tonometer [tō′näm·əd·ər]

(medicine)

An electronic instrument that measures hydrostatic pressure within the eye: when placed in position, a tiny movable plate is pressed against the eye, flattening a circular section of the cornea (no eyeball anesthesia is required); a current is then sent through a small electromagnet, of such value that it will just pull the plate away from the eye; the value of the current is proportional to eye pressure; a measurement can be made in about 1 second; used in diagnosis of glaucoma. Also known as electronic tonometer.

Tonometer

an instrument for measuring pressure or tension—specifically, blood pressure in the arteries, intraocular pressure, and muscle tone or tension.
