What is Glaucoma?
Glaucoma is an eye disease that causes painless and irreversible optic nerve damage. Your optic nerve is the part of your eye that is responsible for carrying images from your retina (the light-sensing tissue in your eye). These images are communicated to your brain, so that it can make sense of the images, thus giving you the sense of sight. However, when a patient experiences glaucoma optic nerve damage, their eyesight can be severely diminished.
The eye is constantly producing and circulating a clear aqueous humor that moves through drainage canals of the anterior chamber angle in the front of the eye near the iris. When this clear fluid is unable to escape, often due to a blockage, fluid builds in the eye and increases pressure on the optic nerve, which is known as Glaucoma. Glaucoma, if left untreated, can lead to vision loss.
