Pneumatic retinopexy is a procedure used to repair certain types of retinal detachment. A special gas (C3F8 or SF6) is placed in the eye. The gas serves to tamponade the tear, preventing more fluid from going under the retina. It also helps push the retina back onto the wall of the eye. The tear is then sealed with either laser treatment or freezing treatment (Cryo-therapy). If the retina fails to reattach further procedures such as scleral buckling or vitrectomy may be needed.
