Flashes of light swimming in front of eyes, not retinal detachment or migraine

What could be causing flashes of light in front of my eyes when I look out of the extreme corners of my eyes? Retinal detachment or migraine precursor has been ruled out.

Ever since I was little I have noticed that when I look at something out of the extreme corners of my eyes I get arcs or flashes of moving light after my eyes come back to center. Sometimes the flashes last up to 10 seconds, swimming across my field of vision until fading away. The last time it happened was when I was in the exam chair and my eyes were dilated and my opthalmologist had been asking me to look off to the right while he examined my retinas. When I asked him why looking out of the extreme corners of my eyes caused swimming lights, he checked right away for retinal detachment but didn't find anything wrong. He pretty much shrugged his shoulders and couldn't venture an opinion as to why that's always happened to me.
Like I said, this has been since early childhood, and while I am nearing 50 and have a few floaters, it has never shown up as retinal detachment. It is never followed by a headache, and always goes away after a few seconds.
