Around the time I first got my floaters, about five months ago, I started to notice a circular "halo" in my central vision when ever I woke up in the middle of the night. I didn't see it every night. One morning I woke up and saw a fuzzy circular patch in my central vision where everything was distorted. It went away after a few seconds and my vision returned to normal. That day I went to the eye doctor and had a dilated exam. My doctor couldn't see anything abnormal about my eyes. The past few months I haven't had either of these two symptoms until today. When I woke up in the early morning I saw a dark spot in my central vision, almost like a blind spot. It went away after a few seconds and my vision as I type this is normal. I haven't been able to find much on the internet about this, so I was wondering if anyone here has had this happen?
