Tumor Pressing On Optic Nerve
Possibly: Tumors anywhere can be dangerous. Optic nerve tumors are most commonly gliomas which are not malignant but which interweave with the nerve, disturbing vision and removal is frequently accompanied by permanent loss of vision. This is not "dangerous" but loss of vision is not a good thing. Other optic nerve tumors are more rare but do need to be inbestigated. ...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
Sometimes: Most optic nerve tumors are benign although they can grow and cause the nerve to fail. The two most common of these types are gliomas and meningiomas. Tumors can also be metastatic from other sites in the body. A few rare types like schwannoma also can do this any such tumor should be diagnosed and treated if possible. ...Read more
How can tumor on the optic nerve be treated? Is surgery the only option? Any medication needs to be taken?
Seek Oncologist: It is difficult to give you a simple answer. Cancer can be treated with surgery(where possible,without losing function) or Radiotherapy.Only an eye specialist(Ophthalmologist) can guide you further. A team of an oncologist and Ophthalmologist together can help this patient. ...Read more
Cyst & tumor differ: A cyst is defined as an open space (sac) with an epithelial lining. This space may be filled with fluid, cellular debris, empty, etc. In general, a tumor is a solid growth, but may have cystic components. They can be composed of many different cell types. In this case, both are benign, but being on the optic nerve, they could still cause problems due to compression. ...Read more
Good question, but: Not always a simple answer. Some tumors form cysts. Generally a cyst is trapped fluid in a surrounding layer of non-tumor tissue. "Benign" is a complex term in the nervous system. A tumor cell type can be benign by its growth pattern (doesn't invade or "metastasize") but still a concerning problem because of where it is (on an eye nerve, for example). See ophthalmologist (not optometrist). ...Read more
Hi, my mom had a tumor on the optic nerve 0.25x0.36x0.4cm. Is surgery the only way to remove it? How can it be treated?
Tough to determine: Not knowing the pathological characteristics of the tumor, tough to advise you. Some cases, gamma knife is useful, others might respond to irradiation or chemotherapy, but in some cases, surgery is life saving. But a lesion on the optic nerve might be precarious, and risk blindness. Would get additional opinions from ophthalmology and neurosurgery. ...Read more
Usually: The symptoms are caused by tumor growing and pressing on the optic nerve and nearby structures. Symptoms may include: •involuntary eyeball movement, eyes bulging outward, squinting, loss of vision in one or both eyes leading to eventual blindness this may be losso of peripheral vision or more general loss. ...Read more
Can MRI detect tumors(benign/malignant)? The MRI only shws a lesion at the right optic nerve near the globe.Do i need a PET scan to find out more? Thx
MRI: MRI (magnetic resonance imaging) can detect various tumors, especially if it is used in the context of what is called Multi-Parametric MRI (MPM). MPM uses various characteristics to help distinguish malignant from benign. Google this term to learn more. Thus, one of the variables that should be used is called DWI (diffusion weighted imaging) and that helps decide if a lesion is malignant or not. ...Read more
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
Involuntary eye closure due to light, exercise, and waking. Have had swelling on optic nerve right side. Psuedo tumor with no dx. Any suggestions ?
Is radiation for a squameous cell cancer tumor behind eye on optic nerve
next to brain safe or could it cause necrosis of brain. Do I need proton?
Palliative: Retrobulbar optic nerve involvement with metastatic tumor rare. Squamous malignancies are very few in that area. Chemo and RT given have mostly been palliative. Gamma knife therapy might be better than trying proton beam. With RT and chemo results in general have not been that encouraging. ...Read more
My 7 year old son has to get an MRI after an eye exam that showed his optic nerve is larger than normal. Could this mean he could have a brain tumor?
More complicated : This is more complicated than yes or no. Let's not jump to the worst thing first. Many reasons can lead to optic nerves that are different. Let's see what is causing this finding. ...Read more

Menopause: Hi. Both that FSH & LH are consistent with menopause. It would be vanishingly rare for them to be from a pituitary tumor. Have you lost part of your visual fields? You may have a pituitary tumor, but seems unlikely with high gonadotropins. Pituitary MRI would resolve that. Where in your neck are you swollen? See what your ophthalmologist recommends and talk with your primary doctor. Referral? ...Read more

Unclear cause: The symptoms you describe may be from a number of causes. It sounds like you are under the care of a health professional if you have received an MRI. If you don't feel all of your questions are being answered by the practitioner that ordered the MRI, you can always see someone for a second opinion. Based upon the information provided, a neurologist and/or endocrinologist may be able to help. ...Read more

Can sinusitis be a cause of swollen optic nerves in both eyes? Scheduled for an MRI but very nervous hoping its not a brain tumor. Thanks!
Visual cable: The optic nerve, the head of which is described in the back of the eye by your ophthalmologist as the disc, is the cable carrying visual information into the brain where it ends up in the occipital lobe and interpreted as vision. It contains over 1.2 million fibers as well as supporting elements.A truly amazing nerve. ...Read more
Nerve swelling: Elevated optic nerve means one which which protrudes from the optic disc in back of the eye. This may developmental, or related to eye shape, or to swelling of optic nerve. Ask your ophthalmologist to explain these possibilities to you--it's part of his/her responsibility--i.e., education, instead of baffling you with medicalese. ...Read more
Many causes: The optic nerve can be affected by trauma, infection, vascular occlusion, tumors in the optic canal or on the pituitary, or inflammatory processes like multiple sclerosis. If there is a sudden change in the vision, which is a hallmark of optic nerve dysfunction, see your ophthalmologist right away. ...Read more
"tumor" literally translates as "mass", so even a fresh bruise could be called a "tumor". Doctors use the term "neoplasm" (tranlates literally as new growth) to describe tumors that are abnormal growths of cells. These may be benign or malignant; "malignant" = cancer. In everyday usage, we use "tumor" ...Read more
