Eye pressure is the fluid pressure of the aqueous humor inside the eye. To detect your eye pressure, our doctors choose to either use the applanation tonometry or a tonopen.
Normal eye pressure ranges from 12-22 millimeters of mercury, and eye pressure of greater than 22 is considered higher than normal. High eye pressure is essential to finding glaucoma, which is damage from eye pressure to the nerves in the eye (retina) that record a picture. Signs of high eye pressure generally do not have symptoms.
