Thoughts while pedaling.... like a grease stain

A while ago I took a nasty fall on bike. It was so bad that I dented my bike helmet and received a huge contusion (which I still have).
This week I woke up with what can only be described as a grease blob
floating over my right eye...any where I look the grease blob floats right over to the center of my vision. The eye doc said that an anchor that holds a thin membrane to the retina has become detached and now is floating through the eye being held by a tiny thread. If that thread detaches it could take some of the retina with it. So off to the macular doc I march for some laser work.
