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.

A normal result means your eye pressure is within the normal range. The normal eye pressure range is 10 to 21 mmHg. The thickness of your cornea can affect measurements. Normal eyes with thick corneas have higher readings, and normal eyes with thin corneas have lower readings. A thin cornea with a high reading may be very abnormal (the actual eye pressure will be higher than shown on the tonometer).
