A common question asked during the eye exam is, “When is the puff coming?”  

Patients are referring to air-puff or non-contact tonometry. Tonometry is the procedure used to measure eye pressure, and this is important to diagnose and monitor glaucoma.

In non-contact tonometry, a puff of air is used to measure the pressure inside the eye.  The benefit of this test is there is no actual contact to the eye, but the air puff is sometimes very startling for patients. Most people hate that test and it isn’t the most accurate way to measure your eye pressure.

Some doctors don’t even use the air-puff test. Instead, they place a yellow drop that consists of a numbing medicine and then shine a blue light on the eye. This is done in front of the slit lamp and a small tip gently touches the eye to measure the eye pressure. This procedure is called Goldmann tonometry and is considered the gold standard for measuring eye pressure.  

Another method for checking eye pressure is the Tonopen. This is a portable, hand-held instrument that is useful when patients can’t sit in front of the slit lamp to have their eye pressure checked. The Tonopen also requires a numbing drop to be placed in the eye, and the tip gently touches the eye.

A common question related to tonometry is “what normal eye pressure?”

Normal eye pressure ranges from 10-21 mm Hg. Eye pressure doesn't have any relationship to blood pressure. Many times, people are surprised that their eye pressure is high, but they have normal blood pressure. In general, there is no diet or exercise that will significantly affect eye pressure. It is therefore important to have your eye pressure checked regularly because there are usually no symptoms of high eye pressure until it has affected your vision.
