Hole In Optic Nerve
The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the "copper" (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more
Visual cable: The optic nerve, the head of which is described in the back of the eye by your ophthalmologist as the disc, is the cable carrying visual information into the brain where it ends up in the occipital lobe and interpreted as vision. It contains over 1.2 million fibers as well as supporting elements. A truly amazing nerve.See 3 more doctor answers
Nerve swelling: Elevated optic nerve means one which which protrudes from the optic disc in back of the eye. This may developmental, or related to eye shape, or to swelling of optic nerve. Ask your ophthalmologist to explain these possibilities to you--it's part of his/her responsibility--i.e., education, instead of baffling you with medicalese.See 1 more doctor answer
Many causes: The optic nerve can be affected by trauma, infection, vascular occlusion, tumors in the optic canal or on the pituitary, or inflammatory processes like multiple sclerosis. If there is a sudden change in the vision, which is a hallmark of optic nerve dysfunction, see your ophthalmologist right away.
Birth defect: A few are born with significant maldevelopment (mostly loss) of an eye with loss also of the optic nerve. There are many with varying degrees of optic nerve dysfunction but they of course still have a nerve. An eye with no optic nerve would be totally blind.
Very stable: The optic nerve is a stable structure which does not spontaneously change. It can be affected by glaucoma, nervous system disease like MS and a variety of other conditions mostly uncommom.
Nonspecific: Hi! Lots of things to consider; what symptoms prompted you to get the scan? Any change in vision? Sinus pain or congestion? Bone pain elsewhere in your body? Headaches? Fever? I would definitely recommend close follow-up with a physician to do careful examination of your eyes and head/neck.
Usually nothing: Optic nerves, like other parts of our bodies, come in different sizes. If yours are congenitally large then that is how you were born and that is "normal" for you.
See eye doctor: See an eye doctor there is no information can be provided on line that will replace an evaluation by a physician and proper treatment
Not possible: A severed optic nerve will not re-establish functional communication with any currently known technique or medication. It is unfortunate but will have to wait for more advances in medical research.
No: Optic atrophy. If there is enlargement there is another disease process.
Lots of things: To start, etiologies include metabolic, autoimmune, vascular, infiltrative, neoplastic, traumatic, infectious, congenital, inflammatory, toxic agent, demyelinating and degenerative causes.
What does it mean if I have a tilted optic nerve? Can I fix it and are there any associated problems? Thanks.
Incomplete info: Without knowing what your symptoms are it is difficult to say whether you need any fixing. Also it is not clear what you mean by tilted optic nerve.
