Optic Nerve Membrane
No recourse: A crushed optic nerve (how did this happen to you?) causes permanent changes which will alter the vision sometimes severely. There is currently no treatment known for this and a transplant is not possible. A discussion with a neuro-ophthalmologist would be helpful in this situation. ...Read more
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
Depends: On time, severity, etc. Specifically depends if the neurons have died (not recoverable at this time since an extension of the central nervous system) or are just in "distress" and could recover when the inflammation or inciting factor is resolved. Typically, not reversible to normal. ...Read moreSee 1 more doctor answer
Sometimes: Some optic nerve damage is reversible. For example, optic neuritis frequently recovers completely, when the cause is found and can be treated. Optic neuropathy due to vascular disease sometimes recovers. Traumatic injuries of the optic nerve may or may not recover. ...Read moreSee 1 more doctor answer
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. ...Read moreSee 3 more doctor answers
Slowly over time: Typically open angle glaucoma causes loss of ganglion cells with progressive thinning of the retinal nerve fiber layer faster than age-related loss slowly over time (thus generally asymptomatic), eventually leading to an enlarged optic nerve cup seen on eye exam. The optic nerve appears pale with loss of tissue and remodeled laminar changes. ...Read moreSee 1 more doctor answer
Not by itself: If an epiretinal membrane is the only pathology in the back of the eye, then the peripheral vision will be unaffected. Epiretinal membranes are commonly present in association with other retinal problems which may affect the peripheral vision although the membrane did not cause that. ...Read more
What's the difference between strabismus & cranial nerve palsies that effect the eyes? Can cranial nerve palsies cause strabismus?
Different patterns: Strabismus is the generic term for eye misalignment of any cause. If from childhood, the eyes are separated about the same in all positions. If from cranial palsy, the degree of separation goes from normal away from the action of the muscles, to a very wide difference in the direction of the action of that muscle. An ophthalmologist can usually readily make this distinction. ...Read more
Can vitrectomy for epiretinal membrane cause glaucoma to worsen. I currently have 25% optic nerve damage.
Low risk: There is some transient increase in pressure during the surgery, but this is usually tolerated well unless you have severe optic nerve damage. Also, epiretinal membrane surgery is fairly short in duration. Your doctor will also monitor your eye pressure while you are on steroid drops after the surgery as they can also make your eye pressure go up. Good luck. ...Read more
