What is a normal eye pressure

The eye is a globe and needs to maintain a level of pressure (intraocular pressure) to maintain proper function.

If you picture your eye as a globe inflated by pressure, you can better understand why ocular hypertension should be monitored.Eyes afflicted with this condition are far more susceptible to optic nerve damage with any increase in the intraocular pressure compared to other eyes.Intraocular pressure is the tissue pressure within the eye, which is determined by the balance between the production and drainage of aqueous humor, the clear fluid inside the eye.Tonometry is the measurement of pressure within the eye (called intraocular pressure) to determine if glaucoma is present in dogs.The pressure of the fluid inside the front or anterior chamber of the eye is known as the intra-ocular pressure (IOP).These delicate nerve fibres are responsible for carrying visual impulses from your eye to the brain.

While the average eye pressure is approximately 15, the range of normal eye pressure is much larger.

Studies have shown that certain foods can cause people to have pain or pressure in their eyes within 24 hours of eating a specific substance.

This means that your eye pressure is less than 21 This means that your eye pressure is less than 21.

If field test is normal, then we cannot label you as glaucoma patient.The normal eye pressure usually ranges between 10 and 21, with an average of 16, when measured by an eye doctor.Since the ophthalmologist you saw did a detailed fundus examination and told.

Doc has prescribed Timolol (Beta Blocker) to reduce pressure to normal level.The optic nerve carries information about vision from the eye to the brain.


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.During an eye exam, a tonometer will measure the pressure of the fluid behind the cornea.

What Is Considered High Blood Pressure? - Healthline

But if you think you have glaucoma other signs are hazy looking eyes and a lot of tearing.

Normal-tension glaucoma (also called low-tension glaucoma) is a unique condition in which optic nerve damage and vision loss have occurred despite a normal pressure inside the eye.

When the IOP is higher than normal but the person does not show signs of glaucoma, this is referred to as ocular hypertension.This condition can lead to experience vision problems and total blindness.

Blood pressure is determined by the amount of blood pumped by the heart and how easily blood flows through arteries.One 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.

Slight changes in eye pressure from one season to another — or even during the course of a day — are normal.Intraocular pressure (IOP) is the pressure exerted against the outer layers by the eyeball.Glaucoma is a group of eye diseases that cause vision loss by damaging the optic nerve, which transmits visual information from the eye to the brain.

He notes that a combination of eye drops also could be used to attempt to control the fluctuations.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.This may be because the pressure is higher than normal, or because the nerve is more susceptible to damage from pressure.Glaucoma occurs when the normal fluid pressure inside the eyes slowly rises.Your ocular condition also determines what will be normal for you. Eg. For a patient of advanced glaucoma, 21mm hg is very high where as it is normal for a person with no eye illnesses.
