Puffer Test

Most people who’ve had a comprehensive eye exam are familiar with the puffer test. A puffer test is what it sounds like: a diagnostic device focused by a technician blows a puff of air on the eye surface to measure the intraocular pressure, the “inside” pressure, of the eye.

High pressure is a key indicator of glaucoma, a series of eye diseases that attack the optic nerve.

How does a puffer test work?

Puff tests are quick and largely without discomfort. You’ll look at a light inside the machine while your technician blows a gentle puff of air upon the surface of each open eye. The device, called a tonometer, measures the eye’s resistance to the air, and calculates your internal eye pressure.

This usually takes only a few moments, and while your eye may water slightly, the procedure is generally over before you know it!

A puffer test is a part of glaucoma testing, and is a routine part of a comprehensive eye exam. Glaucoma is a serious disease of the optic nerve, and often has no outward symptoms until vision becomes very impaired—that’s why it’s so important to have a puffer test to measure your intraocular pressure every year.
