Is optic nerve damage reversible?

Is optic nerve damage reversible?

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 more

Nerve Damage (Definition)

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

Optic nerve damage reversible?

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 more

My husband has optic nerve damage one day he can see ok and the next he can't he wants to know why his eyesight flutuates with this damage?

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

What should I know about glaucoma and optic nerve damage?

What should I know about glaucoma and optic nerve damage?

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 more

In early glaucoma what would be considered minimal optic nerve damage?

In early glaucoma what would be considered minimal optic nerve damage?

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

For glaucoma to be caught early does that mean there must be no optic nerve damage?

For  glaucoma to be caught early does that mean there must be no optic nerve damage?

Not necessarily...: Glaucoma is the 'sneak thief of sight' and usually causes damage that occurs gradually but permanently. It's important that people at risk come in for regular exams so it can be diagnosed, and the damage 'nipped in the bud'. There can be some nerve damage incurred by the time glaucoma is caught relatively early, but the good news is the patient won't likely notice that their vision is affected. ...Read more

Can color changes in vision mean optic nerve damage ?? Or retina damage ? Can being under too much light cause this I'm really scared

Can color changes in vision mean optic nerve damage ?? Or retina damage ? Can  being under too much light cause this I'm really scared

See Opthomologist!: There are too many possibilities to review in 400 words. Yes, optic nerve changes can create color changes.....but.....so can rapid changes of blood sugar (seen in diabetes) or certain forms of thyroid conditions with eyeball involvement. Certain chemicals as well as drugs can result in color vision changes. You should call your Family MD to help you get a visit with an Opthomologist (eye Doctor). ...Read more

Oct shows nerve tissue thinning. No visual field loss. 1 dr. Said 30% optic nerve damage & 2 others say not that much. Can percentage be relied on?

Oct shows nerve  tissue thinning. No visual field loss. 1 dr. Said 30% optic nerve damage &  2 others  say not that much.  Can percentage be relied on?

Need to follow : Patients can lose nerve fiber layer before it produces visual field or visual acuity is affected. You need to be followed over time looking at all parameters: visual acuity, intraocular pressure, nerve appearance, oct and visual field an past medical history. Initial oct are compared to age-matched controls. Your optic nerve could be tilted or outside the normal algorithms. Talk to your doctor. ...Read more

One ophthalmologist said 30% optic nerve damage, one said he doesn't use percentages & another said it was lower. Why the different opinions?

Subjective exams: Examining the optic nerve requires the ophthalmologist to make a 'best guess' at the changes seen on examination. Because everyone has a unique appearance to their optic nerve, the assessment is rather subjective. Although there is imaging available (hrt, oct) none of these measures is precise. ...Read more

Could progression of visual field loss be related to optic nerve damage that occurred 5 mos. prior or is that not long enough for it to be seen.

Could progression of visual field loss be related to optic nerve damage that occurred 5 mos. prior or is that not long enough for it to be seen.

See an eye doc: It isn't clear what is the cause of the optic nerve damage (?demyelination, trauma, autoimmune, metabolic, vascular...?) but if you have progression of visual loss you should be seen by an ophthalmologist as soon as possible. ...Read more

Have 30 percent optic nerve damage due to open angle glaucoma. How many years would it take to incur this amount of damage?

Have 30 percent optic nerve damage due to open angle glaucoma. How many years would it take to incur this amount of damage?

Variable: Glaucoma tends to be a slowly progressing condition. Damage typically occurs over many months or years; however. It also depends on how high your eye pressures are. People with very high eye pressures may develop damage more quickly. It is very important to have regular follow up with you eye md to ensure your eye pressures are controlled adequately. ...Read more

Neuropraxia (Definition)

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


Nerve (Definition)

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
