Hi,
My sister is having a similar problem with dialting pupils and often one is larger than the other, currently she is going through the process of getting all the blood tests and scans to rule out possible causes ( many of which have been ruled out so far). I just noticed that her experience is simililar to yours and another person who posted about this experience with onset after a period of acute anxiety.... my sister was very stressed due to a few factors prior to these visual problems beginning, I just wonder if there is something about anxiety/stress which precipiates this problem....
Hi Kath1204
Sorry I never received your reply! It turned out to be a medication I was handling of my daughters (hyoscine patch) something in that was dilating my pupil!,
Hope your sister got to the bottom of her dilated pupil with no serious illness found.xx
