tonometry /to·nom·e·try/ (-ĕ-tre) measurement of tension or pressure, particularly intraocular pressure.
digital tonometry estimation of the degree of intraocular pressure by pressure exerted on the eyeball by the examiner's finger.
Tonometry The measurement of pressure. Mentioned in: Glaucoma
tonometry [tōnom′ətrē] the measuring of intraocular pressure by determining the resistance of the eyeball to indentation by an applied force. Several kinds of tonometers are used. The air-puff tonometer, which does not touch the eye, records deflections of the cornea from a puff of pressurized air. The Schiötz impression and the applanation tonometers record the pressure needed to indent or flatten the corneal surface. Applanation tonometry at the slit lamp is considered most accurate. Schiötz tonometry is rarely done today. tonometry [to-nom´ĕ-tre] measurement of tension or pressure, e.g., intraocular pressure. digital tonometry estimation of the degree of intraocular pressure by pressure exerted on the eyeball by the finger of the examiner. gastric tonometry monitoring of the gastric intramucosal pH to obtain early indications of inadequate tissue oxygenation; the sensitive nature of the mucosa allows for monitoring of metabolic changes produced by hypoxia well in advance of the other more common indices of hypoxia.
tonometry measurement of tension or pressure, e.g. intraocular pressure. See also tonometer. digital tonometry
estimation of the degree of intraocular pressure by pressure exerted on the eyeball by the finger of the examiner. tonometry Measurement of intraocular pressure with a tonometer. See intraocular pressure; tonometer.
tonometry Blood gases See Blood gas analysis Ophthalmology A technique that measures intraocular pressure–normal is ≤ 20 mm Hg by contact–indentation of, or applanation on or noncontact–by a puff of air on the outer part
of the eye Indications Diagnose and manage glaucoma, ocular HTN, and in routine ocular examination. Want to thank TFD for its existence? Tell a friend about us, add a link to this page, add the site to iGoogle, or visit the webmaster's page for free fun content. |
