Glaucoma is a condition usually characterized by increased pressure of the fluid within the eyeball, which causes damage to the retinal nerve fibers and the optic nerve if left untreated. Pressure within the eyeball is measured in mm Hg, the same unit used to describe barometric pressure in weather prediction. The normal range of pressure within the eye is between about 12 mm Hg to 22 mm Hg.
