A stroke of the optic nerve is caused by ischemia or poor circulation to the blood vessels that supply the front or anterior portion of the optic nerve. Without nutrients and oxygen being supplied in adequate amounts, a portion of the nerve tissue will be lost.isual acuity is directly related to the location and amount of the optic nerve affected by the stroke. Some patients may have a profound loss in one eye while the other eye still has 20/25 vision. However, loss of side vision often complicates the loss of vision.
1 Damage to the optic tract, which is behind (posterior) to the chiasm, causes loss of the entire visual field from the side opposite the damage (so if the left optic track is cut, there is a loss of vision from the entire right visual field).s a consequence, the fibers of the optic nerve are covered with myelin produced by oligodendrocytes, rather than Schwann cells of the peripheral nervous system, and are encased within the meninges. Peripheral neuropathies like Guillain-Barre barrÃ© syndrome do not affect the optic. nerve
