tonometer
Noun: 1. A medical instrument for measuring pressure, specifically intraocular pressure: A tonometer is a device used primarily in ophthalmology to measure the pressure inside the eye, which is a key test for detecting conditions like glaucoma. 2. A measuring instrument for tension or pressure in a general sense: In broader technical contexts, it can refer to any instrument designed to measure tension or pressure.
- Noun (Medical):
- The doctor used a tonometer to check for signs of glaucoma during my eye exam.
- Regular tonometer readings are essential for monitoring eye health.
- Noun (General):
- In physics lab, we used a specialized tonometer to measure the surface tension of the liquid.
- "Applanation tonometer": A specific type of tonometer that measures intraocular pressure by flattening a small area of the cornea.
- Goldmann applanation tonometry is considered the gold standard for measuring intraocular pressure.
- "Rebound tonometer": A portable, often handheld, device that measures pressure by bouncing a small probe off the cornea.
- The rebound tonometer is useful for screening patients who cannot be examined at a slit lamp.
- Tonometry (n): The process or act of measuring pressure, especially intraocular pressure, with a tonometer.
- Tonometry is a routine part of a comprehensive eye examination.
- Tonometric (adj): Relating to or involving a tonometer or tonometry.
- The tonometric data was recorded for the patient's file.
- Pressure gauge: An instrument for measuring pressure (general synonym).
- Manometer: An instrument for measuring the pressure of gases or liquids (specific to fluid pressure).
(Note: As a technical noun, "tonometer" does not form standard phrasal verbs. Its usage is primarily in noun phrases.) - To perform tonometry: To carry out a pressure measurement, especially on the eye. - The technician was trained to perform tonometry accurately.
(Note: As a highly specialized technical term, "tonometer" is not commonly used in idiomatic expressions.)
- measuring instrument for measuring tension or pressure (especially for measuring intraocular pressure in testing for glaucoma)
