Hello . Before I start just let me start by giving a brief history . I've had a dilated eye exam in December which was clear . After that I've had a couple of normal undilated eye exams which were also normal . My number is also stable . No vision problems either But one thing which really confuses me is that I occasionally get a very small black spot in my vision it's yransoent it comes and in a second vanishes . This is a floater or a natural visual phenomenon ? Thanks :)
