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.

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 ...

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 ...

ANATOMO-TOPOGRAPHIC AND HYDRODYNAMIC PARAMETERS OF THE EYE AFTER CATARACT PHACOEMULSIFICATION
Alʹmanah Kliničeskoj Mediciny, 2016 Background: Removal of the native lens alters spatial relationships between anterior eyeball structures and results in fluctuations in intraocular pressure. Intraocular pressure control is important for the prevention of early postoperative complications.

Device for ECG prediction based on retinal vasculature analysis [PDF]
arXiv, 2020 Pulsatile changes in retinal vascular geometry over the cardiac cycle have clinical implications for the diagnosis of ocular and systemic vascular diseases, including ischemia, coronary heart diseases, and diabetes mellitus and its complications. Thus, analysis of the pulsatile changes over the cardiac cycle is a potential non-invasive assessment for ...
