Glaucoma is a group of eye diseases in which the optic nerve, which connects your eye to your brain, is damaged by the pressure of the fluid inside your eye.

Normal Eye Pressure - Treating HypertensionWhile the average eye pressure is approximately 15, the range of normal eye pressure is much larger.Even so, this does not mean that if you have a pressure of 22 or higher it is.
Prevent Glaucoma Naturally - HealthierTalk.comWhen the IOP is higher than normal but the person does not show signs of glaucoma, this is referred to as ocular hypertension.Normal eye pressure can vary from 10 to 21 mmHg (millimeters of mercury) throughout the day, but if this pressure varies outside of the normal range, it can cause irreversible damage.
During a comprehensive eye exam, your eye care practitioner will measure your IOP and compare it with normal levels.The most sensitive and specific test for glaucoma is the field test.
Intraocular pressure is measured using an instrument called a tonometer.An eye pressure reading of 21 mmHg (millimeters of mercury) or higher generally signifies ocular hypertension.Despite this being normal, many people have the pressure ranges from 10 to 24 mm Hg.Standing on your head, lifting heavy weights or drinking a cup of coffee can all cause a temporary change in eye pressure, but it is only when eye pressure remains too high or too low for a long period of time that it is a cause for concern.Glaucoma is a disease that damages the optic nerve, which connects your eye to your brain so you can see.As long as the production and absorption or drainage of aqueous humor is equal, the intraocular pressure remains constant.
Continually high pressure within the eye can eventually damage the optic nerve and lead to glaucoma or permanent vision loss.

Glaucoma - Singapore National Eye CentreIn the past, the level of the intraocular pressure was used to define and diagnose glaucoma.The method of measuring eye pressure is called tonometry and is done with a device called a tonometer.Elevated eye pressure is often — but not always — associated with glaucoma.Ocular hypertension is an eye pressure greater than 21 mm Hg.
Glaucoma symptoms - American Academy of OphthalmologyOne of the most common threats to vision is glaucoma, damage to the nerve that takes visual signals from the eye to the brain, is often caused by elevated intraocular pressure.
It is best to discuss with your ophthalmologist what they consider to be your target pressure or target range.This damage is irreversible and can lead to blindness in advanced cases.
Glaucoma Treatment - Richmond Eye Associates | VirginiaIf you suspect glaucoma go to the eye doctor so they can diagnose you. glaucoma if left untreated can causes blindness.I guess I am just looking for some information as to others peoples experiences.
Normal-tension glaucoma missed by typical eye-pressureAlso, there are many people with pressures under 21 who develop glaucoma.
The eye is a globe and needs to maintain a level of pressure (intraocular pressure) to maintain proper function.Tonometry is the method eye care professionals use to determine this.An optometrist has to spot damage to the optic nerve at the back of the eye or use a field-of-vision test to measure any loss of peripheral sight.
