoma medication helps control the glaucoma so it doesn’t get worse, but it will have no effect on your vision.

What happens if my glaucoma medication doesn't succeed in controlling my glaucoma?
There are two other alternatives: lasers and surgery. Your eye doctor will recommend to you when he believes it's appropriate to do these.
