Can glaucoma make me go blind?

Possibly: Glaucoma mostly, if detected, is treatable. Some lose vision but blindness is uncommon unless neglected or undetected until too late. Certainly it is a cause of blindness, especially in the third world.

It's possible: Glaucoma is a very serious eye condition that can lead to blindness in it's late stages. It's known as the sneak thief of sight because it typically does not have symptoms in the early stages. The best way to prevent blindness is to keep up with eye examinations and to follow the doctor's recommendations for treatment. If ever in doubt seek a second opinion.

Yes it can: Best approach is early detection and prompt treatment to preserve vision and decrease potentially blinding consequences of glaucoma. If you're of African American, Asian or Hispanic descent, positive family history of glaucoma, over 40-50, eye injury, highly nearsighted, using prednisone, or are concerned, then get an eye examination by an ophthalmologist.
