Hi. I have had this black/gray spot in my vision for over a year now. It always seems like it is in the same spot which is just to the lower right of my central vision. It moves when I move my eye and I notice it more when I look at a computer screen or am outside. It reminds me of a floater except it is always there and in the same spot (and is darker than my usual floaters). I do get migraines with aura which I have had for many years. I have had a MRI with and without contrast and a CT scan which came out fine. I also have had numerous eye exams (the main ones for glaucoma) which they said came out fine. I just want to have an idea of what this could be becuase it is really bothersome and it does scare me sometimes. Could it be damage from a migraine and is it something to worry about? Could this be a floater that just won't go away and if it is how come the eye doctor could not see it? Just a little more info: 23 years old, female, and I do have alot of anxiety and stress.
