- Medical Definition of Tonometry. Tonometry: A standard eye test that is done to determine the fluid pressure inside the eye. Increased pressure is a possible sign of glaucoma, a common and potentially very serious problem if not detected and treated promptly. The pressure inside the eye is measured from the outside.

How Tonometry Eye Pressure Test Works The pressure that the cornea pushes back onto the tonometer is measured in millimeters of mercury, giving your eye doctor a number to record and compare to from year to year. Non-contact tonometry. Non-contact tonometry (NCT) is commonly referred to as the air puff test. Many people prefer this type of tonometry because it does not involve touching the eye. Instead, a gentle puff of air is used to flatten the cornea.

Trigonometry Trigonometry (from Greek trigōnon, triangle and metron, measure) is a branch of mathematics that studies relationships involving lengths and angles of triangles. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies.

Telemetry is the highly automated communications process by which measurements are made and other data collected at remote or inaccessible points and transmitted to receiving equipment for monitoring. The word is derived from Greek roots: tele = remote, and metron = measure. Systems that need external instructions and data to operate require the counterpart of telemetry, telecommand.

Trigonometry Then you'll love learning trigonometry! Trigonometry is a branch of math that looks at the relationships between side lengths of triangles and their corresponding angles. You'll be able to use your knowledge of geometry and algebra to derive and employ the trigonometric identities. Trigonometry is essential to the understanding of precalculus.

Stoichiometry and Balancing Reactions Stoichiometry is a section of chemistry that involves using relationships between reactants and/or products in a chemical reaction to determine desired quantitative data. In Greek, stoikhein means element and metron means measure, so stoichiometry literally translated means the measure of elements.

Ton The ton is a unit of measure. It has a long history and has acquired a number of meanings and uses over the years. It is used principally as a unit of mass. Its original use as a measurement of volume has continued in the capacity of cargo ships and in terms such as the freight ton.

Ocular tonometry Tonometry is the procedure eye care professionals perform to determine the intraocular pressure, the fluid pressure inside the eye. It is an important test in the evaluation of patients at risk from glaucoma. Most tonometers are calibrated to measure pressure in millimeters of mercury.

NON-CONTACT TONOMETRY NON-CONTACT TONOMETRY The non-contact tonometer is an applanation tonometer and works on the principle of a time interval. Measuring the time it takes from the initial generation of the puff of air to where the cornea is exactly flattened (in milliseconds) to the point where the timing device stops.

Glaucoma and Tonometry The Tono-Pen is a handheld device that’s shaped like a large marker. It provides a digital readout of eye pressure. Your doctor can use it to touch your eye and measure pressure. Though useful in many cases, the Tono-Pen is considered less accurate than the Goldmann tonometer in people with normal corneas.

Tonopen A handheld, compact, portable applanation tonometer based on the same principle as the Mackay-Marg tonometer. It is a very small instrument, 18 cm long by 2 cm in width weighing 56 g. It incorporates its own battery power supply and liquid crystal digital readout and provides both an intraocular pressure readout and an indicator of the reliability of the instrument.

What is complexometric titration? what is its application ? Report Abuse. Complexometric titration (sometimes chelatometry) is a form of volumetric analysis in which the formation of a colored complex is used to indicate the end point of a titration. Complexometric titrations are particularly useful for the determination of a mixture of different metal ions in solution.omplexometric titration (sometimes chelatometry) is a form of volumetric analysis in which the formation of a colored complex is used to indicate the end point of a titration.
