Internal eye
pressure is
measured at
front corneal
surface with
a tonometer
Internal aqueous fluid
may have outflow reduced
at the angle of iris and
cornea increasing pressure
Pressure from
front of eye is
transferred to
the nerves of
the retina
Nerves are effected
resulting in vision loss
Measured pressure is but
one factor in determining
diagnosis of glaucoma
Aqueous fluid is produced at the ciliary body
behind the colored iris and drains into the
trabecular meshwork at the angle formed by
the iris and the cornea. Reduction in outflow
of the aqueous fluid may result in an increase
in the internal eye pressure. This becomes a
risk factor for the development of glaucoma.
