What Is Glaucoma

Glaucoma is a group of conditions in which the drain for the watery fluid made by the lens muscle is blocked by various means, resulting in a higher than normal pressure within the eye. The drain is located in the anterior chamber of the eye, at the angle formed where the clear cornea meets the iris.

The high pressure causes damage to the tissues of the eye and results further in damage to the optic nerve which make up the surface nerves of the retina. Finally, the width and depth of one's vision is affected, causing visual field defects or constriction. Treatment does not regain lost vision. If glaucoma is not treated, it tends to progress to full blindness (no light perception).
