Dynamic contour tonometry in corneal oedema

Acta Ophthalmologica Scandinavica, 2007
Abstract Purpose: Tonometry in corneal oedema is a current problem. In clinical routine intraocular pressure (IOP) may be measured erroneously too low in edematous thickened cornea using Goldmann applanation tonometry.To compare Goldmann applanation tonometry (GAT) and dynamic contour tonometry (DCT, Pascal, Technomed, Germany) in postsurgical corneal ...

Dynamic contour tonometry versus Goldmann applanation tonometry: challenging the gold standard [PDF]

Expert Review of Ophthalmology, 2010
The accurate measurement of intraocular pressure (IOP) is fundamental to almost any ophthalmic examination. Dynamic contour tonometry (DCT) was introduced 5 years ago as an entirely novel contact tonometry principle designed to measure IOP largely independently of corneal properties.

Wearable Technology and Its Potential Role in Cardiovascular Health Monitoring and Disease Management

Health Science Reports, Volume 8, Issue 11, November 2025.
ABSTRACT Background Cardiovascular disease (CVD) remains the foremost cause of death globally, accounting for approximately 17.9 million deaths in 2019, 32% of all global fatalities with myocardial infarction and stroke constituting 85% of these. The disproportionate burden in low‐ and middle‐income countries underscores the urgent need for scalable ...

Non-Invasive Ocular Rigidity Measurement: A Differential Tonometry Approach

Acta Medica, 2015
Purpose: Taking into account the fact that Goldmann applanation tonometry (GAT) geometrically deforms the corneal apex and displaces volume from the anterior segment whereas Dynamic Contour Tonometry (DCT) does not, we aimed at developing an algorithm ...

Non-invasive Clinical Measurement of Ocular Rigidity and Comparison to Biomechanical and Morphological Parameters in Glaucomatous and Healthy Subjects

Frontiers in Medicine, 2021
Purpose: To assess ocular rigidity using dynamic optical coherence tomography (OCT) videos in glaucomatous and healthy subjects, and to evaluate how ocular rigidity correlates with biomechanical and morphological characteristics of the human eye.Methods:

Bridging competence and practice: The role of Entrustable Professional Activities (EPAs) in optometric education

Ophthalmic and Physiological Optics, Volume 45, Issue 7, Page 2063-2071, November 2025.
Abstract Background Competency‐based education (CBE) has gained prominence in health profession education, emphasising the assessment of learners based on their ability to perform essential tasks in clinical practice. Entrustable Professional Activities (EPAs) operationalise competency assessment by translating broad competencies into specific tasks ...

Acute live firefighting effects on ventricular‐arterial coupling and pulsatile afterload in middle‐aged firefighters

Physiological Reports, Volume 13, Issue 22, November 2025.
Abstract Firefighting increases afterload, leading to ventricular‐arterial coupling mismatch in young firefighters that may contribute to coronary hypoperfusion and the elevated risk of on‐duty cardiac events. Since this risk is higher with aging in firefighters, we examined their ventricular‐vascular coupling and afterload responses to acute ...

Artifact management methodologies for arterial blood pressure signals: A systematic scoping review of human and animal literature

Physiological Reports, Volume 13, Issue 19, October 2025.
Abstract Arterial blood pressure (ABP) is a broadly measured vital signal used to monitor cardiovascular health through raw signal and derived metrics. Artifacts are a pervasive issue, resulting in a declined utility of the signal. The aim of this review was to examine the existing literature pertinent to artifact management strategies in ABP signals ...

Arterial stiffness moderates the link between NfL and cognition: The IGNITE study

Alzheimer's &Dementia, Volume 21, Issue 8, August 2025.
Abstract INTRODUCTION Arterial stiffness (carotid‐femoral pulse wave velocity [cfPWV]) and plasma neurofilament light (NfL), markers of vascular and neuroaxonal aging, are linked to cognitive decline. Whether higher cfPWV amplifies the NfL–cognition relationship remains unclear.
