Tonometry Defined
The following is in context to Glaucoma, because it's common for a single word to have multiple meanings you will find additional research links near the bottom of the page.
"The use of a device to measure the pressure in the eye. There are two types of tonometry:
* Air Puff: This is the only type of tonometry that does not touch
the surface of the eye. The patient sits facing the instrument, and
a warm puff of air is directed at the eye.
* Applanation: The patient’s eye is first treated with numbing
drops and a stain called fluorescein. The tonometer is then placed
gently on the cornea, and a very small amount of pressure is applied to the cornea. The patient may sit in front of the tonometer or a hand-held tonometer may be used."
