Glaucoma Disease


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.

At first, glaucoma doesn’t usually have any symptoms. That’s why half
of people with glaucoma don’t even know they have it.

Over time, you may slowly lose vision, usually starting with your side
(peripheral) vision – especially the part of your vision that’s closest to your
nose. Because it happens so slowly, many people can’t tell that their vision is
changing at first.

But as the disease gets worse, you may start to notice that you can’t
see things off to the side anymore. Without treatment, glaucoma can
eventually cause blindness.

Risk factors1

Anyone can get glaucoma, but some people are at higher risk. You’re at
higher risk if you:

  • Are over age 60, especially if you’re Hispanic/Latino
  • Are African American and over age 40
  • Have a family history of glaucoma
  • Talk with your doctor about your risk for glaucoma and ask how often
    you need to get checked. If you’re at higher risk, you need to get a
    comprehensive dilated eye exam every 1 to 2 years
