Glaucoma is increased pressure within the eye. It is an emergency situation, and if not treated immediately, can lead to blindness.
Cells inside the eye produce a clear fluid (“aqueous humor”) that maintains the shape of the eye and nourishes the tissues inside the eye. The balance of fluid production and drainage is responsible for maintaining normal pressure within the eye. In glaucoma, the drain becomes clogged but the eye keeps producing fluid. Therefore, the pressure in the eye increases. The increased pressure in the eye actually can cause the eye to stretch and enlarge.
