Neurotrophic Signaling, Sleep Physiology, and Retinal Neuroprotection: Integrative Mechanisms and Therapeutic Implications for Glaucoma

Sensory Neuroscience, EarlyView.
Glaucoma is increasingly understood as a neurodegenerative disorder shaped by sleep and circadian physiology, not intraocular pressure alone. Sleep loss and obstructive sleep apnea suppress BDNF–TrkB neurotrophic signaling, impair sleep‐dependent glymphatic clearance, and trigger microglial neuroinflammation and vascular insult at the optic nerve head,

Longitudinal changes in bleb morphology following the PAUL Glaucoma Implant visualized using ultrasonography

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate bleb morphology longitudinally using sonography following glaucoma drainage device (GDD) surgery. Methods Prospective observational cohort study conducted from January 2022 to March 2024, with follow‐up up to 12 months postoperatively. Bleb morphology, including superior and inferior bleb height, transverse and longitudinal

Australian and New Zealand Glaucoma Society (ANZGS) Consensus on Interventional Glaucoma

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background Traditional reactive ‘wait and see’ approaches in glaucoma management often result in unacceptable rates of permanent vision loss. This consensus defines a proactive ‘interventional glaucoma’ framework tailored for the Australian and New Zealand healthcare context. Methods A modified Delphi consensus process was utilised, consisting

Reduced order modelling of air‐puff test for corneal material characterisation

Journal of Microscopy, EarlyView.
Abstract Models of the fluid–structure interaction (FSI) model for the air‐puff test were analysed. Using Abaqus, the air‐puff test is applied to eyes with varying biomechanical parameters, such as material properties, corneal thickness, and radius.

Review on Dynamic Contour Tonometry and Ocular Pulse Amplitude [PDF]

Ophthalmic Research, 2015
Intraocular pressure (IOP) measurement is the cornerstone of the management of glaucoma patients. The gold standard for assessing IOP is Goldmann applanation tonometry (GAT). Recently, the dynamic contour tonometer (DCT) has become available. While both devices provide reliable IOP measurements, the results are not interchangeable.

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 ...

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.

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 ...

Ultrafast fMRI Detects Age‐Related Changes in Harmonics of Cardiac Pulsations in the Brain at 7 T

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1206-1218, September 2026.
ABSTRACT Purpose Aging impacts pulsatility of blood vessels in the brain, reflecting vascular health. Resolving characteristics of cardiac pulsatility requires faster acquisitions than traditional fMRI. An ultrafast fMRI method was developed and applied to sample several harmonics of cardiac pulsations at 7 T.
