I will sense something in my vision in my right eye. It begins as a blurry spot and becomes a prism that expands until it goes away. I had this today and when it went away, I was extremely dizzy for about 3 or 4 minutes. My blood pressure was 132/80 and my blood sugar was 112. I had no headache or sick stomach. Has anyone hearrd of this? I am going to the doctor on Tuesday, but I am curious. I have not experienced this for over a year. It occured once yesterday and twice today.View Thread
