Optical Illusions Brain Teasers
There's this thing going around the Internet about a dress that looks white/gold to some people and blue/black to others. Why does that happen? Is it an optical illusion or some eye-brain thing?
Beyond my pay grade: This article is pretty good explanation: http://www.wired.com/2015/02/science-one-agrees-color-dress/ ...Read more
No, but: The visual phenomena of migraines is caused by changes in blood flow as the arteries in the head narrow (spasm). Brain tumors can also cause visual changes, usually loss of peripheral vision, but other visual phenomena similar to migraines are known to occur. Brain tumors are rare; migraines are not. ...Read more
My sister had a car accident and suffered from brain bleeding and her left optic nerve was damaged , my question is..can the optic nerve be repared?
If am having optic neuritis and brain lesions but its not MS, what are the other possible conditions?
THE USUAL SUSPECTS: Although this could be "Clinically Isolated Syndrome", with eventual clinically definite MS, other considerations could include an NMO spectrum disorder (get NMO-I, aquaporin-4 antigen), but consider sarcoid, a vasculits like lupus, Lyme disease, HIV, syphilis, Sjogren's, and perhaps B-12 issue. Statistically,, you have >80% chance of MS confirmation within next 14 yrs, if you had only one lesion ...Read moreSee 1 more doctor answer
I have been having some MS like symptoms. Mri shows brain stem lesions n fluid on optic nerve sheaths. Could this be ms?
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 moreSee 1 more doctor answer
I have brain injury that leads to blurry vision, is this something that optical glasses will be apple to fix?
Are all or any types of brain tumours visible in an eye exam? As in, could it be seen or show as pressure on the optic nerves?
Sometimes: Some brain tumors are large enough to increase the pressure inside the skull. That pressure can be transmitted to the optic nerve and show up as papilledema and swelling. There are other more common causes of papilledema and swelling. An eye exam can show a possible brain tumor but often will not. Sometimes tumors are also found if they affect a person's visual field. ...Read moreSee 1 more doctor answer
Can you tell me if someone has brain injury that leads to blurry vision, is this something that optical glasses will be apple to fix?
They found pressure in my brain and I have an optic nerve swollen behind my right eye..how serious can this get if its not treated asap?
Optic Nerve Edema: Increased intracranial pressure can result in papilledema or swollen optic nerve heads secondary to elevated intracranial pressure. Generally this is a bilateral process due to the pressure being distributed to both optic nerves. If it's unilateral this may indicate direct compression of the optic nerve. This should be addressed sooner than later to avoid optic nerve atrophy and visual loss. ...Read more
Had normal brain MRI in 2014 (headaches and optical migraines). Doc mentioned white spots apparently from the headaches. It scared me tho. common?
Mixed bag: This web article is on point: http://www.dizziness-and-balance.com/disorders/central/pvm.htm About half of normal folks over 65 have T2 abnormalities (white spots). Folks in their 40s with migraines can also present this way. It is nonspecific though so a repeat MRI in a patient with continued symptoms could be considered, mostly since there is little risk due to MRI in patients who can have them ...Read more
Why do I need a brain and orbit MRI if i've not had optic neuritis and my last brain and spine MRI was ok? What are they looking for?
Progression: I am assuming you are dealing with ms? If you are, then the MRI is likely to monitor progression of lesions. If you did not have any lesions prior then they may be looking for new lesions that could suggest changes in disease progression or a lack of new lesions defining response to certain treatments. While i cannot say for sure without knowing more, that would be a normal course of action. ...Read moreSee 1 more doctor answer
Can a brain tumor cause problems in other parts of the body? (ex: stomach ulcers, sickness) if a brain tumor is present near the optical part of the brain, can it cause problems in the body such as sickness?
Have infrequent optical migraines.brain MRI normal and see eye doc regularly. They are not concerned. Should I worry?
Don't worry: With a normal MRI and eye exam you should rest assured that they aren't dangerous. But migraines are a leading cause of disability according to the World Health Organization, so if they ever start interfering with your life and you want to discuss ways to make them less frequent and less severe, I'm available for a virtual consult. Good luck! ...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 moreSee 3 more doctor answers

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
