A Comparison of Wearable Tonometry, Photoplethysmography, and Electrocardiography for Cuffless Measurement of Blood Pressure in an Ambulatory Setting

IEEE journal of biomedical and health informatics, 2022
Objective: While non-invasive, cuffless blood pressure (BP) measurement has demonstrated relevancy in controlled environments, ambulatory measurement is important for hypertension diagnosis and control. We present both in-lab and ambulatory BP estimation

Meta-analysis of the concordance of Icare® PRO–based rebound and Goldmann applanation tonometry in glaucoma patients

European Journal of Ophthalmology, 2020
Background: The Icare® PRO rebound tonometer is being promoted as a patient-friendly device for glaucoma detection and monitoring, allowing rapid and accurate intraocular pressure measurement avoiding anaesthesia. The aim of this systematic review was to

[Current state of ophthalmic tonometry].

Vestnik oftal mologii, 2020
Currently, the level of intraocular pressure (IOP) can be assessed with a large number of tonometers, which differ in the principle of action, the place of application and the degree of invasiveness. All the methods in use - except for direct manometry -

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.

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.

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 ...

Comparison of the SphygmoCor XCEL device with applanation tonometry for pulse wave velocity and central blood pressure assessment in youth

Journal of Hypertension, 2018
Background: Vascular phenotype by assessing carotid–femoral pulse wave velocity (cf-PWV) and central SBP (cSP) in the young could be used as an intermediate cardiovascular outcome measure.

Self-tonometry with the Ocuton S versus Goldmann tonometry

Graefe's Archive for Clinical and Experimental Ophthalmology, 1999
The 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 ...

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 ...
