my daughter will have times of anisocoria (sp) which means different sized pupils. it is no big thing. She saw an optha and all about it. This was noted about 3yrs ago. It went away and I haven't noted it since. AND I've had pupils of different sizes. I think I watched that phenomena for several months a year or two ago.
You know that our pupils are controlled by two muscles. We also know that peeps with anxiety often have muscles that don't react just right. they are somewhat amped up or tense. In my opinion, the pupil muscles, being that they are muscles too, can be just as affected by anxiety and stress as any other muscle.
I have read, here maybe, and an article or two, that anxiety and stress can affect pupil size too--but haven't been able to find those particular sources just now. I also did my own perusal of the google man------yes most of what you find with pupil stuff is "scary" stuff. You won't find much that says anxiety will cause it and what not. BUT it should be noted that there quite a few--many actually--anxiety forums (I just spent about 10 or 15 min doing a quick read) that have people posting about unequal pupil sizes. So it seems like a fairly common phenomena. Our eyes are fairly easily affected by stress and anxiety. I am currently under an opthamologists care for fluid (blood vessels) leaking behind my retina in my right eye. It is called central serous chorioretinopathy and it is caused by excess cortisol being produced in my body which caused the blood vessels to leak behind my retina. All brought on by the extreme emotional stress in my life in the last month that included the death of my mother. In most cases, once the stress is relieved, the condition resolves itself. It can take around 2 months to do so. If not, according to info I've read online, I may require laser surgery. BUT in the interim I have to deal with some pretty substantial vision issues. SO if I can leak fluid behind one eye, it isn't sooooo hard to conclude that our pupils can be a bit off due to cortisol production, imo.
So I am going to go back to my earlier statement-----and inspite of the dearth of information confirming that "yes anxiety/stress can cause unequal pupils"--- and say that I think the muscles in the pupils can be just as affected by stress/anxiety as any other muscle in the body. Further I will say if we pay a lot of attention to it, it will only get worse or appear to do so.
now having said all of that, if you want to see an opthamologist, it is your prerogative. I mean when my daughter had it, I took her to an optha. AND when I my eye issue started up, I went to the opthamologist myself. remember anxiety/stress is TOUGH on a body. This is why it is imperative that we get anxiety under control. While we can't always control the stress in our lives, we have to learn how to be kind to ourselves.
