Glaucoma Puff Test: The Little Puff of Air That Could Save Your Sight

If you’ve ever had an eye test, it is likely you are familiar with the glaucoma puff test, but why exactly is it necessary? To answer this question, we first need to discuss what is glaucoma, and why a screening test is a good idea.

What is a glaucoma puff test? 

The glaucoma puff test, also called non-contact tonometry, is a screening procedure used to measure the pressure inside the eye (intraocular pressure). It involves a small puff of air directed at the eye, and a sensor measures how the eye responds to this puff, helping assess the risk of glaucoma.

Why is the glaucoma puff test necessary? 

The test is crucial because it helps detect high intraocular pressure, which is the main risk factor for glaucoma, a condition that can cause irreversible vision loss. Since glaucoma often has no symptoms until vision is lost, early detection through this test is essential for preventing further damage.

How does the puff test help diagnose glaucoma?

The puff test measures intraocular pressure. High pressure inside the eye increases the risk of glaucoma, even if no symptoms are present. If high pressure is detected, further tests are performed to assess the health of the optic nerve at the back of the eye, where the damage caused by glaucoma occurs.

Is the puff test uncomfortable?

While the puff of air might seem uncomfortable and may startle some people, the glaucoma puff test is quick, painless, and non-invasive. It provides valuable information about eye health without the need for direct contact or dilation of the pupils.

What happens if my intraocular pressure is high during the test?

If high intraocular pressure is detected, an optometrist may perform additional tests to assess your risk of glaucoma. If any issues/problems are detected, treatments such as prescription eye drops, can help reduce eye pressure and preserve vision. 

Can the puff test detect other eye conditions besides glaucoma?

Yes, while the primary purpose of the puff test is to check for glaucoma, abnormal pressure readings can also indicate other eye conditions that may require further investigation, making it a valuable part of a comprehensive eye exam.

How effective is the air puff test?

The air puff test is an effective and non-invasive way to measure intraocular pressure, which is a key indicator of glaucoma risk. While it cannot diagnose glaucoma on its own, detecting elevated eye pressure through this test helps identify those individuals who may need further evaluation, making it an essential tool for early detection and prevention of vision loss.
