The one an ophthalmologist measures is more accurate because he touches the eye directly, that way obtaining a better/acurate measurement. 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. Well to be frank, the air puff presents an important test that gives your eye doctor useful information on the health of your eyes. Eye pressure test: A routine part of every routine eye exam that measures the fluid pressure inside the eye. I do not like the air puff test. “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. The puff test is a non-contact tonometry test that puffs a small burst of air into your eye. The pressure being applied will be noted on the specialized machine used for the test. Goldmann tonometry (the blue light with the drops) is the highest standard - it is the most reliable, most repeatable, most widely used measure of eye pressure. 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.. This jet then delivers a quick puff of air onto the surface of your eye. 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. The air puff test is called the Non-Contact Tonometer and can only be done at your eye doctor’s office. The tonometer is critical because it measures the pressure inside of your eye. Another way to check eye pressure is to use a yellow drop that temporarily anesthetizes the eye. The eye doctor has other ways of measuring your pressure and they will NOT make you jump. This is a subject area that many doctors approach with a strong bias (and an emotionally-charged attitude). properties, ocular fluids and the air puff was studied before theoretically, numerically and clinically but with assumptions for the fluid structure interaction effect. I was referred to the hospital with suspected glaucoma, 6 weeks later when i was seen by the hospital the reading was 20! The pressure inside the eye is measured from the outside. This is an important test to check eye pressure and screen for glaucoma. 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". This is called your intraocular pressure (IOP). Non-contact tonometer or a pneumotonometer involves applying a quick puff of air pressure to the patient's eye through an instrument. Pretest optometric technicians perform air puff tonometry tests. It’s like pressing a balloon to check for air. I had no problems with my eyes and was discharged. 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 In the past, this test was not as accurate as other types of tonometry, but newer technology has improved its accuracy. 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. [18]. High pressure in the eye can cause glaucoma, or vision loss due to damage to the optic nerve. Dr. S and Dr. E show us how the test works.... And Dr. E doesn't handle it very gracefully. Many patients have mentioned a fear or distaste for the “eye puff” test. If they don't offer one of the other ways, find somebody who does. A tonometry test measures your intraocular pressure. It does so by gauging the eye's focusing power and how it processes light. “Puff of air.” Your doctor could also use an instrument that blows a small puff of air at your eye while you look into a light. The Non Contact Tonometer (NCT), casually referred to as the air puff machine, is a device that measures intraocular pressure.
