Full Answer

Glaucoma is a disease that can be diagnosed by either an ophthalmologist or optometrist. One of the factors of the disease is high intraocular pressure, known as IOP. IOP is the pressure of the fluid inside the eye. When this pressure is elevated, it can cause damage to the optic nerve, which in turn causes loss of vision. The most common loss of vision occurs peripherally; however, advanced cases can cause total loss of vision.

Although there are charts available to determine if pressure is in the normal range, IOP is not the only factor. The normal range of IOP is between 12 and 22 mmHg, but there are those with pressures within that range who may have glaucoma, as well as people with pressures higher than this range who may not have glaucoma. It is imperative that people who have a family history of glaucoma have regular dilated eye examinations, even if they have normal IOP levels, so that a doctor may assess additional factors that may indicate a diagnosis of glaucoma.
