What is it for?
Measuring your intraocular pressure.
When is this done?
Initial screening and during annual eye exams.
What actually happens?
In the air puff method, you will rest forehead on a padded support and stare straight into the examining
instrument. The instrument will blow a brief puff of air at your eye. The instrument estimates the intraocular pressure (IOP) from the change in the light reflected off the cornea as it is temporarily indented by the air puff. A clinician may perform the procedure several times for each eye.
Alternatively or additionally an optometrist may use the Goldmann tonometry (or similar applanation)
method. Anaesthetic drops containing a fluorescein dye are placed in the eyes to numb the surface. Your optometrist will ask you to stare straight ahead whilst resting your chin and forehead against special supports on an instrument called a slit lamp. A slit lamp is a special microscope with a light source which a tonometer is attached. The optometrist will direct a broad beam of blue light from the slit lamp into your eye while they gently move the slit lamp forward until the tonometer probe lightly touches your eye. By adjusting a tension dial on the tonometer he/she can directly measure the IOP of your eye.
How does it feel?
In air-puff tonometry nothing but air directly touches the eye. You will hear the puffing sound and feel a coolness or mild pressure on your eye.
Goldmann tonometry is not painful The optometrist will use anaesthetic eye drops to numb the surface of your eyes so that you will not feel the instrument touching your cornea during the test.
What does it do?
Tonometry is a measure of the intraocular pressure (IOP) or pressure inside the eye. The inside of the eye is nourished by the production fluid which must then be drained out of the eye. If there is an imbalance between the rate the fluid is produced and the rate it is drained away the IOP may increase or decrease from its normal level. Changes to the IOP may affect other structures in the eye such as the optic nerve. Increased pressure is often associated with Glaucoma.
How does it benefit you?
Optometrists and ophthalmologists perform tonometry as part of a routine eye examination to screen for eye diseases such as glaucoma.
