Glaucoma is an eye condition that can result in too much pressure from eye fluid in the eye. This high pressure can damage the optic nerve and if the pressure persists, glaucoma will worsen your sight. When left untreated, glaucoma can cause loss of sight in just a few years. Glaucoma NZ reports that 10% of people over 70 will have Glaucoma.

Are you at risk?

You are at an increased risk of glaucoma if you:

  • Are older than 40
  • Have a family history of glaucoma
  • Have near-sightedness (myopia)
  • Have diabetes
  • Have high blood pressure
  • Have a history of migraine
  • Use cortisone or steroids
  • Have a previous eye injury


What are the symptoms of Glaucoma?

Usually there are no symptoms except vision loss. In a few cases glaucoma will develop rapidly with:

  • Blurred Vision
  • Loss of side vision
  • Seeing coloured halos around lights
  • Redness of the eye
  • Nausea or vomiting
  • Pain in the eye.


Glaucoma cannot be prevented, but it can be detected and treated before vision loss occurs. If detected and treated early, the disease can be controlled. Get your eyes examined regularly.
