Seeing dark ring circle vision in my eye

[dreamerdelight]

I have a dark ring circle in my vision and it started 10 days ago. I went to my eye doctor and my retina and cornea checked out OK. Do you know what causes the dark ring vision? Is this permanent? Thanks.

Is it still going on

I also have visual snow. This came about 3 years ago. It looks like I am looking through a haze (a bunch of white spots). It looks like a tv screen with no cable input (gray, black and white static). There is no explanation for visual snow yet.

I have the same thing. It looks like a dark circle in the center of my vision. When I blink my eyes, I can see it. I went to a retina specialist and was told it was fluid buildup in my eyes. Kind of like a gel that gets trapped. He could not see anything wrong with my eye. It was just a best guess answer he gave me. I have had this on and off for 8 years. I believe it is correlated with dehydration. If you stop drinking sodas, tea, coffee, alcohol, etc., you should notice a difference. Let me know if you figure out what it is.
