Airpuff tonometry versus applanation tonometry

Acta Ophthalmologica, 1990
Abstract 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 ...

Tonometry

Insight - the Journal of the American Society of Ophthalmic Registered Nurses, 1998
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.

Equine Tonometry

Journal of the American Veterinary Medical Association, 1970
SUMMARY Indirect intraocular tonometry was performed on 6 horses, using an electronic tonometer,” with a topical anesthetic and a tranquilizer. Mean indirect intraocular pressure for these horses was 24.5 mm. Hg (S.D. = 4.0). Direct and indirect intraocular pressure values were also simultaneously recorded on 6 horses under general anesthesia and on 3 ...

Instantaneous Tonometry

Archives of Ophthalmology, 1983
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.

Tonometry and the Cornea

Archives of Ophthalmology, 1956
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.

Accommodation and Applanation Tonometry

Archives of Ophthalmology, 1961
In 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.
