Myelinated Nerve Fibers In The Eye
Nerve fibers: Thin nerve fibers can sometimes be seen in glaucoma and other nerve diseases of the eye. You should take the results of an oct with a grain of salt. Although it is a very good test, the results are not always indicative of a disease, and should only be used when also taking into account your medical and eye history, as well as the results of your eye exam. ...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
Pressure atrophy: One theory is that pressure too high for the back of the eye to withstand causes constriction of the blood flow with atrophy of the tissue (nerve fiber) supplied by that blood stream. They then atrophy and this is the basis for the thinning. Lowering the pressure below that threshold for damage prevents further blood vessel constriction and allows the remaining nerve fibers to stay healthy. ...Read more
More Specific: If you are referring to pulsation of the lid it is usually due to stress, fatigue and caffeine intake (obicularis myokimia).

What is meant by hole in the eye nerve. What are treatments available. How safe is that for 2 year old kid?
Rare disease: I presume you are referring to a optic nerve Coloboma, which is a rare congenital abnormality of the optic disc of varied severity that causes moderate to severe visual field defects. Unfortunately, the defect is not reparable, and the visual field loss is irreversible. Hopefully you have had your 2 year old examined by an Ophthalmologist to elucidate the diagnosis & help discuss management. ...Read more
How long does it take for a nerve to regenerate in the eye after experiencing double vision? Diabetes, and other health problems could be culprits.
6-12 weeks: If double vision is from a diabetic mono-neuropathy, meaning damage to one of the nerves innervating the eye muscles, then typically it takes anywhere from 2 to 3 months to regenerate. These are vascular insults and can come from diabetes or high blood pressure or other vascular diseases. ...Read more

Can herpes enter the body through the eye? For ex spitball to eye/eyelash area? Or contacted from another part and then rides up the optical nerve?
Almost never: Most have been exposed to herpes during childhood and carry resistance. This includes the eye and its connecting structures. Herpes will only enter an adult if there is pronounced immunosupression or extreme debility. And a normal adult cannot transfer herpes from an infected sore on the body to another spot on the body. ...Read more
Everytime I bend over I get a pain behind my left eye as soon as I stand up it goes away. I also have a swollen optic nerve in the eye. What is wrong?
Intracranial HTN: Seems like you may have high intracranial pressure. Lying down, bending down raises the pressure, standing lowers it. Papilledema is classic for high icp. You need to be seen by an ophthalmologist to determine cause... Oral contraceptives, hormones, obesity, vitamins, steroids, tumors can all lead to high icp. ...Read more

So each step leads to the next step in your management. Not sure what you meant by 'buy empty space? ' Please clarify. Thanks! ...Read more

Blurry vision: Blurred vision and changes in color of vision can be due to: optic nerve perfusion issues (check all meds; BCP often culprit; check Blood pressure), needing new glasses, brain flow issues (ie, ocular migraine: VA changes without headache); be sure pupils & HVF visual field were done to be sure all is ok. ...Read more

When you have Eye problem, it is not specifically on the eye itself, but in the visual cortex of the brain, some nerve damage. Is it true?
Visual problems: When a person has a problem with vision, they can have a problem anywhere from their cornea. Lens, retina and along the optic nerves to the visual cortex of the brain. Our retina is actually part of our central nervous system, as are the optic nerves. The muscles that move your eyeball are controlled by cranial nerves as well. Ophthalmology is the specialty of medicine that treats eye disorders. ...Read more
I have a blind spot (not the usual blind spot) due to high BP of the eye & low damage of the optic nerve, could it be treated by (medicine/surgery)?
I went to the eye doctor for the first time - the optic nerve size is slightly different between my eyes. Why would this happen/should I be concerned?
No: Your ophthalmologist would have told you otherwise if there is a need to do something different, I believe he meant the optic disc rather, not the optic nerve. Just follow up routinely, with the ophthalmologist for fundus (back of the eyes) exam, and ocular pressure measurements, best wishes ...Read more
, if the entire retrodiscal tmj tissue breaks could it lead also to nerve damage? (as numbness on the eye lid, mouth corner etc).
It is possible: Because the retrodiscal tissue is vascular and highly innervated. See Orofacial Pain specialist for evaluation and redirection of the condylar loading forces from the retrodiscal tissue to the intermediate zone. ...Read more

Some objects similar to fiber or string are afloat in my eyes from many years ago. What are these objects? What is treatment? Isn't it dangerous?
Vitreous Floaters: The back part of the eye is filled with clear jelly-like substance called vitreous. As it begins to liquefy over time, some of the fibers and debris become visible, particularly against a white background. New floaters and a change in your normal pattern of floaters can be a sign a of retinal damage or a pvd. You should get checked by an ophthalmologist. ...Read more
