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.

Ocular hypertension increases a person's risk of developing glaucoma. Around 10% of people with untreated ocular hypertension go on to develop glaucoma. Eye pressure, also called intraocular pressure or IOP, is measured in millimetres of mercury (mmHg) using a procedure called tonometry.ormal eye pressure ranges from 10 to 21 mmHg. Ocular hypertension is an eye pressure of greater than 21 mmHg. The condition affects around 3-5% of people over 40.
