Tonometry is the measure of intraocular pressure. There are several methods used to obtain intraocular pressure, such as Goldmann applanation tonometry, Tono-Pen tonometry, pneumotonometry, and tactile tension. All these methods have advantages and disadvantages.

Self-tonometry with the Ocuton S versus Goldmann tonometry
Graefe's Archive for Clinical and Experimental Ophthalmology, 1999The purpose of the study was to evaluate the acceptance and reproducibility of a new self-tonometer (Ocuton S) and to compare it with the Goldmann applanation tonometer.The Ocuton S was studied in 20 healthy volunteers and 100 patients. After detailed explanation to each individual and a number of test measurements, we studied the reproducibility and ...

Respiration and arterial pulse cause intraocular pressure to cyclically vary around a mean pressure. Both the respiratory and arterial pulse waves approximate sine waves, and we have represented the IOP cycle as the sum of sinusoidal pressure waves. A rapidly acting tonometer may record any portion of the IOP cycle.

The cornea receives a slight amount of trauma from tonometry. This is more readily observed when fluorescein is used in the eye and examination is made with the aid of a slit lamp. At first, the subject appears to be one of rather academic interest, as there seems to be no excuse for inflicting injury on the cornea with the tonometer.

Noncontact Tonometry in Children
Optometry and Vision Science, 1991A hand-held noncontact tonometer (Pulsair, Keeler Ltd., UK) was tested in 42 children, from 5 months to 12 years of age. At least 1 intraocular pressure (IOP) reading was obtained in all of the 84 eyes studied, whereas with a Goldman applanation tonometer measurements could be obtained in only 26 eyes (14 subjects).

Airpuff tonometry versus applanation tonometry
Acta Ophthalmologica, 1990Abstract In order to study the reliability of airpuff tonometry, 230 eyes of 115 patients had their IOP measured with 2 airpuff tonometers, NCT and Pulsair, and one applanation tonometer, Perkins handheld Goldmann Type, between Dec 87 and March 89. Each patient had three readings per eye with each airpuff instrument and two readings per eye with the ...

Accommodation and Applanation Tonometry
Archives of Ophthalmology, 1961In a preceding publication, 1 the calculated C value of tonography was shown to be significantly affected by whether the eye, during tonography, was in the accommodated or relaxed state. The C values obtained during accommodation were significantly larger. Furthermore, attentive fixation of the "fixation-light" of the slit lamp for 4 min.
