Take a mouse subjected to laser-induced damage to the optic nerve head in the eye.The damage causes endothelial cell injury and blood clot formation in the blood vessels supplying the nerve, reducing blood flow and causing ischemia.Ischemia deprives the retinal ganglion cell axons in the optic nerve head of oxygen.In the RGC cell bodies, this disruption impairs mitochondrial function and increases reactive oxygen species production.The resulting oxidative stress activates apoptotic signaling...

This article presents a protocol for nerve ultrasound in polyneuropathies to aid the diagnosis of inflammatory...

The following report describes how to replicate the rodent model of nonarteritic anterior ischemic optic neuropathy (rNAION), using the appropriate dye, contact lens and laser parameters. We also reveal the appropriate steps for evaluating the rNAION lesion in...

The goal of this protocol is to photochemically induce ischemic injury to the posterior optic nerve in rat. This model is critical to studies of the pathophysiology of posterior ischemic optic neuropathy, and therapeutic approaches for this and other optic neuropathies, as well as of other CNS ischemic...

Corneal Confocal microscopy is a non-invasive clinical technique which may be used to quantify C fibre damage to diagnose and stratify patients with increasing neuropathic...

This video demonstrates a method for establishing a small fiber neuropathy model in mice using the TRPV1 agonist resiniferatoxin (RTX). It outlines the steps involved in administering RTX to mice and explains how RTX induces neuronal death in small-diameter sensory neurons, thereby establishing the neuropathy...
