The Effects of Trabeculectomy on Ocular Pulse Amplitude in Patients with Glaucoma

Beyoglu Eye Journal, 2019
INTRODUCTION[|]This study aimed to investigate whether trabeculectomy and its intraocular pressure (IOP)-lowering effect have an effect on ocular pulse amplitude (OPA) in glaucoma patients.[¤]METHODS[|]Thirty-five consecutive patients with glaucoma (70 ...

Beyond the Ocular Surface: Nasal Sensory Input as a Driver of Reflex Lacrimation in Dogs

Veterinary Ophthalmology, EarlyView.
ABSTRACT Objective To evaluate the effect of nasal mucosal anesthesia on aqueous tear secretion in dogs and to compare responses between brachycephalic and non‐brachycephalic breeds. Animal Studied Twenty healthy dogs (10 Australian Shepherds, 10 Boston Terriers). Procedures All dogs received 0.5 mL of 10% lidocaine or saline into one randomly selected

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

Experimental Physiology, EarlyView.
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.

Utility of Goldmann applanation tonometry for monitoring intraocular pressure in glaucoma patients with a history of laser refractive surgery. [PDF]

PLoS ONE, 2018
The utility of Goldmann applanation tonometry (GAT) for monitoring intraocular pressure (IOP) in open-angle glaucoma (OAG) patients with a history of laser refractive surgery was investigated by comparing IOP fluctuations measured using GAT and dynamic ...

Intraocular Pressure Increase Induced by 0.5% Tropicamide‐0.5% Phenylephrine in Dogs: An Analysis of Causes Using Ultrasound Biomicroscopy

Veterinary Ophthalmology, Volume 29, Issue 1, January 2026.
ABSTRACT Purpose To determine whether the differences in intraocular pressure (IOP) change after the topical application of 0.5% tropicamide and 0.5% phenylephrine (TP) are due to anatomical variations in the anterior chamber using ultrasound biomicroscopy (UBM).

Integrative cardiovascular dose–response to graded lower‐body negative pressure

Experimental Physiology, Volume 110, Issue 12, Page 1852-1879, December 1, 2025.
ABSTRACT Lower‐body negative pressure (LBNP) has been posited as a potential spaceflight countermeasure to counteract the physiological deconditioning related to fluid shifts in microgravity. However, open questions remain regarding the magnitude of LBNP that should be applied.
