Glaucoma is associated with several risk factors including
high eye pressure2

  • African American or Hispanic ancestry
  • Age greater than 603,8 years
  • Glaucoma in other family members
  • Near or farsightedness
  • Long-term steroid treatment
  • Diabetes
  • Eye injury or trauma
  • High blood pressure
  • High eye pressure—
    an important, treatable glaucoma risk factor1

If you have any risk factors for glaucoma, you should have your eyes checked regularly by your doctor.

Unfortunately, open-angle glaucoma does not have any early warning signs.

  • You cannot feel high eye pressure
  • By the time you notice a change in your vision, the damage may have already occurred

Regular appointments with your eye doctor are the only way to detect glaucoma early.


  • When the fluid inside the eye cannot drain properly, it backs up like a clogged drain and increases eye pressure9
  • High eye pressure may damage the optic nerve3
  • A damaged optic nerve can lead to loss of peripheral vision3
  • Eventually, vision loss may progress to the point of blindness9

Vision loss due to glaucoma often starts with the peripheral vision.3

Many people with glaucoma don’t realize it because they don’t actually see dark areas—they have a narrower field of vision, which means they see less of their surroundings.9 Not all glaucoma patients experience vision loss the same way. Vision loss may differ depending on the severity of damage and its location.

Peripheral vision loss due to glaucoma may result in “tunnel vision.”3

It’s important to have your eyes checked. If you have high eye pressure, it is essential to take your medication as prescribed by your doctor.

Although glaucoma cannot be cured, National Eye Institute clinical studies have shown that lowering high eye pressure can reduce the risk of glaucoma-related vision loss.6,10,11
