Eye pressure is also called intraocular pressure (IOP) and is measured with a special tonometry device. Pressure is recorded in millimetres of mercury (mmHg). Normal eye pressure ranges from 10 to 21 mmHg. Ocular hypertension is defined as an eye pressure of greater than 21 mmHg on two consecutive occasions without glaucoma changes being present. The optometrist or ophthalmologist will verify the eye pressure findings with a procedure called pachymetry to measure the corneal thickness with an ultrasound probe.
