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.

COVID-19 Update

Your health and well-being is our top priority at Focusing on Eye Care. In following recommendations provided by the CDC, we have implemented protocols at our office in order to continue to protect the health of our patients and our team.

Every patient and their guest will be asked to fill out a COVID-19 questionnaire. Should you or a guest have flu-like symptoms, fever, exposure to a known person with COVID-19 or have tested positive for COVID-19, you will be asked to reschedule your appointment for a later date until you are well or clear of any potential illness for a minimum of 14 days.

We ask that patients please come to their appointment unaccompanied. If you are requiring a guest to accompany you, we are limiting the number of guests in our facilities to 1 per patient, and we ask that you only bring a guest with you if it is absolutely necessary to avoid crowding in the office.

In addition, we are requiring all employees, patients, and their guests to wear face coverings while in our facilities at all times.

Thank you for all your cooperation as we continue to help you with your eye care needs and for helping us reduce the spread of COVID-19.

Stay Well,

Focusing on Eye Care
