What is Glaucoma?
Glaucoma is known as the "sneak thief of sight". It is an eye disease in which the passages that allow fluid in the eye to drain become clogged or blocked. This results in the amount of fluid in the eye building up and causing increased pressure inside the eye. This increased pressure damages the optic nerve which connects the eye to the brain. The optic nerve is the main carrier of vision information to the brain. Damage to it results in less information sent to the brain and a loss of vision. Poor blood flow behind the eye may also contribute to glaucoma.
