The effects of Glaucoma on your vision ...

What is glaucoma?

Optic nerve showing progressive loss of fibres.

Glaucoma occurs when the optic nerve at the back of the eye is damaged, often in association with a increase in pressure inside the eye.

There are two main types of glaucoma: primary open angle glaucoma and acute angle closure glaucoma.

In primary open angle glaucoma, the most common form, the optic nerve becomes damaged over time. Often (but not always) this is associated with an increase in eye pressure. A normal eye pressure is necessary to keep the eye healthy and functioning properly. It is regulated by the release of fluid, aqueous humour, which circulates from behind the iris into drainage channels between the iris and the cornea. If the ability to drain the fluid is compromised then fluid can build up and eye pressure will rise and can begin to damage the optic nerve.

Damage to vision occurs very slowly and the first signs may be the loss of some parts of the visual field, most commonly the peripheral, or side vision.
