Treating Optic Nerve Damage With Vitamins
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
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
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
Can you tell from the eyes the window to the body about severe nerve damage anywhere in the body not just the optic nerve?
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
Optic nerve: The vascular issue is a reflection of a systemic vascular process and will need to be addressed by your internist and eye doctor in consultation. ...Read more
On average what percentage of optic nerve damage must there be in order to show a loss of peripheral vision on a field test?
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.
Sorry to hear of your optic nerve compression, and I assume most of the difficulty occurred at the optic chiasm. First, make certain no further compression is present. Secondly, confer with your neurologist about visual approaches specific to your problem, and have ophthalmologist evaluate. A medical food MetanX, has biologically active B vitamins, maybe worth a try???
No real proof however! ...Read more
Could bending over and putting your head upside down to wash your hair cause optic nerve damage in glaucoma.
Probably not: Please follow up with your PCP if any other concerns. ...Read more
I am type2 DM having normal tension glaucoma with 40% optic nerve damage. Is it due to my diabetics or hereditary?
Tension glaucoma: Probably both but worthwhile checking with your eye doctor. ...Read more
30 percent optic nerve damage. Pressure 31. If slt gets it down to 25 is it possible to be enough to stabilize? Doc says I could try.
Possibly: It is possible for an slt to effectively lower your eye pressure. There are other options to lower pressure including eye drops and even surgery. Depending on your diagnosis, certain options work better than others--this is best determined by someone who has examined you. Ask your eyemd for opinions on these other options if you are concerned about slt or consider getting a second opinion. ...Read more
30% optic nerve damage with no vision loss. Late beginning stage to early moderate stage. Was glaucoma caught early enough to prevent vision loss?
Open angle glaucoma 30 percent optic nerve damage. 58 years old. How many years before damage would be seen. Dr did not screen yearly w/annual exam.
Best to take multipl: Field exams, and look at the severity of the defect and the rate of progression with treatment (plotted against the estimated number of years to live) and you can get an idea of how long before very advanced damage can lead to actual real life vision changes vs. Merely changes on a test that are not seen in real life. ...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 more
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
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?
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
Not possible: You have not asked a question but damage to an eye will likely disqualify you from military service. Are you actually thinking you could join the military at age 48? ...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
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
