Intravitreal Triamcinolone Acetonide Injection in a Rodent Model of Anterior Ischemic Optic Neuropathy: Comment

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...

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...

Intravitreous injection is a widely used technique in visual sciences research for ocular diseases or as direct application of local treatment. This video demonstrated a protocol for intravitreous injection using a 1ml syringe with glass pipette. Useful tips about avoiding massive bleeding and lens damage are...

Intravitreal injections were performed in the sheep eye with the aim of delivering viral-mediated gene therapy to the...

This protocol outlines the steps for inducing myocardial infarction in mice while preserving the pericardium and its...
