I have the odd dotes as well and in the last five years have developed migraines. I had noticeable vision change during my last migraine that did not go back to normal so I went and got an MRI. The doctors found an arachnoid cyst in the posterior fosse of my brain (check the spelling I’m not exactly sure).
I had the little specs of light all over my vision on a flat (2D) plain in front of my eyes. To some one that does not have them it can best be described as looking at the snowstorm on a TV screen. I also have a high-pitched ringing in my ears almost like those lights at clothing stores.
If you have dots in your eye sight ringing in your ears and migraines I would recommend talking to your doctor about getting an MRI.
