Glaucoma is an eye disease that can cause vision loss and is potentially blinding. It runs in families. If someone in your family has glaucoma, you are up to 10 times more likely to develop glaucoma. You probably have never noticed or even thought about glaucoma, as it is rarely discussed. In Australia, approximately 300,000 people have glaucoma. However, about half of these people don’t even know they have it. Generally, there is no pain associated with glaucoma, and the loss of sight is gradual. Peripheral vision (side vision) is usually affected first, and many people don’t even notice it’s gone.
In glaucoma, the optic nerve, located at the back of the eye, is damaged. This may happen if the pressure in the eye increases. Fluid in the eye should drain away, lowering eye pressure. But in glaucoma, the fluid doesn’t drain away properly, slowly destroying the optic nerve, which eventually leads to blindness. The optic nerve can also become damaged by certain medicines, such as steroids, and some medical conditions, such as diabetes and high blood pressure. Read More >
