is a series of diseases that if left untreated can cause damage to the optic nerve
resulting in gradual vision loss and eventually blindness. Damage to the optic
nerve due to glaucoma, is usually cause by an elevated intraocular pressure (IOP).
clear fluid called aqueous humor, fills the front of the eye (anterior chamber)
and provides nourishment to the tissues. Like the air in a balloon, the aqueous
also provides pressure to help maintain the shape of the eye.
ANGLE GLAUCOMA (OAG), the most common type of glaucoma, occurs when there is either
a sustained increase in fluid production or a decrease in fluid drainage. With
the imbalance in fluid flow, there is an increase in the intraocular pressure,
which in turn reduces blood flow to the sensitive tissues of the optic nerve.
Over time, as the optic nerve fibers are destroyed, peripheral (side) vision is
