What is the Real Cause of Glaucoma? [PDF]

Iranian Journal of Medical Physics, 2010
Introduction: The term glaucoma refers to a group of diseases that have a characteristic optic neuropathy with associated visual field loss in common. Intraocular pressure has been considered to be the only causal factor for glaucoma and the only factor ...

Future Research Perspective on the Interfacial Physics of Non-Invasive Glaucoma Testing in Pathogen Transmission from the Eyes [PDF]

arXiv, 2023
Non-contact Tonometry (NCT) is a non-invasive ophthalmologic technique to measure intraocular pressure (IOP) using an air puff for routine glaucoma testing. Although IOP measurement using NCT has been perfected over many years, various phenomenological aspects of interfacial physics, fluid structure interaction, waves on corneal surface, and pathogen ...

Stress induced aging in mouse eye

Aging Cell, Volume 21, Issue 12, December 2022., 2022
Skowronska‐Krawczyk and colleagues describe the transcriptional and epigenetic changes happening in aging retina. They also show that upon stress such as intraocular pressure elevation in the eye, retinal tissue undergoes epigenetic and transcriptional changes similar to natural aging.

Change in Intraocular Pressure During Point-of-Care Ultrasound

Western Journal of Emergency Medicine, 2015
Introduction: Point-of-care ocular ultrasound (US) is a valuable tool for the evaluation of traumatic ocular injuries. Conventionally, any maneuver that may increase intraocular pressure (IOP) is relatively contraindicated in the setting of globe rupture.

Nearly-incompressible transverse isotropy (NITI) of cornea elasticity: model and experiments with acoustic micro-tapping OCE [PDF]

arXiv, 2020
The cornea provides the largest refractive power for the human visual system. Its stiffness, along with intraocular pressure (IOP), are linked to several pathologies, including keratoconus and glaucoma. Although mechanical tests can quantify corneal elasticity ex vivo, they cannot be used clinically. Optical coherence elastography (OCE), which launches

Identifying factors associated with fast visual field progression in patients with ocular hypertension based on unsupervised machine learning [PDF]

arXiv, 2023
Purpose: To identify ocular hypertension (OHT) subtypes with different trends of visual field (VF) progression based on unsupervised machine learning and to discover factors associated with fast VF progression. Participants: A total of 3133 eyes of 1568 ocular hypertension treatment study (OHTS) participants with at least five follow-up VF tests were ...

The NLRP3 inflammasome pathway contributes to chronic inflammation in experimental autoimmune uveitis

Animal Models and Experimental Medicine, EarlyView.
The present study investigates the role of the NLRP3 inflammasome in the chronicity of ocular inflammation in uveitis using the experimental autoimmune uveitis (EAU) model. Whole eyes collected from EAU mice, 12 weeks post induction, were sectioned and subjected to immunohistochemistry. The confocal images from these sections were then assessed for the
