What is Glaucoma?

Glaucoma is a term given to a group of conditions which cause damage to the optic nerve. This nerve carries information from the eye to the brain, where it is perceived as an image. It is usually (but not always) caused by increased pressure in the eye. It is one of the leading causes of blindness for those over the age of 60. Loss of vision can be very gradual, meaning that many of those affected will have no warning signs. 

Can Glaucoma be treated?

Yes, Glaucoma can be treated. The treatment is aimed at slowing down or preventing further nerve damage, however existing damage cannot be reversed.

How is Glaucoma treated?

  • Eye drops to lower the pressure in the eye
  • Laser treatment where a high energy beam is used to increase drainage of fluid from the eye
  • Surgery 

How would I know if I had Glaucoma?

While there are many types of Glaucoma, most people will be unaware they have the condition. For this reason, regular eye exams are advised in order that early signs of the disease can be detected. 

How is Glaucoma diagnosed?

Some of the tests used to detect Glaucoma include:

  • Checking the internal health of the eye to assess for changes in the appearance of the optic nerve
  • Measurement of the pressure within the eye (I.O.P.)
  • Visual field test (central and peripheral vision is assessed)
  • OCT scan where the retinal nerve supply is measured.
  • Repeat scans can be compared with those taken at previous visits, thereby allowing for subtle changes to be detected.
