What is Glaucoma Disease?
The optic nerve at the back of the eye can be damaged by increased pressure or poor blood flow. This damage is known as glaucoma. When everything functions properly, the eye generates a clear fluid called aqueous that fills the anterior chamber between the iris and the cornea. A system of drains allows the aqueous to flow out of the anterior chamber.
Intraocular pressure is determined by the ebb and flow of the production and drainage of the aqueous. When the drains don’t function properly, the intraocular pressure increases and the damage to the optic nerve occurs. The damage is not reversible and, without treatment, will worsen until blindness results.
