What is glaucoma?

Glaucoma is a condition that affects the optic nerve of the eye. When damage to the nerve occurs, it blocks visual information to your brain resulting in permanent vision loss. As the damage progresses, the vision loss increases and can continue, if left untreated, until only central vision is left or in some cases, until the person is completely blind.

Am I at risk of developing glaucoma?

The exact causes of glaucoma are unknown. The older you get, the more likely you are to have glaucoma. If you’re over the age of 40 or have a family history of glaucoma, you are most at risk and we recommend you visit your optometrist regularly to have your eyes checked. 

Early detection of glaucoma

Glaucoma cannot be prevented but early detection allows it to be treated to reduce the risk of progression and vision loss. Most people will not even know that they have glaucoma until it is too late, as symptoms don’t appear until permanent damage has occurred.

Fortunately, at Health Partners we are equipped with the latest in technology and have the ability to detect glaucoma before symptoms occur. We do this by working through a series of simple, painless tests, including visual field testing, Intra-ocular pressure (IOP) tests and Optical Coherence Tomography (OCT) to view the optic nerve.

Visual Field testing is a peripheral vision test used to determine an individual’s range of vision – how far around you can see while fixing your eyes on one location. For example, noticing a car pull up next to yours while focussing on the red light in front of you. A decrease in your visual field may indicate the onset of Glaucoma.

IOP tests are designed to measure the pressure of fluid in your eye. An elevated IOP can lead to damage to the optic nerve and a diagnosis of Glaucoma.

OCT uses 3D imaging technology to achieve highly detailed internal imaging of your eye allowing your optometrist to see and measure the delicate structures of your eye and monitor any changes. It’s the ultimate tool for precise diagnosis and treatment. The procedure is safe, there’s no discomfort as there’s no direct contact with your eye and it takes just a few minutes to complete.

Key symptoms of glaucoma

Commonly, glaucoma does not have any obvious symptoms and as a result it is estimated that 50% of glaucoma in Australia remains undiagnosed. Symptoms of glaucoma may include:

  • Blurred vision
  • Seeing coloured rings around lights;
  • Loss of peripheral vision
  • Pain and redness of the eye(s)

Glaucoma can present in a number of different forms (symptoms) and in its earliest stages, you may not experience any symptoms at all so it is important to have a regular eye examination to rule our glaucoma. Any changes to your vision should not be ignored.


Treatment for glaucoma generally consists of prescription eye drops intended to prevent progression of glaucoma and reduce vision loss. In some cases, laser treatment surgery may be required.
