1 Categories of training needed are determined by the job duties.  Employees who work in a shop environment (electrical, carpenter, plumbing shops, etc.) should check with their supervisor to determine additional training requirements.
Intraocular pressure (IOP) is the fluid pressure inside the eye. Tonometry is the method eye care professionals use to determine this. IOP is an important aspect in the evaluation of patients at risk from glaucoma.Most tonometers are calibrated to measure pressure in millimeters of mercury (mmHg).ntraocular pressure (IOP) is the fluid pressure inside the eye.

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.
