The shape of the front part of the eye is maintained by a fluid
called aqueous humor.
Aqueous humor is produced by and removed from the eye at a constant
rate [about 1 tsp (5 mL) a
day] to maintain a constant pressure in the front (anterior) chamber of the
eye. While pressure in the eye varies throughout the day, the normal pressure
within the eye is 10 mm Hg to 21 mm Hg.
