Intraocular pressure (IOP) has been found to be associated with systemic blood pressure levels in population based studies. The relation appears to be reasonably consistent across the range of values of IOP and both systolic and diastolic blood pressures.
Does eye pressure test hurt?
The eye pressure test is sometimes known as 'the glaucoma test'. Usually, the test involves blowing a puff of air on your eye – this is known as non-contact tonometry. This test does not hurt, but it may tickle or make you jump.
Does a tonometer touch your eye?
Noncontact (or air-puff) tonometry does not touch your eye but uses a puff of air to flatten your cornea. This type of tonometry is not the best way to measure intraocular pressure. But it is often used as a simple way to check for high IOP and is the easiest way to test children.
What is used to measure IOP?
Applanation tonometers are currently considered the most reliable instruments for an accurate IOP measurement. Such tonometers use the Imbert–Fick law: P = F/S, in which P is pressure, S represents the surface of the flattened area, and F is the force needed to flatten a fixed corneal area.
What does an eye doctor check?

Where does aqueous humor flow through the eye?
In a healthy eye, aqueous humor, or fluid, continuously moves through the eye. As new fluid is produced, earlier fluid drains out through the eye’s anterior angle, where the cornea meets the iris. The fluid is sent from the eye to the uveoscleral drains and trabecular meshwork, down the back of the nose and throat.
Why does my eye pressure increase?
This drainage system must remain clear and intact in order to maintain normal IOP. If a problem arises and the fluid is no longer able to drain efficiently, a buildup of fluid can occur, consequently causing an increase in eye pressure .

What is the IOP of the eye?
Eye pressure, also known as intraocular pressure (IOP), is the fluid pressure inside the eye. Used as a measurement for diagnosing eye disease, periodic measurement of your IOP is essential for your eye health. For example, ocular hypertension (increased IOP) is a clinical indicator of glaucoma with the goal of treatment to lower the pressure.
What does it mean when IOP is decreasing?
A decrease in IOP can be an indicator for the progressive detachment of the retina and choroid. 2 Furthermore, differences in the eye pressure between eyes can be a sign of iritis or retinal detachment. 2 .
What is Normal Eye Pressure?
Intraocular pressure (IOP), is measurement of the fluid pressure inside the eye that can help diagnosis current eye disorders and give you insight into your eye health . Pressure from aqueous humor fluid drains from the eye and new fluid replaces it as needed. It creates a homeostatic balance that regulates eye pressure.
How does glaucoma affect the eye?
