The past month I had complete knee replacement. In the hospital and in rehab,as well as present, when I close my eyes I see a black blob with a bright light on the end like a flaslight. I keep thinking everyday that it will disappear, but is still there.

I am concerned about this problem. I called my eye doctor and the nurse told me that if I only see it when my eyes are closed, it has nothing to do with my eyes and could possibly be a brain problem from the surgery. I don't know what to do and would appreciate any information you could give me. Thanks for your attention.
