The Optic Disk Is Where The Optic Nerve Leaves The Eye Ball
The visual pathway: Light passes through the cornea, which is the front "windshield" of the eye and helps focus the light. The iris works as a muscle to increase or decrease the size of the pupil; this controls how much light comes into the eye. Light hits the retina, which converts the light into signals which are sent, via the optic nerve, to your brain. ...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
Nope: It can drift backwards in the conjunctival fornix and be hard to remove, though. ...Read more
2 different things: There are many types of cataract. Posterior subcapsular cataract refers to cloudiness on the back part of the lens just under the capsule. This may be caused by injury, steroids, elevated blood sugar and aging. Ischemia of the optic nerve means that there is or was an episode of poor blood flow to the nerve which may result in vision loss. ...Read moreSee 1 more doctor answer
If vision was completely lost due to a craniopharyngioma, was the optic chiasm damaged or another part of the optic nerve?
Report visual fields: If the chiasm was affected then, you'd have lost visual fields in BOTH eyes. If you had visual field loss only in one eye then, it is more likely that the problem is in front of or beyond the chiasm which could be then, an optic nerve or one set of optic radiations. ...Read more
If the nerves inside the eye like the ciliary nerves get damaged could it effect the color of the iris resulting in a darker colored iris?
What is the name of that illness which is inside the nerves of the brain when the nervous currents can't cross the nerves of the brain in left side?
not sure: Not sure i understand the question. Do you mean like a disconnection syndrome? Maybe try rephrasing your question. ...Read more

Weakness or paralysi: The ventral root contains the motor fibers which control our muscles. Because muscles have multiple nerve roots innervating them the result may only be weakness in a particular group of muscles or could be paralysis if the particular nerve root is the dominant root. ...Read moreSee 1 more doctor answer
Please explain lumbar MRI -there is a narrowing of the lateral recesses, particularly on the right but without displacement of traversing nerve roots.
Lumbar MRI findings: The explanation means early degeneration is causing compression of the spinal fluid sack, but is not putting pressure on the nerves. The results would not explain leg pain, but may cause back pain. Please review with the ordering physician to correlate your symptoms. ...Read more
If you have a pinched nerve in the upper
spine and it causes permanent paralysis, is the paralysis only in the location the nerve attaches to?
Yes: That is correct. The muscles connected to the damaged nerves will not work correctly, or will not work at all. Other nerves that are undamaged will continue to send signals to their muscles, and keep them moving properly. However, muscles work together as groups of muscles. That means weakness or paralysis in a few muscles can make a limb malfunction even if other muscles in the limb are working. ...Read more
Depends: If the area of the brain damaged is the occipital lobe or the optic radiations, then visual field defects can occur. Generally damage at its maximum occurs immediately and over time there can be a lessening if the areas recover. Of course, the larger the initial damage, the more changes will be detected. Your neurologist can help sort this out. ...Read more
