What Causes Glaucoma?
Normally, a clear fluid called the aqueous humor flows through your inner eye, bathing it constantly and nourishing the surrounding tissue. With glaucoma, the fluid drains too slowly and builds up causing pressure inside the eye to rise. The pressure, in turn, affects the optic nerve, which is like an electronic cable carrying messages to your brain – messages that normally result in sharp, clear vision. If the entire nerve is destroyed, blindness is the result.
