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: With your head resting in the chinrest of a diagnostic machine called a slit lamp, your eye doctor uses a puff of air across the surface of the eye to measure the intraocular pressure, “inside” pressure, of the eye.

High pressure is a key indicator of glaucoma, a series of eye diseases that attacks 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 eye doctor blows a gentle puff of air across the surface of your open eye. A 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 might 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 doesn’t present itself until vision becomes impaired—that’s why it’s so important to have a puffer test to measure your intraocular pressure.

A Message to Our Patients

Although the Governor has rescinded the mask mandate, we have been advised by the Texas Optometry Association that Optometrists follow Infection Control Guidance for Healthcare Professionals recommended by the Centers of Disease Control (CDC). In addition, most, but not all, of our employees are vaccinated. We are hoping to have our entire staff vaccinated by May 1st, 2021.

Until all staff members are vaccinated, the continued safety and well-being of our patients and staff is our number one focus. Masks will be required to be worn by all patients, visitors, and staff while in our practice. We will also continue to follow the CDC’s guidelines and recommendations throughout the practice.

We thank you for your understanding and helping us protect our patients, families, and staff.
