What is the normal intraocular pressure

Ocular hypertension is a risk factor for glaucoma but glaucoma can occur in those with a normal intraocular pressure too.Intraocular pressure (IOP) or eye pressure is the fluid pressure inside an eye and is calculated in millimeters of mercury (mm Hg).Glaucoma is a condition in which pressure is placed on the eye, causing inadequate fluid drainage in the eye.Folks most at risk for developing glaucoma include: People who are over the age of 40: As we age our eyes age as well glaucoma is most often diagnosed in people over the age of 40. People.The intraocular pressure fluctuates a lot during the day, between day and night, and on different days, months and seasons of the year.While glaucoma may develop in individuals with or without elevated eye pressure, reducing the pressure in the eye is the only proven way to stop or slow glaucoma.In glaucoma, the intraocular pressure is abnormal which causes the aqueous to fill up in the eye, thus damaging the optical nerve and hampering vision.Tonometry is a relatively simple test that can screen for diseases such as glaucoma, for which high intraocular pressure is a risk factor.

While normal intraocular pressure ranges between 12 to 21 mm Hg, an individual may have glaucoma even if the pressure is within this range.The eye pressure is known as the intraocular pressure or IOP.

It is an important test in the evaluation of patients at risk from glaucoma.Normal intraocular pressure is between 12 and 20 mg Hg, and pressure higher than 20 mg Hg may indicate the presence of glaucoma.However, there are cases where this does not happen, but the IOP is maintained at normal levels.

What is Glaucoma

The size and shape of the normal eye is maintained by the amount of fluid within the eyeball.To put intraocular pressure measurements in perspective, the national average pressure measurement in the U.S. is between 14 and 16, and normal population pressures up to 21 may be within normal range.
