Glaucoma progressively damages your sight, but it’s controllable with early detection and treatment.
What is glaucoma?
Glaucoma is a disease that progressively damages your optic nerve. Your optic nerve is located in the back of your eye and plays a prominent role in helping you see. The optic nerve connects your eyes to your brain, carrying sensory information from your retina that your brain converts into images.
Glaucoma results from a gradual increase in eye pressure. Your eyes continually produce a fluid called aqueous humor, which performs a number of functions, including nourishing your corneas and lenses and maintaining eye pressure. Normally, aqueous humor flows freely in and out of your eyes, but if it can’t drain properly, it builds up, which damages the optic nerve.
