Can you have a tumor in the cranial nerve meninges?
Yes. you can have a Meningioma of the Optic Nerve.
What causes Compressive optic neuropathy?
This is the result of a tumor or other lesion putting pressure on the optic nerve
What if you have a tumor in the center of the brain what can be done?
The brain tumor I had was in the center of my brain. It was located just under the optic chiasm. It was a schwannoma brain tumor which only grows on nerves. It was growing off of my optic nerve. The craniotomy removed it, unfortunately there was nerve damage. I cannot open my left eye, which in a way is good, because my eye points all the way to the outer corner. Thank God the tumor was not cancerous.
Did sandy duncan have a glass eye?
No, she had a tumor behind her left eye which destroyed the optic nerve. She's blind in her left eye, but it's real.
Would an eye doctor see anything during an exam that would point to a brain tumor?
Only if the tumor was located around/behind the eye, and thus pressing against the optic nerve. A brain tumor can only really be picked up via a C.A.T. scan.
Does the optic nerve cause a blind spot?
The optic nerve (also known as cranial nerve II) is a continuation of the axons of the ganglion cells in the retina. There are approximately 1.1 million nerve cells in each optic nerve. The optic nerve, which acts like a cable connecting the eye with the brain, actually is more like brain tissue than it is nerve tissue. As the optic nerve leaves the back of the eye, it travels to the optic chiasm, located just below and in front of the pituitary gland (which is why a tumor on the pituitary gland, pressing on the optic chiasm, can cause vision problems). In the optic chiasm, the optic nerve fibers emanating from the nasal half of each retina cross over to the other side; but the nerve fibers originating in the temporal retina do not cross over. From there, the nerve fibers become the optic tract, passing through the thalamus and turning into the optic radiation until they reach the visual cortex in the occipital lobe at the back of the brain. This is where the visual center of the brain is located. The visual cortex ultimately interprets the electrical signals produced by light stimulation of the retina, via the optic nerve, as visual images. A representation of parasympathetic pathways in the pupillary light reflex can be seen here: parasympathetic response. The beginning of the optic nerve in the retina is called the optic nerve head or optic disc. Since there are no photoreceptors (cones and rods) in the optic nerve head, this area of the retina cannot respond to light stimulation. As a result, it is known as the "blind spot," and everybody has one in each eye. The reason we normally do not notice our blind spots is because, when both eyes are open, the blind spot of one eye corresponds to retina that is seeing properly in the other eye. Here is a way for you to see just how absolutely blind your blind spot is. Below, you will observe a dot and a plus. This The End The optic nerve causes a blind spot because it is a continuation of the axons of the ganglion cells in the retina.
