I've had flashes for years. They have been diagnosed as occular migraines, but I don't get a headache with them. When I do get migraines with my period, I don't get auras. The floaters started a couple of years ago. First in one eye and then the other. My vitreous was in the process of detaching, although I'm fairly young for that to happen. Doc kept a close eye on my eyes for a few months. I had my eyes dialated every week for a while and was told to lay off any high impact stuff. What fun that was.
