tonometer

Pressure inside the eye is measured using an instrument called a tonometer.

The tonometer is not a substitute or alternative for more established methods.

He made a "tonometer" from 56 tuning forks as an instrument for accurately measuring pitch.

Intraocular pressure is measured with a tonometer as part of a comprehensive eye examination.

The patient is given local anesthesia drops and the pressure is measured using a tonometer held in the hand or attached to a slit lamp.

Ophthalmologists test for glaucoma by applying an anesthetic to the cornea and then applying a tonometer, which measures pressure.

The Schiotz tonometer consists of a curved footplate which is placed on the cornea of a supine patient.

The Stuttgart Conference of 1834 recommended C264 (A440) as the standard pitch based on Scheibler's studies with his Tonometer.

Some of the forks he disposed of to the University of Toronto and the remainder he used as a nucleus for the construction of a still more elaborate tonometer.

The Maklakoff tonometer was an early example of this method, while the Goldmann tonometer is the most widely used version in current practice.

The Diaton non-corneal tonometer calculates pressure by measuring the response of a free-falling rod, as it rebounds against the tarsal plate of the eyelid through the sclera.

Gärtner is credited with the creation of a number of medical devices and apparati; one of his better known inventions being a tonometer that contained an inflatable finger cuff for measurement of blood pressure.

By resting a more sophisticated pressure sensing device, a tonometer, against the skin surface and sensing the pulsatile artery, continuous PP wave forms can be acquired non-invasively and analysis made of these pressure signals.

Ocular response analyzer The ocular response analyser (ORA) is a non-contact (air puff) tonometer that does not require topical anaesthesia and provides additional information on the biomechanical properties of the cornea.
