The treatment you receive depends upon the type of glaucoma you have and how severe it is. Therefore, not all patients with glaucoma have the same treatment. In any case, if the pressure is left untreated over a period of time, the sensitive visual structures in the eye are injured, resulting in a visual loss. How pressure in your eye is produced The eye has a spherical shape and is kept inflated by an internal pressure that is normally present. This pressure results from a steady production of a clear, watery fluid in the eye called aqueous humor.
Aqueous humor is produced in a portion of the eye called the ciliary body.
It circulates from the ciliary body forward through a sieve-like structure called the trabeculum. On its way out it passes into the canal of Schlemm, which is a larger drainage area, and then outward into your blood system. Aqueous humor is not the same as tears. It is separated from your tears by the cornea, which covers the front of the eyeball. In glaucoma, something obstructs the exit of aqueous humor from the eye, and the fluid build-up causes the pressure to become higher than normal.
