Temporary loss of peripheral vision?!

I have had a few differentt instances where I loose my peripherall vision for about 20 min or so!. The last time it happened I was sitting on the couch watching T!.V!. and nothing else was going on!. I had no pain with this, my eyes seemed to have black floaterss everywhere I looked and I could not see out of the sides at all!. All I could see out of the sides was salt and pepper!. I go to the eye doctor for it Thurs!. but have been looking up online and can't decide if it is one of these migraines that impair your vision!. I did not have any other problems and I was not stressed!. I do have a history of high eye pressure, but the doc!. says its not to high and not to worry just yet!. Has anyone else had a similar instance or any idea what it might be!? Just though I would ask for piece of mind like I said I go to the doc!. thurs!. for it!.Www@Answer-Health@Com
