Pneumatic Retinopexy

In pneumatic retinopexy, a gas bubble is injected into the vitreous cavity. As the bubble rises, it presses the retina against the back wall of the eye. The retina specialist will then use laser therapy or cryotherapy to seal the retina in place.

The bubble is usually absorbed by the body within one to three weeks. Until the bubble reabsorbs, you may notice the bubble shifting during eye movement. With this procedure you may need to hold your head in one position in order for the retina to be reattached.
