What controls pressure in the eye
A layer of cells behind the iris (the colored
part of the eye) produces a watery fluid,
called aqueous. The fluid passes through a
hole in the centre of the iris (called the
pupil) to leave the eye through tiny
drainage channels. These are in the angle
between the front of the eye (the cornea)
and the iris and return the fluid to the
blood stream. Normally the fluid produced
is balanced by the fluid draining out but it
cannot escape, too much is produced, then
your eye pressure will rise. (The aqueous
fluid has nothing to do with tears)
