About 15 years ago my sister had a few episodes of her pupil becoming really big in one eye so you couldn't see the iris and her vision would go blurred in this eye whilst this happened.
Well, last week she had it come back and one day it happened about 12 times. You can see the pupil taking over the coloured bit and she says she can feel it and it goes blurry. She has phoned a couple of opticians but they say they haven't heard of this.
I was just wondering, before she gets an appointment with a doctor (which will be a couple of weeks due to work commitments), if anyone had any ideas or it had happened to them.
Thanks for any advice.
