The optic nerve is composed of retinal ganglion cell axons and glia. Each human optic nerve contains between 770,000 and 1.7 million nerve fibers, which are axons of the retinal ganglion cells of one retina.
Aug 16, 2023 · The optic nerve head is a unique part of CN II in that it marks an important point of vascular, geometric and tonometric transition. At the optic nerve head, the optic nerves are moving to the relatively low pressure space of the retro-orbital region from the much higher intraocular pressure zone.
May 27, 2023 · Anatomy. The optic nerve is mainly made up of the axons (nerve fibers) of the retinal ganglion cells from the retina. The optic disc or nerve head is the point where the axons from the retinal ganglion cells leave the eye. The nerve head appears as a white circular structure in the back of the eye. There are no photoreceptors on this structure.
Mar 28, 2024 · Optic Nerve Photos and Scans. Two common imaging tests include a simple high-resolution color photograph with a very bright flash from a professional camera, and a quick laser scan of the optic nerve. Scans can detect small nerve fiber layer changes of the optic nerve at the micron level.
This article will discuss information on evaluation of the intra-bulbar structure of the optic nerve as it relates to glaucoma, with particular emphasis on three imaging devices, confocal scanning laser ophthalmoscopy, optical coherence tomography, and scanning laser polarimetry. Optic Nerve Anatomy.
May 27, 2024 · The optic nerve is the second ( CN II ) cranial nerve ( TA: nervus opticus or nervus cranialis II). It is a purely sensory nerve that conveys visual information from the eye to the brain . The nerve arises from the back of the globe exiting the orbit via the optic canal.
