How do they test the pressure in your eyes?

Tonometry measures the pressure within your eye. During tonometry, eye drops are used to numb the eye. Then a doctor or technician uses a device called a tonometer to measure the inner pressure of the eye. A small amount of pressure is applied to the eye by a tiny device or by a warm puff of air.

What is IOP test?

Intraocular pressure (IOP) is the fluid pressure inside the eye. Tonometry is the method eye care professionals use to determine this. IOP is an important aspect in the evaluation of patients at risk of glaucoma. Most tonometers are calibrated to measure pressure in millimeters of mercury (mmHg).

What is used to measure pressure in the eye?

Tonometry is a test to measure the pressure inside your eyes. The test is used to screen for glaucoma and to measure how well glaucoma treatment is working. People over age 40 years, particularly African Americans, have the highest risk for developing glaucoma. Regular eye exams can help detect glaucoma early.

How is fluid pressure measured in the eye?

Routine eye exams often look at your IOP. You may have sat through an examination in which a puff of air hit your eye. This device used to be the standard for optometrists and ophthalmologists to measure your eye’s fluid pressure, but a newer, more accurate device may be used instead.

What kind of test do optometrists do for eye pressure?

Optometrists are trained and educated to perform different procedures using different equipment and methods. An eye pressure test is called tonometry. This test is used to diagnose glaucoma and other eye diseases. Since glaucoma has no symptoms, it is very hard to detect. The first step in a tonometry test is usually eye drops.

How is the tonometer used to measure eye pressure?

The tonometer is briefly placed on the cornea to determine eye pressure. Before the test, you’ll receive anesthetic drops to numb the eye, so you won’t feel anything. This test estimates the pressure in your eye using a puff of air. Your doctor will warn you to expect a quick pulse of air, which may be surprising.

Which is the gold standard eye pressure test?

In most ophthalmologist’s offices, eye pressure is measured using “Goldmann applanation tonometry,” and this is considered a “gold standard” eye pressure measurement. In this test, the eyes are anesthetized with numbing drops.

How do I check my eye pressure?

Your doctor can check your eye pressure a couple of different ways: Tonometer. After special numbing drops are put in your eye, your doctor gently holds this pencil-shaped device against the outside of your eyeball. The reading tells how well your cornea pushes back.

Why to check eye pressure?

Measuring your eye pressure is an important part of a comprehensive eye examination. If your eye pressure becomes higher than normal, you may be at risk for developing eye diseases such as glaucoma. 1  High eye pressure can damage the delicate nerve fibers in the back of your eye, sometimes resulting in blindness.

What are the symptoms of high pressure in the eye?

The medical term used to describe high eye pressure is ocular hypertension. It is caused when the watery fluid production, found inside the eyes, goes up or there is inadequate drainage. The two most prevalent symptoms are chronic pain in the eyes and headache. These symptoms are often accompanied by redness in the eyes and blurred vision.

What does eye pressure check?

Optometrists check the pressure placed on them by the fluid in the eyes. This pressure is called intraocular pressure and should measure between 10 mmHg and 21 mmHg. Measurements that are higher than normal can be a sign of early glaucoma or retinal detachment.
