What is glaucoma? 

Glaucoma is an eye disease in which the pressure inside the eye progressively damages the optic nerve. Glaucoma is a problem not only when the pressure is high; in some people it can cause damage when the pressure is normal or low. 

What causes glaucoma? 

The fluid pressure that builds up inside the eye may be caused by producing too much fluid or the fluid being clocked from leaving the eye. When this pressure builds up, it can cause damage to the sensitive optic nerve cells at the back of the eye. Optic nerve cells carry messages from your eye to your brain and once damaged vision is lost permanently. 

Who gets glaucoma? 

Glaucoma is more likely to occur, and you should have your eyes checked regularly for glaucoma if: 

How will I know if I have glaucoma? 

Commonly, glaucoma causes no pain or discomfort, does not affect how clearly you see and progresses slowly. You may not even know if you have glaucoma. Sometimes the pressure will rise quickly and cause intense eye pain and redness. This type of glaucoma is an emergency and needs treatment as soon as possible.  

How is glaucoma diagnosed? 

As part of your eye examination our optometrists will: 

It is common for our optometrists to put eye drops in your eyes when checking for glaucoma. They may need to take a photograph of the optic nerve for comparison at your next eye exam. Using these results and information from other tests, our optometrists will be able to tell you if you have glaucoma or are at risk of developing glaucoma.  

Can glaucoma be treated?

While glaucoma cannot be completely prevented and vision loss from glaucoma is permanent, early detection and treatment can reduce damage to the optic nerve and loss of vision. Glaucoma is usually treated with prescription eye drops. Once diagnosed with glaucoma you will need treatment for life. Sometimes eye drops alone will not control the damage to the optic nerve and laser treatment or surgery is needed.  

What support is there for glaucoma sufferers?
