I had no problems with my eyes and was discharged. When I informed the Walmart optician of my experiment and the results, they remeasured the right, this time yielding 29. Increased pressure within the eye can be a sign of glaucoma, a common and potentially very serious eye problem, if it is not detected and treated promptly.. Why Eye Pressure Matters. Another way to check eye pressure is to use a yellow drop that temporarily anesthetizes the eye. Eye pressure test: A routine part of every routine eye exam that measures the fluid pressure inside the eye. The test is called tonometry.. A puff of air is directed at the open eye. [18]. Eye test, Tonometer. Although Goldmann applanation tonometry is still the gold standard for measuring IOP, it is not ideal. Air Puff Tonometry. However, the day after the pressure check with puff of air in my left eye (which is relatively floater free and has only three or so) I noticed a new floater appear..Iv'e had the The quick puff of air flattens the patient's cornea in a non-invasive way, which means the eyes do not have to be numbed before the test. While you look at a light inside the machine, the doctor or a trained assistant will puff a small burst of air at your open eye. The puff of air flattens your cornea and the instrument senses the deflection and calculates your IOP. Unfortunately, my opinion on the usefulness of air puff tonometers for research and home eye pressure monitoring is in conflict with the medical establishment's position. By measuring the response of the eye to the puff of air, the doctor can make a rough estimate of the intraocular pressure. The test requires patients to sit in a chair and lean toward a machine that puffs a small blast of air into each eye. Here you will receive the latest in eye care treatment, answers to your questions, and the latest selection of vision care products at great prices.

The eye pressure test is called tonometry, and the most common method is known as “applanation,” in which a tiny instrument contacts the surface of the eye after it is numbed with an eye drop. It is painless and quick, but does require your cooperation. The value that is measured is the amount of time it takes for the cornea to be flattened a specific amount, meaning that the longer it takes for the air puff to flatten the eye, the higher the internal pressure. One common question we get asked a lot is whether we do an “Air Puff” eye test as part of the eye exams we do. Non-contact tonometer. The Non Contact Tonometer (NCT), casually referred to as the air puff machine, is a device that measures intraocular pressure. What Is No-Puff Glaucoma Testing Like? The pressure inside the eye is measured from the outside. The pressure being applied will be noted on the specialized machine used for the test. Non-contact tonometer or a pneumotonometer involves applying a quick puff of air pressure to the patient's eye through an instrument. The MD readings were 24 left and 23 right. “We have known for years that Goldmann applanation tonometry is flawed because of the different corneal parameters that can affect the accuracy,” says Leon Herndon, MD, associate professor of ophthalmology in the Glaucoma Service at Duke University Eye Center. This is part of a test which measures your intraocular pressure (IOP) using a tonometer - a raised IOP can indicate a problem with the eye such as glaucoma. If they don't offer one of the other ways, find somebody who does. I personally do NOT perform the air-puff test because I never liked to be puffed and know too many other people whose sole memory of their last exam is "that damn air puff machine". Tonometry tests measure the pressure of the eye by briefly flattening the cornea. It’s like pressing a balloon to check for air.

Although you think the machine will touch your eye, it won't! High pressure in the eye can cause glaucoma, or vision loss due to damage to the optic nerve.
