Optic nerve swelling due to inflammation is called optic neuritis. Optic neuritis may be the first sign of an autoimmune disease, such as multiple sclerosis. It can also be caused by certain infections, including measles, mumps, chicken pox, shingles, Lyme disease, cat scratch fever, meningitis and syphilis.
Problems with blood vessels that can cause optic nerve damage. Certain types of diseases or conditions of blood vessels can cause optic nerve damage including: Anterior ischemic optic neuropathy (stroke of the eye caused by diminished blood flow to the arteries that supply blood to the optic nerve). Blood clot that obstructs an artery that supplies blood to the optic nerve. Cerebral aneurysm (life-threatening bulging and weakening of the wall of an artery that can burst and cause severe hemorrhage). Stroke. Subarachnoid hemorrhage (type of bleeding around the brain).
