I am 3 months post retinal detachment surgery with c3f8 gas bubble.I am not seeing anymore gas bubble,the bubble was completly gone after 8 weeks.Sometimes I am still able to see tiny black dots that come and go away.My question is,are this black dots leftover gas bubbles or vitreous floaters.I had a vitrectomy and a buckle done.I went to my surgeon and said that bubble is gone,but somehow im not convince.My job requires flying..please an answer would be great,thank you
