Pneumatic Retinopexy

This is used for simple detachments, with tears located superiorly, and not more than 1-2 clock hours in size.

The patient is not required to fast. Numbing drops are placed on the eye, and a retrobulbar injection is given. Freezing (cryotherapy) is placed around the tear, after which a small gas bubble is placed inside the eye. The patient is then positioned in such a way as to allow the gas to cover the tear.

Positioning is usually maintained for 5-7 days, after which normal positioning is allowed.
