Eye pressure or intraocular pressure (IOP) refers to the fluid pressure inside the eye. High pressure in the eye may be a risk factor for glaucoma, or may be caused by inflammation, medications, or genetic factors. It tends to increase with age. Pressure in the eye may need to be reduced during or following certain kinds of eye surgery.
Cholinergic agonists, beta blockers, alpha agonists, and other medications can work to lower pressure in the eye.
