A tonometer is a device which measures intraocular pressure (IOP). Tonometry is the procedure eye care professionals perform to determine the IOP, the fluid pressure inside the eye. It is an important test in the evaluation of patients at risk from glaucoma. Most tonometers are calibrated to measure pressure in millimeters of mercury (mmHg).
