What is an ophthalmologist testing for when they do an eye pressure test?

Table of Contents

This test measures the thickness of your cornea, which helps your eye doctor determine your risk for glaucoma. Your ophthalmologist numbs your eye with drops, then touches your eye with a small probe. The test is also called pachymetry.

How accurate is the air puff test for glaucoma?

Is the air puff test still used?

Many eye doctors have ditched the air puff test and switched to other, more reliable methods of tonometry to measure eye pressure and help detect glaucoma.

How is a glaucoma test performed?

In assessing your glaucoma, the ophthalmologist will dilate your eyes so that he or she can get a magnified, 3D view of your optic nerve. This helps to determine the status of your optic nerves and glaucoma. He or she will assess the shape, color, depth, size, and vessels of the optic nerve.

Does the air puff test hurt?

The eye air puff test is truly what it sounds like: a machine called a tonometer will blow a light puff of air into your eye, while you look into a light. Though quick and painless, the test reveals vital information on the actual pressure your eyes can withstand. This is called your intraocular pressure (IOP).

How long does a glaucoma test take?

What is considered dangerously high eye pressure?

While ocular hypertension isn’t an eye disease in itself, it is an indication that you could develop glaucoma. Your eye pressure is measured in millimeters of mercury, expressed as mm Hg. Normal eye pressure is between 10 to 21 mm Hg. High intraocular pressure is greater than 21 mm Hg.
