Addendum: This last MRI, they asked if I had ever done any metal grinding, or been treated for foreign objects in the eye. (Answer to both was YES)
It was long enough ago, that they did not think it was a concern, or they would have x-rayed or CT first to make sure no metal fragments were going to tear their way out of my eyes!
