The Biomechanics of Indirect Traumatic Optic Neuropathy Using a Computational Head Model With a Biofidelic Orbit

Frontiers in Neurology, 2020
Indirect traumatic optic neuropathy (ITON) is an injury to the optic nerve due to head trauma and usually results in partial or complete loss of vision. In order to advance a mechanistic understanding of the injury to the optic nerve, we developed a head

NRF2 Deficiency Disrupts Mitochondrial Homeostasis via NDUFS7 in Trabecular Meshwork

Research
The trabecular meshwork (TM) plays a pivotal role in maintaining intraocular pressure (IOP) by regulating aqueous humor outflow. Nuclear factor erythroid 2-related factor 2 (NRF2) was identified as a key transcriptional controller of TM redox balance and

Mechanical activation of PIEZO1 drives AP-1–dependent PTGS2/PGE2 signaling and corneal inflammation

iScience
Summary: Abnormal mechanical stimulation, such as eye rubbing, is a critical risk factor for corneal diseases, yet the molecular mechanisms linking mechanical stimulation to inflammation remain unclear.

Low-Field Magnetic Resonance Imaging Findings in 18 Dogs With Presumed Optic Neuritis

Frontiers in Veterinary Science, 2021
Canine optic neuritis has been attributed to a focal or disseminated form of granulomatous meningoencephalitis (GME) amongst other etiologies. Magnetic resonance imaging (MRI) has been proven to help differentiate the structures within the optic nerve ...
