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.
Rarely reversible. Optic nerve damage can happen for a variety of reasons, including vascular causes such as "strokes, " inflammation, compression, and infiltratration. A few of these causes can rarely be reversible with time or interventions, but the exact cause needs to be determined.
Almost never. Sometimes you can get lucky, and some of the optic nerve dysfunction is due to swelling, and when the swelling resolves, the vision improves. Thats the theory with ischemic optic neuropathy. But even so, the improvement is marginal.
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.
Nerve damage. Sorry but all too often nerve damage is permanent...Ask your ophthalmologist what caused it and what is your future prognosis. Keep us posted... Dr. Sibley.
See details. Multiple sclerosis is a common cause. Other causes include trauma, infection, emboli (blood clots), vascultis or infarctions.
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.
I'm really scared I have optic nerve damage. .. Due to me being under too much light. Or something the colors seem dull and I can't see much detail?
See Ophtho. Being scared will not help you. If you have optic nerve damage, than move forward and assure you see the Ophthalmologist to be sure you are doing all you can to keep well in the future. Best wishes to you.
Please repost. There are many causes of optic nerve damage in the eye, from vascular causes to glaucoma to tumors. Please repost your question so we can address it.
Optic nerves. A thorough exam can help determine the extent of the damage in many cases along with visual field and oct testing. A neuroophthalmic exam may be required in addition to an MRI or ct scan in some cases.
Control pressure. Increase of intra-ocular pressure must be addressed and controlled, as damage to the eye and loss of vision is a consequence of glaucoma. (may start to be an early loss of vision in the lower medial field (bjerrum scotoma) see a trusted ophthalmologist, get the pressures controlled with eyedrops, and protect your eyes.!
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.
Several. Optic nerve damage can range from trauma to chronic diseases such as diabetes and autoimmune processes.
Many. Trauma (head and/or eye), alcohol and other drugs, high blood pressure, diabetes, multiple sclerosis, optic nerve tumors, brain tumors, some heart and antibiotic medications, genetic disorders.
Optic nerve. Optic neuritis, ischemic optic neuropathy, compressive optic neuropathy, toxic optic neuropathy, traumatic optic neuropathy, hereditary forms of optic neuropathy.
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.
