Symptoms of Glaucoma

Glaucoma makes it hard to see objects to the side and out of the corner of the eye. A person may feel as though they are looking through a tunnel. Eyesight can worsen until a person becomes blind.

People with open-angle glaucoma often do not have symptoms at first. Vision problems happen as it gets worse. People with angle-closure glaucoma may have some early problems that lead up to an attack.

Glaucoma may cause:

  • Blind spots
  • Blurred eyesight
  • Halos around lights
  • Eye aching or stinging
  • Problems seeing in dim light
  • Problems focusing on close work
  • Problems seeing objects to the side and out of the corner of the eye
  • Tunnel vision

People with angle-closure glaucoma may have these more severe problems that need care right away:

  • Eye pain
  • Facial pain
  • Blurred or cloudy eyesight
  • Redness and swelling of the eye
  • Pupil(s) that do not react to light
  • Swollen eyelids
  • Tearing
  • Nausea or vomiting
