Please use the search feature and archives and read about gas and air bubbles in they eye. There are informative and extensive. I am assuming you are talking about air inside the eye for retina detachment or macular surgery?

I see a faint white mist circle in the center of my eye, not the gas bubble, what wondering what causing it ? I did a search on the internet and on here and couldn't find an explanation.
And yes it for a retina detachment
