I thing glaucoma test? I could be wrong but My Grandma has glaucoma and she said something about "eye fluid pressure"
A tonometer is a device used to measure the pressure inside the eye, known as intraocular pressure. This measurement is crucial in diagnosing and monitoring conditions like glaucoma, where high intraocular pressure can cause damage to the optic nerve.
Tonometry measures intraocular pressure (i.e. checks for glaucoma).
Tonometry is the test that measures intraocular pressure.
A tonometer is the medical term for the instrument used to measure the pressure in the eye to detect glaucoma. The tonometer shoots a blast of air into the eye, directly into the pupil.A tonometer is used to measure eye pressure.
The procedure performed to check the intraocular pressure of the eye is called tonometry. This test measures the pressure inside the eye and is commonly used to screen for glaucoma.
Intraocular pressure above 21 mmHg is considered elevated and may be harmful to the eye. Prolonged high intraocular pressure can damage the optic nerve, leading to conditions such as glaucoma. It is important to monitor and control intraocular pressure to prevent vision loss.
Tonometry may be included in an eye examination to measure the intraocular pressure, which can help in diagnosing conditions such as glaucoma.

He may suspect it based on the physical exam if he sees an altered "cup to disc ratio" , which basically means that the optic nerve is being pushed back by the pressure. He confirms the diagnosis with a device called a tonometer that either presses on the cornea or blows a puff of air against it to measure the resistant to movement and infers the pressure.
A barometer is used to measure atmospheric pressure. It can also measure altitude!
Normal intraocular pressure is between 10 and 20 mmHg. I've also seen 15.5 +/- 2.75.
Fluid pressure within the eye is typically measured using a tonometer, which applies gentle pressure to the cornea to estimate the pressure within the eye. The most common method is called non-contact tonometry, which uses a puff of air to measure intraocular pressure. Another method is applanation tonometry, which involves flattening a small area of the cornea with a special tool to measure the pressure.
