My left pupil is larger than my right and is not responding at all to light. The GP checked today and it is responding slightly when she moves her finger towards my face. She referred me to an ophthalmologist and said it shouldn’t be anything scary. I was wondering if anyone else has experienced this or if anyone knows what could be causing it? I only noticed it a couple of days ago my my vision has been cloudy on and off for a couple of months. I put it down to getting older as I am in my late forties.
