Teenage daughter has one eye pupil bigger than other!

[mini182]

My daughter is 13 and has one pupil bigger than the other but it’s intermitting! She can go weeks without it happening and then it can happen ever day for awhile!

It’s been happening for several years, at least 5/6 maybe longer, we have been to several opticians about it and they said they can’t see anything wrong, as long as she has no headaches, blurred vision and as long as the pupil reacts to light.

Has anyone else had this? Can this just be a normal thing? I’m so worried something serious is not being picked up 🥺

Yes ds had this. We went to the optician. He said we must make sure he wears proper sunglasses as it can lead to headaches if too much light gets in. He still gets it every now and then (and he’s 24 now!).

I have that - got It checked out and it’s physiological apparently, ie not a disease. Worth asking for a referral to ophthalmology but I wouldn’t panic.

Both my daughters have this. My youngest is more noticeable she is 6 we got them checked at hospital she had to stay over night but my 9 year old didn't. It's just the way the eyes react to light.

My husband has this. Was referred to ophthalmology, had brain scans and all sorts. Eventually told that it's just the way he is. Never caused him any problems.

I have it. Normally it happens when I'm tired. Never caused me any problems. I did have it checked out as a kid though and it's probably worth doing.

I must say my vision driving at night (so the light/dark contrast and adjustment) is crap though, not sure if connected.

Oh thats interesting! I have the same - its been noted a few times by opticians etc. The difference is usually very slight in normal daylight / household lighting but I do get very watery eyes if its bright (sunglasses help) and I hate night driving - but I also have astigmatism so had put it down to that.

I have astigmatism too and it was only thinking about it on this thread that made me wonder if the pupil size thing might be a factor!

Yes, I have this. The difference is even bigger in certain lighting and when I’m tired etc.
