A new tonometer based on the application of micro-mechanical sensors [PDF]
, 1993 An instrument for the measurement of intraocular pressure (IOP) is presented. It consists of a micromachined silicon sensor, which measures the diameter of a flattened part of the eye globe and simultaneously determines the smallest distance between the ...

Effect Of Mirthful Laughter On Vascular Function [PDF]
, 2010 In contrast to the well-established scientific evidence linking negative emotional states (e.g., depression, anxiety, or anger) to increased risk for cardiovascular disease, much less is known about the association between positive emotional states (e.g.,

Corneal astigmatism in applanation tonometry [PDF]
Eye, 2003 This short study aims at quantitatively correlating scale readings of the Goldmann tonometer to corneal curvatures in one and the same eye.A total of 30 eyes of 21 adult patients who presented themselves in clinical practice for routine examination were arbitrarily selected.

On the Validity of the Imbert-Fick Law: Mathematical Modelling of Eye Pressure Measurement [PDF]
, 2016 YesOphthalmologists rely on a device known as the Goldmann applanation tonometer to make intraocular pressure (IOP) measurements. It measures the force required to press a flat disc against the cornea to produce a flattened circular region of known ...

Association between one-hour post-load plasma glucose levels and vascular stiffness in essential hypertension [PDF]
, 2012 Objectives: Pulse wave velocity (PWV) is a surrogate end-point for cardiovascular morbidity and mortality. A plasma glucose value $155 mg/dl for the 1-hour post-load plasma glucose during an oral glucose tolerance test (OGTT) is able to identify ...
