I had a vitrectomy for a macular hole in my right eye about five or six years ago. They injected air into my eye during the surgery, but until now, there are still a few small air bubbles that haven’t gone away. Sometimes they hide somewhere in my eye and I can’t see them, and sometimes they come out. Is this bad for my eyes? Will it damage my retina or something else? Why does this happen? Does anyone else have this problem? Please let me know if you have the same experience as me, thank you.
