Optic nerve avulsion

I was reading about the eye anatomy (pretty much feeding my fear) and I read that if some rotated the globe (eye) then it would tear the optic nerve. They made it seem that all you had to do was rotate it once and you're screwed. But to explain my fear about all this is lossing my eyes. I have intrusive thoughts about myself taking them out. Is this even possible?

 
I know there are people who can "eject" their eyeballs so that the majority of the eye is out past the socket (looks really gross), and they don't seem to hurt their optic nerve.

I'm not sure what you mean by rotate. I don't think you CAN rotate your eyes. You can "tilt" them around in their sockets but that isn't rotating them which you can't do because of the muscle attachments.

I think your fears are probably groundless. They are probably the result of speculation and the real fear of how you would get along without your eyesight.
