GLAUCOMA
AWARENESS

Early detection is key

Glaucoma is the leading cause of irreversible blindness world-wide

Glaucoma is often nicknamed the ‘silent thief of sight’ because it has little to no obvious symptoms and vision loss progresses at such a gradual pace, it often goes unnoticed until it’s too late.

There are over 300,0001 Australians living with glaucoma and this disease can only be detected with a comprehensive eye examination. Glaucoma results in a slow painless loss of small areas in your side vision. These blind spots slowly enlarge to eliminate your peripheral vision so often people don’t notice a deterioration until the disease has taken hold.

Because of the slow and often unnoticed loss of side vision, glaucoma has been called the ‘silent thief of sight’.

Glaucoma comes in a variety of forms but is usually associated with a build-up of fluid pressure in the eye (known as intraocular pressure or IOP) that damages the optic nerve that links the eye to your brain. Your optic nerve transmits the signals received by the back of your eye (the retina), to your brain2. Glaucoma is a disease that affects the optic nerve, slowly destroying vision and eventually causing blindness. Sadly, there is no cure for glaucoma but it can be controlled and its progress stopped, or at least, slowed down. This is one of the reasons we recommend regular eye tests according to your eye health needs. Early detection means we can start treatment before too much vision has been lost.

What are the Symptoms

Many people with the early stages of glaucoma have no idea at all, as the disease shows few symptoms and develops slowly. The first sign is usually a reduction in side (peripheral) vision. Later, vision becomes blurred and it becomes hard to adjust to low light conditions. If you experience any of these symptoms, make an appointment with your OPSM optometrist as soon as possible*.

Who is at Risk

Although anyone may develop glaucoma, some people have a higher risk - they are people who:

  • Have a family history of glaucoma
  • Are aged over 50
  • Are of African or Asian descent
  • Have diabetes
  • Have myopia (nearsighted)
  • Have been on a prolonged course of cortisone (steroid) medication
  • Experience migraines
  • Have had an eye operation or eye injury
  • Who have a history or high or low blood pressure

What can OPSM do

With the right treatment, glaucoma can usually be controlled and further loss of sight either prevented or at least, slowed down. OPSM Optometrists can provide advice and appropriate referral for Glaucoma treatment. There are three main types of treatment:
Eye drops - This is the most common treatment designed to reduce the pressure in the eyes. The drops must be used as prescribed.
Laser surgery - This may be performed as an alternative to eye drops or if eye drops have not had the desired effect.
Surgery - In most cases this is performed after the other two options have failed to control the pressure in the eye. A new channel is created to allow fluid to leave the eye.

Sadly, the effects of glaucoma cannot be reversed and these treatments will not improve eye sight or repair vision. This is why early detection and treatment is so important.

Supporting glaucoma patients with SiGHTWiSE

OPSM is pleased to support Glaucoma Australia’s SiGHTWiSE Patient Support Program. SiGHTWiSE empowers those who have been diagnosed with glaucoma to understand their disease and make informed decisions to maintain their quality of life and preserve their vision.

What Types of Glaucoma Are there

Glaucoma comes in a variety of types. They include:
Open-angle glaucoma (OAG) - This is the most common type of glaucoma. OAG occurs when the pressure of the fluid that nourishes the inside of the front of the eye is too high, eventually damaging the optic nerve.
Angle-closure glaucoma (ACG) - This form of glaucoma is less common, with damage to the optic nerve being caused by sudden spikes in eye pressure due the fluid being blocked in the eye. It may be associated with pain and sudden blurring of vision.
Normal tension glaucoma - This occurs when there is progressive optic nerve damage and loss of peripheral vision, despite the eye pressures being within the normal range (or even below normal).
Secondary glaucoma - This can often develop as a result of other conditions such as eye injuries, cataracts, diabetes and inflammation of the eye, or the use of certain medications (particularly those containing steroids).
Congenital glaucoma - this rare form of glaucoma is present at birth, but is usually detected in infancy. It is caused by the improper development of the baby’s drainage channels.

Your OPSM optometrist will be happy to give you more details during your eye health check-up.
