I am a triathlete and a marathon runner. I had a detached retina approximately three weeks ago, with the buckle surgery and a 1/3 gas bubble of C3F8 gas inserted. Everything is healing nicely, no pain, slight redness nothing major, I have full field of vision back its just blurry through the gas bubble. I have been biking, not running MD said wait the full four to five weeks til I run. He said I can swim after 4 weeks. Just wondering about this gas bubble. I want to return to racing but the bubble is still bouncing around in the bottom of my eye. And if anyone else you have treated has been a triathlete and/ or marathon runner and their outcomes? I know everyone is different.
