Intra Ocular Pressure Assesment

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).

Normal eye pressure ranges from 10-20 mm Hg. Ocular hypertension is an eye pressure of greater than 21 mm Hg. Ocular hypertension is the most important risk factor for glaucoma.

Glaucoma is usually, but not always, associated with elevated pressure in the eye Actually, glaucoma is now considered a disease of the optic nerve, or optic neuropathy.

Generally speaking, the vision loss in glaucoma usually occurs in both eyes, and is thus termed bilateral. As in many other disease states, the vision loss may not be symmetric, that is, one eye may be worse than the other.

Vision loss due to glaucoma often begins with a subtle decrease in peripheral vision. If the glaucoma is not diagnosed and treated, it may progress to loss of central vision and blindness.

Therefore, it is important to have your eyes tested for Intra Ocular Presure available at Ho Optometrist.
