What is Glaucoma?
Glaucoma is a group of eye diseases that can cause vision loss and blindness by damaging a nerve in the back of your eye called the optic nerve.  
The symptoms can start so slowly that you may not notice them. The only way to find out if you have glaucoma is to get a comprehensive dilated eye exam.  

There’s no cure for glaucoma, but early treatment can often stop the damage and protect your vision.
