Is it true that a tumor on the optic nerve is dangerous?

Is it true that a tumor on the optic nerve is dangerous?

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

Nerve (Definition)

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

I was told that that I have a tumor on the optic nerve. Should i be worried?

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

Hi, what's the difference between benign cyst and benign tumor on optic nerve? Thank you.

Hi, what's the difference between benign cyst and benign tumor on optic nerve? Thank you.

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

Hi, what's the difference between a benign cyst and a benign tumor on optic nerve? Thanks

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

Is it normal for optic nerve tumors to cause impairment in vision (neurofibromatosis 1)?

Is it normal for optic nerve tumors to cause impairment in vision (neurofibromatosis 1)?

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

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

I have optic nerve damage from a pituitary tumor is there anything I can do for my vision?

I have optic nerve damage from a pituitary tumor is there anything I can do for my vision?

My response: 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

Maybe not: Some brain tumors do not put any pressure on the optic nerve. On the other hand, there are lots of other causes of vision problems. It is probably not worthwhile jumping to conclusion that your vision problem is caused by a brain tumor. ...Read more

Can you list eye manifestation due to brain tumor compress optic nerve?

Can you list eye manifestation due to brain tumor compress optic nerve?

Visual field defects: As the tumor compresses the optic nerve, there will be a visual field defects. This can be in one eye if it happens before the optic chiasm or in both eyes if it happens after the chiasm. If there is any visual field defects, the tumor should be removed. ...Read more

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

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

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!

Highly unlikely: In rare cases, very severe sinusitis could affect the blood supply or blood drainage of the optic nerves. However, a person with this problem would likely have other symptoms as well, such as severe headache, other cranial nerve palsies or frank meningitis. ...Read more

Explain the optic nerve?

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

Neoplasms (Definition)

"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
