What is eye pressure?

Eye pressure, or ocular pressure, refers to the internal pressure of the eyeball in mm Hg. This ratio defines the relationship between the production of ocular fluid (aqueous humor) and the fluid that flows out through the drainage canal. When a balance cannot be sustained between the production and drainage systems of the eye, dysfunctions or disease can occur. Eye pressure is, for this reason, used as a partial indicator of overall optical health. The typical ocular pressure is between 12 and 22 mm Hg.
