The Optic Nerve

Optic nerve ischemia: optic nerve sheath decompression alone or with optic nerve decompression.

Effect of scuba-diving on optic nerve and sheath diameters

  Background :There is not any data available about the effect of high bar pressure condition on intracranial pressure. In this study, the effect of diving on the optic nerve and sheath diameters as non-invasive markers of intracranial pressure has been investigated.   Methods : Twenty professional male divers from twenty one volunteers were chosen for this cross-sectional study. Only one perso...

Hypoplasia of the optic nerve.

Hypoplasia of the optic nerve is uncommon (Scheie and Adler, I94I; Somerville, I962; Whinery and Blodi, I963; Ewald, I967). It is usually due to a failure of development of the ganglion cell layer of the retina and results in a small but discernible optic disc with central vessels. The disc may be cupped with a peripapillary, mottled, yellowish halo corresponding to the size of the normal disc,...

P129: Use of Stem Cells to Regenerate Degenerative Optic Nerve

Stem cells are undifferentiated cells that have the ability to convert to different types of cells and after dividing, they can produce their own cells or other cells. Axons of the retinal ganglion cells, from the optic nerve. These cells lose the ability to regenerate themselves before birth. Optic nerve degeneration can result from various causes including increased intraocular pressure, comp...
