Optic Nerve
Research News and Information
Definition of 'Optic Nerve'The 2nd cranial nerve. The optic nerve conveys visual information from the retina to the brain. The nerve carries the axons of the retinal ganglion cells which sort at the optic chiasm and continue via the optic tracts to the brain. The largest projection is to the lateral geniculate nuclei; other important targets include the superior colliculi and the suprachiasmatic nuclei. Though known as the second cranial nerve, it is considered part of the central nervous system. |

[Ocular signs of increased intracranial pressure]
25 Sep 2009 
Ocular signs developing as a result of increased intracranial pressure help the early diagnosis and prevention of severe and progressive pathological processes. Functional signs of the forming papillary oedema and central eye movement disorders may ... Read more...
30 Aug 2009 PURPOSE: To compare the effects of latanoprost/timolol (LTFC) versus dorzolamide/timolol (DTFC) fixed combinations on intraocular pressure (IOP), visual function, and retrobulbar blood flow in patients with open-angle glaucoma (OAG). METHODS: This ... Read more...
The morphology and spatial arrangement of astrocytes in the optic nerve head of the mouse.
30 Aug 2009 We evaluated the shapes, numbers, and spatial distribution of astrocytes within the glial lamina, an astrocyte-rich region at the junction of the retina and optic nerve. A primary aim was to determine how the population of astrocytes, collectively, ... Read more...
