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.
An ophthalmologist typically diagnoses abnormal intraocular pressure (elevated or low) by measuring the pressure using a tonometry test. This test involves using a device called a tonometer to measure the pressure inside the eye. Abnormal intraocular pressure can be a sign of conditions like glaucoma, so it's important to have regular eye exams to monitor and manage any changes in pressure.
A barometer is used to measure atmospheric pressure. It can also measure altitude!

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.
Normal intraocular pressure is between 10 and 20 mmHg. I've also seen 15.5 +/- 2.75.
