What is Normal Eye Pressure.

Normal eye pressure glaucoma. The reading can vary by body position time of day and factors like medication or fluid intake. Each persons normal IOP is different but generally a pressure higher than 21 mmHg is considered to be suspicious for glaucomahigh pressures that can damage your optic nerve. Most kinds of glaucoma involve elevated eye pressure.

To be considered normal eye pressure the measurement should be between 10 to 20 mmHg. By definition people with normal-tension glaucoma have open normal appearing anterior chamber angles. Many people with glaucoma have IOP of greater than 21.

The Glaucoma Research Foundation defines normal eye pressure as a measurement that falls between between 12 and 22 mm Hg. When the IOP is higher than normal but the person does not show signs of glaucoma this is referred to as ocular hypertension. Even so this does not mean that if you have a pressure of 22 or higher it is abnormal.

Normal-tension glaucoma NTG also known as low tension or normal pressure glaucoma is a form of glaucoma in which damage occurs to the optic nerve without eye pressure exceeding the normal range. However in normal-tension glaucoma IOP can run below 21 or even below 10. So the higher the pressure in the normal range the worse is the glaucoma.

Every individual and every eye is differentThere are many patients with pressures in the mid-20s who do not have glaucoma and they can be followed with routine eye examinations by their eye care specialist. Normal intraocular pressures average between 12-22 mm Hg. Elevated eye pressure with no other symptoms is ocular hypertension.

There is debate among glaucoma experts whether NTG is a separate entity from primary open angle glaucoma POAG or just another form. About 90 percent of people will fall between a pressure of 10 and 21. The mm Hg refers to millimeters of mercury which is a scale for recording the eye.

As part of a complete eye exam your ophthalmologist or an assistant will measure your eye pressure. In general a normal pressure range is between 12-22 mm Hg. When we study open angle glaucoma patients with pressures in this range the eyes that are higher than 15 are more likely to be more damaged than those below 15.

What is considered normal eye pressure. Also called low-tension or normal-pressure glaucoma normal-tension glaucoma NTG is a condition in which the optic nerve is damaged without eye pressure exceeding the average range usually between 12-21mm Hg. Having eye pressure thats too low or too high can damage your vision.

Eye pressure is measured in millimeters of mercury like the way a thermometer measures temperature using mercury. Normal eye pressure ranges from 12-22 mm Hg and eye pressure of greater than 22 mm Hg is considered higher than normal. Normal eye pressure is usually considered to be between 10 and 20 millimeters of mercury mmHg.

Persons without glaucoma have eye pressures between 10 and 20lets call this the normal range. The last part mm Hg stands for millimeters of mercury the unit of measurement for inner-eye pressure. During an eye exam a tonometer will measure the pressure of the fluid behind the cornea.
