Target intraocular pressure

Target intraocular pressure is the level of pressure inside the eyes that a doctor tries to maintain while treating open-angle glaucoma. Keeping the pressure at or below the target level reduces the risk of damage to the optic nerve and may help slow the progression of glaucoma.

The target pressure is based on the degree of optic nerve damage, the amount of visual field loss, and, to a lesser degree, the initial pressure in the eye and how widely it varies each time it is measured. A doctor uses a test called tonometry to monitor pressure in the eyes.
