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.

The causes for elevated eye pressures are only partially known. In some individuals, a specific cause can be identified. High eye pressure is always related to some increased resistance or obstruction of the normal outflow of fluid inside the eye. Inside the eye, fluid is constantly being manufactured and has to drain from inside the eye. The pressure will only elevate if the drainage system in the eye is somehow not functioning properly. With injury or trauma, for example, the drainage system can be blocked in the eye, hopefully only temporarily. However, in most individuals with elevated eye pressure and glaucoma, the drainage system appears normal but is not functioning properly.
