Causes Of Unequal Pupils
What would cause unequal pupils in a patient that has been in a medically induced coma for over a week?
Depends: It is important to know if this had been true prior to the illness onset. If not present prior the possibility is high the pt has had some intracranial catastrophe such as brain bleed. The unequal pupils suggest a bleed or other intracranial event. Need to speak to the neurologist. If not under the care of neuro get a consult. ...Read more
What can cause unequal pupil size? It is not very much bigger than the other one and it contracts fast to light. And should I worry?

Pressure in the left side of my head for nearly 2 weeks. Doesn't cause any pain but it does cause dizziness and unequal pupil size. What is it?
Can ear infection/disorder/disease or vestibular issues cause unequal pupil size? Opthamalogist says eyes fine and he doesn't suspect neurological.
Vestibular lesion would not alter your pupil size. If an ophthalmologist examined you and determined it to be not a cause for concern, please let it be.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats.

Painless pressure in head won't go away with painkillers? Pressure in head can cause dizziness, drowsiness and anisocoria (unequal pupil size)?
Without an actual examination, I cannot give specific medical advice on your particular health,
but, signs of a life-threatening amount of pressure in the head (tumor/bleeding/mass as possible causes) would include
drowsiness, change in pupils, change in mood/alertness. And sometimes other neurological symptoms incluing balance/dizziness or weakness or seizures. ...Read more
Anisocoria: Is a condition of unequal pupil sizes. Affecting 20% of the population, it can be an entirely harmless condition or a symptom of more serious medical problems. Have it checked out. If it is harmless, just ignore it. If there is an underlying medical problem, then that is what needs to be treated. There are medicines to make a pupil larger or smaller, and the strength can be adjusted. Don't do that ...Read more

YouDon'tSeeEyeToEye: It depends on what's causing them but even then there's not much to offer except maybe eye drops that counteract whatever is causing the inequality (dilated on one side, constricted on the other or vice versa) unless the problem is in the eye and irreversible. Sometimes a systemic medication based on the cause. Rarely surgery. If that's what you have, start with a neurologist or opthalmologist. ...Read more
Unequal pupils r > l. R eye feels swollen. R sided headaches. Occasional bright dots/sparks in r vision. Ct normal. Us carotids nil. What is wrong?

Horneres syndrome (but affected pupil should be smaller) / from trauama? / addies tonic pupil / optic neuritis (multiple sclerosis) / tumor (did the ct include brain and orbits?). ...Read more
Are two normal 3 tesla mra/mris and a normal cta enough to exclude brain aneurysm in the case of unexplained unilateral head pain and unequal pupils?

Unequal pupils r>l, both reactive, intermittent r eye pain and r sided headaches up to 3months. Noncontrast CT normal. Dizziness past few days. Tumor?
Neurologist, MRI: First, don't panic. Uneven pupils, aka anisocoria, are often due to a benign condition like migraines which would also explain the eye pain and headaches. However, more serious causes like multiple sclerosis and brain tumors are possible. You should see a neurologist who will likely order an MRI of the brain as part of a complete evaluation. ...Read more

Probably not: Unless you have had some direct injury to the eye or to the nerves to the eye, it is probably ok. There is commonly a little difference between pupils and if the difference is 1 mm or less, that is considered normal. If you vision is fine and the eye feels fine, don't worry about it. ...Read more
Pupils dilate and: Constrict under control of cranial nerve 2 and 3. 2nd senses light and 3d adjusts pupil to control light input. No dilation = deficit in one or the other or a medication in the eye has poisoned muscle function. Would be very unlikely to inadvertently notice that both pupils do not dilate. Close eyes in bright room then open while friend observes. If they constrict they must have been dilated. ...Read more
What conditions would cause sudden onset and persistent bilateral medial corectopia in a person with previously centered pupils?
Several things..: If it is in fact corectopia, and not esotropia or pseudoesotropia, then the causes include progressive iris atrophy and other rare developmental anomalies, as well as post-traumatic scarring. None of these are likely to cause sudden onset of corectopia, though. Since these conditions can sometimes cause glaucoma, it would be best if an eye md (ophthalmologist) examined you. ...Read more
Adrenaline surge...: Adrenaline is the principal mediator of the "fight or flight" response. This prepares your body for immediate action. Pupils dilate to increase light transmission, heart rate and blood pressure go up and blood is shunted away from other organs to the skeletal muscles. If this occurring in the absence of a stimulus, it is likely due to hypoglycemia or low blood sugar. Check for Insulin resistance. ...Read more
