The tonometric sensor, a new device for the measurement of intraocular pressure [PDF]

open access: yes, 1989
In this paper we present a new sensor for the measurement of intraocular pressure. We have applied the indentation principle, in which the eye is indented by exerting a force on it, while the size of the indented area is monitored.

Modeling and FEM-based Simulations of Composite Membrane based Circular Capacitive Pressure Sensor [PDF]

open access: yesarXiv, 2019
In Micro-electro-mechanical Systems (MEMS) based pressure sensors and acoustic devices, deflection of a membrane is utilized for pressure or sound measurements. Due to advantages of capacitive pressure sensor over piezoresistive pressure sensors (low power consumption, less sensitive to temperature drift, higher dynamic range, high sensitivity ...

A numerical model of the human cornea accounting for the fiber-distributed collagen microstructure [PDF]

open access: yesarXiv, 2023
We present a fiber-distributed model of the reinforcing collagen of the human cornea. The model describes the basic connections between the components of the tissue by defining an elementary block (cell) and upscaling it to the physical size of the cornea.

Costello Syndrome and Ophthalmologic Issues: Unveiling the Unseen

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Costello syndrome (CS) is an ultra‐rare condition belonging to the RASopathies, a group of disorders characterized by aberrant RAS/MAPK pathway signaling, which is involved in ocular development and in some eye pathologies. However, only a few studies assessing the ophthalmic features of individuals with CS are available.

Change in Intraocular Pressure During Point-of-Care Ultrasound

open access: yesWestern 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.

Intraocular pressure reduction and regulation system [PDF]

open access: yes
An intraocular pressure reduction and regulation system is described and data are presented covering performance in: (1) reducing intraocular pressure to a preselected value, (2) maintaining a set minimum intraocular pressure, and (3) reducing the ...

ARHGEF12 influences the risk of glaucoma by increasing intraocular pressure.

open access: yesHuman Molecular Genetics, 2015
Primary open-angle glaucoma (POAG) is a blinding disease. Two important risk factors for this disease are a positive family history and elevated intraocular pressure (IOP), which is also highly heritable.
