Definition of Intraocular pressure
Intraocular pressure: The pressure created by the
continual renewal of fluids within the eye. The intraocular pressure
is increased in glaucoma.
In acute
angle-closure glaucoma, the intraocular pressure rises because the
canal into which the
fluid in the front part of the eye normally drains is suddenly
blocked.
In chronic
glaucoma, there is a gradual imbalance between the production and
removal (resorption) of
the fluid in the back part of the eye (with supply exceeding
demand).
