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.

Watch this video that explains what glaucoma is and who is at risk for the disease. A: Normal pressure in the eye is between 12 and 21mm Hg. Some patients are fortunate in that their optic nerves can tolerate pressures outside this range. If there are no other signs of glaucoma (visual field defect or optic nerve changes), then high pressures can be followed and simply observed.
