Noun

tonometry - the measurement of intraocular pressure by determining the amount of force needed to make a slight indentation in the corneameasurement, measuring, mensuration, measure - the act or process of assigning numbers to phenomena according to a rule; "the measurements were carefully done"; "his mental measurings proved remarkably accurate"

Tonometry

the measurement of pressure—usually referring specifically to intraocular pressure. All tonometric methods are based on measurement of the eyeball’s capacity for deformation.

The approximate magnitude of intraocular pressure can be estimated by digital tonometry—the examiner making a subjective judgment of the degree of firmness of the eye by pressing it with the fingers. Greater accuracy in tonometry is achieved by the use of tonometers of varying design. Impression tonometry measures the degree of indentation of the eyeball produced by the tonometer rod and translates the reading into measures of intraocular pressure. Applanation tonometry measures the extent to which the eye can be flattened; the imprint (or tonogram) produced by a cylinder’s pressure on the eye is in the shape of a small circle, whose dimensions are converted into an index of pressure.

TONOMETRY: Measuring intraocular eye pressureThe measurement of tension of a part, as intraocular tension, used to detect glaucoma. See: illustration

analytical tonometry

A technique formerly used in blood gas analysis in which the liquid blood sample and its gas are held at equilibrium and the partial pressures of oxygen and carbon dioxide are measured.

applanation tonometry

Determining intraocular pressure by measuring the force necessary to flatten the corneal surface.

digital tonometry

Determining intraocular pressure by use of the fingers.

gastric tonometry

Measurement of the partial pressure of carbon dioxide (Pco₂) in the stomach of critically ill patients to determine how well the stomach and other internal organs are perfused with blood and oxygen. Poor gastric perfusion is found in more severe conditions, i.e., those that carry an increased risk of death.

noncontact tonometry

Determining intraocular pressure by measuring the degree of indentation of the cornea produced by a puff of air.

tonometry

Measurement of the pressure of the fluid within the eye.
