Optic Nerve Damage Reversible
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
A complete nerve transection will leave an area totally numb. The distribution of the numbers depends upon where the nerve was cut. A partial nerve injury may leave the area tingly or incompletely numb. Finally even if the nerve is not cut the swelling and bruising to the tea can affect the nerve as well. Usually we consider sharp penetrating injuries as likely having nerve lacerations when sensation is lost. A hand surgeon can examine the hand and pinpoint the site or extent of nerve injury and recommend ...Read more
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

Processing: Vision is from the brain. The retina can send messages through the optic nerve to the occipital lobe. But once they get there, no vision occurs unless the brain processes the messages. This processing may vary. Help him to find the right setting to allow the best processing. ...Read more

Glaucoma: Glaucoma is a condition where the optic nerve can not withstand the pressure within the eye. If it is determined that you have optic nerve damage and it is due to pressure, then you have glaucoma. You need to treat (or lower the pressure) to a point where no more damage occurs to prevent further damage and vision loss. ...Read moreSee 1 more doctor answer
No loss of function : Minimal optic nerve damage seen in early glaucoma is a structural change with or without visual field loss, depending on how the nerve is structurally changed. A visual field defect therefore isn't necessary to have in early glaucoma. Minimal nerve damage may show up as asymmetry, cup elongation, nerve fiber layer thinning, focal notching or excavation, vessel deformation, and other. ...Read more
Neuropraxia is defined as a temporary loss of function of the nerve. Some nerves are purely sensory while others carry both sensory and motor fibers. Traumatic contusion injuries to nerves or nerve compressions can cause Neuropraxia. Sensory nerves like sural nerve in the leg or mixed sensory and motor nerves like the median and ulnar nerves in the forearm & hand ...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
