Optic Nerve Sheath Point of Care Ultrasound: Image Acquisition

Optic Nerve Sheath Point of Care Ultrasound: Image Acquisition

Point-of-care ultrasound (POCUS) of the optic nerve sheath diameter (ONSD) has been shown to be useful in identifying patients with increased intracranial pressure (ICP). However, the non-standardized technique for this POCUS has hampered its use. We present a standardized image acquisition protocol for use in the acute care...

Transconjunctival Approach for Injection into the Rat Optic Nerve

Transconjunctival Approach for Injection into the Rat Optic Nerve

This protocol describes a unique technique using a transconjunctival approach to access the rat optic nerve for injections.

Inducing Local Demyelination in the Optic Nerve Using Lysolecithin

Inducing Local Demyelination in the Optic Nerve Using Lysolecithin

This video demonstrates the procedure of surgically accessing the optic nerve in an anesthetized animal and precisely delivering lysolecithin to induce focal demyelination, creating neuropathological conditions for further...

A Surgical Approach for Optic Nerve Crush in a Rabbit Model

This paper presents detailed instructions to perform optic nerve crush in a rabbit model using standard ophthalmic surgical techniques.

Optic Nerve Transection: A Model of Adult Neuron Apoptosis in the Central Nervous System

Optic Nerve Transection: A Model of Adult Neuron Apoptosis in the Central Nervous System

Optic Nerve transection is a widely used model of adult CNS injury. Ninety percent of retinal ganglion cells (RGCs) whose axons are completely transected (axotomy) die within 14 days after axotomy. This model is easily amenable to experimental manipulations and highly...

Minimally-invasive Technique for Injection into Rat Optic Nerve

Minimally-invasive Technique for Injection into Rat Optic Nerve

Direct injection into the rat optic nerve is useful for regenerative research. We demonstrate a minimally-invasive technique for direct injection into a rat optic nerve that does not involve opening the skull. Using this method, surgical complications are minimized and recovery is more rapid.
