In their article,1 Sinawat et al compared the success rate of pneumatic retinopexy (PR) when performed with 0.3 mL of air vs 0.3 mL of perfluoropropane. One of the factors investigated was the single-procedure reattachment rate. The perfluoropropane group was found to have a single-procedure reattachment rate of 73% compared with 60.3% for the air group. This result was not statistically significant, though there was a difference in the rate of success between the 2 groups, with a trend toward perfluoropropane being more efficacious. The air group (39.7%), however, required significantly more injections than the perfluoropropane group (27%), indicating that an inadequately sized bubble is typically delivered into the eye when treating with air, using their method.
