Effects of Exercise on Ocular Parameters and Oxidative Stress Biomarkers in Saliva and Tear Fluid of Horses

open access: yesVeterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Submaximal exercise induced measurable oxidative responses in saliva and tear fluid of horses, while ocular parameters remained largely stable except for a mild reduction in tear secretion. Saliva and tear fluid may serve as practical, minimally invasive matrices for monitoring exercise‐associated physiological and oxidative responses in horses ...

Non-Invasive Ocular Rigidity Measurement: A Differential Tonometry Approach

open access: yesActa 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 ...

Ultrasound Biomicroscopic Evaluation of Postoperative Anterior Segment Changes in Canine Intumescent Cataracts

open access: yesVeterinary Ophthalmology, Volume 29, Issue 5, September 2026.
ABSTRACT Objective This study aimed to evaluate pre‐ and postoperative changes in the iridocorneal angle, ciliary cleft (CC), and ciliary muscle (CM) in canine eyes with intumescent cataracts using ultrasound biomicroscopy (UBM), with comparative reference to normal and non‐intumescent cataractous eyes.

The impact of central corneal thickness on values of intraocular pressure measured using two methods: Goldmann applanation and dynamic contour tonometry in patients with open-angle glaucoma [PDF]

open access: yesHalo 194, 2020
Introduction Dynamic contour tonometry (DCT) is a contact, non-applanation method for measuring intraocular pressure (IOP). Objektive The study aimed at evaluating the impact of central corneal thickness (CCT) on values of IOP measured using two methods:

Changes in intraocular pressure after intraocular eye surgery—the influence of measuring technique [PDF]

open access: yesInternational Journal of Ophthalmology, 2019
AIM: To investigate the changes in intraocular pressure (IOP) before and after intraocular surgery measured with Goldmann applanation tonometry (GAT) and pascal dynamic contour tonometry (PDCT), and assessed their agreement.

Cerebrovascular pulsatility following long duration spaceflight is associated with changes in pulse pressure and carotid artery stiffness

open access: yesExperimental Physiology, Volume 111, Issue 9, Page 4235-4247, 1 September 2026.
Abstract Central artery stiffening increases the haemodynamic pulsations transmitted downstream towards target organs, including the brain. While recent evidence suggests that long duration spaceflight is associated with reduced common carotid artery (CCA) distensibility, cerebrovascular pulsatility has not been extensively characterized in astronauts.

Obstructive Sleep Apnea: Epidemiology, Pathophysiology, Complications, Diagnosis, Management, and Emerging Fibrosis‐Linked Remodeling

open access: yesMedComm, Volume 7, Issue 8, August 2026.
Obstructive sleep apnea (OSA) is characterized by recurrent upper‐airway collapse, which generates key nocturnal stressors including intermittent hypoxia, sleep fragmentation, intrathoracic pressure stress, and sympathetic activation. These physiological disturbances converge on shared biological mechanisms, including oxidative stress, inflammation ...
