Non-invasive medical diagnostics demonstrate a propensity for droplet generation and should be studied to devise risk mitigation strategies against the spread of SARS-CoV-2 virus. We investigate air-puff tonometry, which uses short-timed applanate human eye in bid detect early onset glaucoma by measuring intraocular pressure. The consists vortex trailed high-speed jet. High-speed imaging during...

ABSTRACT The objective of this study was to establish ophthalmic parameters in the Pomeranian dog breed. Schirmer tear test (STT), breakup time (TBUTT), Jones (JT), aesthesiometry, biomicroscopy, tonometry, non-contact specular microscopy (SM), ophthalmoscopy and ultrasonography (US) were carried out 48 eyes 24 male female dogs from a breeding kennel. Descriptive statistics applied for data ana...

THE Goldmann applanation tonometer (1954), as modified by Goldmann and Schmidt (1957), is becoming the standard instrument for measuring the intra-ocular pressure. The accepted method of preparing the eye for a pressure reading is to anaesthetize the cornea and then to stain the pre-corneal film with fluorescein (DukeElder, 1962). The disadvantage of this method is that it requires two manceuvr...

Inflammation causes vascular dysfunction and perpetuates proatherosclerotic processes. We hypothesized that a broad panel of inflammatory biomarkers and single nucleotide polymorphisms in inflammatory genes is associated with vascular stiffness. We assessed 12 circulating inflammatory biomarkers (C-reactive protein, fibrinogen, interleukin-6, intercellular adhesion molecule-1, lipoprotein-assoc...

Intraocular pressure (IOP) remains the only modifiable risk factor in the management of glaucoma. Hence, IOP and its appropriate measurement deserve our ongoing interest. Over the years, not only has our understanding of glaucoma changed but also has changed our approach to the measurement of the IOP. This review is an attempt to elucidate the commonly techniques of tonometry, and critically ev...

The ABL 500 blood gas analyser from Radiometer has cordless electrodes and does not use a humidifier for calibrating gases. During the evaluation of the analytical performance of this instrument, the problem of p0(2) accuracy was approached by comparing the values obtained with two kinds of tonometry (film and bubble). An acceptable level of imprecision was demonstrated for all measured paramet...

BACKGROUND AND PURPOSE Previous work from the Framingham Heart Study suggests that brain changes because of arterial aging may begin in young adulthood and that such changes precede cognitive deficits. The objective of this study was to determine the association of arterial stiffness with measures of white matter and gray matter (GM) integrity in young adults. METHODS One thousand nine hundre...

INTRODUCTION The occurrence of organ failure following thermal injury, despite restoration of hemodynamic parameters and urine output during resuscitation, has led to efforts to measure end-organ perfusion. The purpose of this 24-h study was to evaluate the utility of gastrointestinal (GI) tonometry during burn shock and resuscitation. METHODS Male swine (n=11, 23.3+/-0.9 kg) were anesthetize...

Aging is associated with increased central aortic systolic pressure (CSP) and pulse pressure which are predictive of cardiovascular events. Mechanisms implicated for higher central pressures include a higher forward incident pressure wave (P1), higher augmented pressure (AP), and shorter reflected wave round trip travel time (Tr). African-Americans (AA) have more frequent and deleterious blood ...
