Objective: To evaluate whether air is as effective as perfluoropropane gas in treating rhegmatogenous retinal detachment by pneumatic retinopexy.
Methods: In a double-blind, randomized, clinically controlled noninferiority trial, eligible patients were randomized into 2 treatment groups by using block randomization and treated by pneumatic retinopexy using filtered air or perfluoropropane gas.
Main Outcome Measures: Retinal reattachment rate and final visual recovery.
