Transient loss of vision after carboxytherapy, what should I do?

Hi, 
 This is concerning. In 16 years of treating with carboxytherapy, I have never seen anything like this. Proper technique delivers a very small amount of CO2 in the very superficial layers of the skin outside the orbital bone which is very easy to do. Your situation sounds like the technique used was not correct, there should never be any carboxy that gets anywhere near the eyeball itself. I would definitely consult an eye doctor immediately.
