Is there an alternative to the eye puff test?
The second alternative to the air puff test is called electronic indentation tonometry. According to the National Library of Medicine, an eye care professional measures your eye pressure during this test, with a handheld, pencil-shaped device after numbing eye drops have been administered to ease discomfort.
Why do opticians puff air in your eye?
Answer: 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. The puff of air flattens your cornea and the instrument senses the deflection and calculates your IOP.
How accurate is the puff test for glaucoma?
“Puff tonometry” is a good screening test for eye doctors, but can sometimes overestimate pressures. This test is not as accurate as traditional tonometry, but is very sensitive in picking up pressure problems.
Is a glaucoma test necessary?
If you are younger than 40 and have no known risk factors for glaucoma, the American Academy of Ophthalmology (AAO) recommends that you have a complete eye exam every 5 to 10 years. This includes tests that check for glaucoma. The AAO suggests more frequent routine eye exams as you age.
Is air puff tonometry accurate?
Results: Air puff tonometer had an overall accuracy of 49.70% to measure intraocular pressure within ± 2 mm Hg difference compared with Goldmann applanation tonometer. At all ranges of intraocular pressures Air puff tonometer measured higher (mean 2.87 mm Hg) values than Goldmann applanation tonometer.

How accurate is air puff tonometry?
How do you check eye pressure in fingers?
Place the tips of both index fingers on the closed upper eyelid. Keeping both fingertips in contact with the upper eyelid, apply gentle pressure through the closed eyelid, first gently pressing on the eye with the right index finger, then with the left, and then with the right again (Figure 1). Repeat on the other eye.
What is the pressure test on eyes for glaucoma for?
Tonometry is a quick and simple test that checks the pressure inside your eyes. The results can help your doctor see if you’re at risk for glaucoma. Glaucoma is a disease in which the nerve of the eye (the optic nerve) is gradually damaged over time, resulting in a loss of vision.
