GLAUCOMA

Glaucoma is caused by a group of diseases that damage the optic nerve or information cable that carries the information from your eyeball to your brain.

It is known as the ‘sneak thief of sight’ because in many cases it slowly steals away your vision, without causing any noticeable symptoms. Usually it damages your peripheral or outside vision first, before moving towards your central vision. The vision field loss is usually permanent or irreversible. Currently there is no eye drop, tablet or medication that can reverse the damage once it’s done.

RISK FACTORS

Although there is still a lot to understand about glaucoma, some of the risk factors for developing it include:

  • Increasing age
  • raised pressure inside the eye (known as intraocular pressure or IOP) – although 50 per cent of people with glaucoma will have an IOP within what is considered to be the normal range
  • family history of glaucoma
  • African, Asian or Inuit heritage
  • past eye trauma
  • high short or long sightedness
  • prolonged use of steroid medications – oral, inhalers or topical drops
  • other systemic health issues – diabetes, migraine headaches, high blood pressure and some types of circulatory disorders.

TREATMENT

Glaucoma can be difficult to detect in its very early stages. Unfortunately there is no single investigation that can definitively diagnose the disease. Instead we need to put together multiple pieces of information from your history, examination findings and investigations, like doing a jigsaw puzzle. Sometimes we need to repeat these over many years before we can make a diagnosis.
While damage caused by glaucoma can’t be reversed, the progress of the condition can be controlled. The initial treatment is normally eye drops, which once started, are usually life-long. Sometimes surgery may be required. Newer forms of management, such as ‘micro-stents’ implanted at the time of cataract surgery, are showing promise.
