Optic nerve as a source of activated retinal microglia post-injury

Acta Neuropathologica Communications, 2018
Using mice expressing green fluorescent protein (GFP) from a transgenic CD11c promoter we found that a controlled optic nerve crush (ONC) injury attracted GFPhi retinal myeloid cells to the dying retinal ganglion cells and their axons.

Ischemic optic neuropathies: Current concepts

Annals of Indian Academy of Neurology, 2022
Ischemic optic neuropathy (ION) is the term ascribed to optic nerve disease that is the result of a transient or permanent interruption of the blood supply to any portion of the optic nerve. Anterior ischemic optic neuropathy (AION) refers to ischemia of

The impact of optic nerve movement on optic nerve magnetic resonance diffusion parameters

South African Journal of Radiology, 2014
Background: Optic nerve diffusion imaging is a useful investigational tool of optic nerve microstructure, but is limited by eye-movement-induced optic nerve movement and artifacts from surrounding cerebrospinal fluid, fat, bone and air.
