Anisocoria In Children
Unequal pupils: This is the technical term for pupillary openings that do not match within the usual 1-2 mm difference that is often normal. Anisocoria would be diagnosed if the difference is greater and it has to be more that at 5 mm difference for a casual observer to see the difference in ordinary lighting. ...Read more
Unequal pupil sizes: If there is a difference between the sizes of your pupils, you have anisocoria. If no medical condition or disease can be found to account for it, it is termed "physiologic". Check old photos with a magnifier to see if it is old or new! It might result from minor gestational or birth injury! Generally nothing to worry about if not associated with something bad and if not progressive. ...Read more
Contact lens: One easy way to hide a difference in the size of the pupils would be to wear a pair of colored contact lenses. Depending on the nature of the difference [trauma] for example, a custom made contact can be ordered to match the normal eye. ...Read more

Can aneurisme cause seesaw anisocoria that comes and goes? Or Would aneurisme cause constant singlesided anisocoria?
If anisocoria is physiologic, is it normal for it to occur spontaneously in adulthood? Is it common for the discrepancy to increase in dim light?
Anisocoria: Yes possible but must be rare if greater than 1 mm which would be hard to detect in most folks. What does your Dr. Think is going on? There is a good discussion at Wikipedia. ...Read more
Normal or not: In some people there can be a slite natural difference between pupils. If there is no neurological basis for this then it could be from a horner's syndrome from neck trauma, old direct trauma to the eye, old intraocular inflammation or several other potentially benign origins. There is really no treatment for qualizing the difference in pupils. ...Read more
None: Benign anisocoria is usually very subtle and tough for observers to spot. Anisocoria, or different sized pupils, can be from a number of neurological and ocular problems. But benign anisocoria is a minimal (about 1mm) difference between the pupils in an otherwise normal individual. If you have a larger difference than this I would see an ophthalmologist. ...Read more
Depends: There is a sympathetic nerve trunk which travels from the spine up the carotid in the neck supply the eye including the size of the pupil. If this nerve is disturbed there can be pupillary changes. You would likely see also a droop of the lid and a change in the pattern of sweating on that side of the face. It is called Horner's syndrome. ...Read more
Anisocoria: Start with an opthalmologist, who can refer u to a neurologist if needed. ...Read more

Can lexapro/celexa cause anisocoria? Since I started on this type of med my right pupil has been bigger than my left but still responds to light
MRI/A for head pain/anisocoria read by neuroradiologist said patent PCOAs could not be defined on either side. Could there be an aneurysm in this area then that wasn't seen? Or could I not have PCOAs?
I've had pretty noticeable anisocoria. My MRI was clean and neurologist says my pupils are round and responsive. Could this be caused by taking SSRIs?
See neuro-ophthalmol: If this is anisocoria of new onset, then further testing than MRI shoud be done. Neuro-ophthalmolgists delight in such cases. Do you have drooping lid (ptosis), is your face dry on that side? Is there a history of trauma to the neck? Was the MRI of your brain or did it include your upper chest and neck? I don't think SSRIs would cause this. ...Read more
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
