Glaucoma is a disease of the eye associated with raised pressure. We don't have any blood vessels running over the cornea at the front of the eye or we wouldn't be able to see. We get nutrients from the aqueous, a fluid similar to plasma that fills the space between the cornes and the iris, the coloured part of the eye, and then drains away. Sometimes the drainage channels become blocked and the pressure (IOP) increases and damages the nerves of the retina at the back of the eye.
