Pneumatic retinopexy is an effective
surgery for certain types of
retinal detachments. It is usually an
outpatient procedure done with
retinopexy, the eye doctor (ophthalmologist) injects a gas bubble
into the middle of the eyeball. Your head is positioned so that the gas bubble
floats to the detached area and presses lightly against the detachment.
The eye doctor then uses a freezing probe (cryopexy) or laser
beam (photocoagulation) to seal the tear in the
The bubble remains for about 1 to 3 weeks to help flatten the
retina, until a seal forms between the retina and the wall of the eye. The eye
gradually absorbs the gas bubble and the extra fluid that had been in your eye.
Recovery from pneumatic retinopexy
takes about 3 weeks. The local anesthetic affects only the eye and wears off
The hardest part of the recovery is keeping the gas
bubble in the right place until a seal forms around the tear in the

complications after surgery, such as:
The location and size of a tear in
the retina determines whether pneumatic retinopexy can be used. Pneumatic
retinopexy can be useful when:
The break must be in the upper half of the eyeball for
pneumatic retinopexy to be practical. You have to be able to position your head
so that the break and the bubble are at the highest point. If the break was on
the bottom of the eyeball, you would have to stay upside down during your
recovery, which would not be practical.

Chances for good vision after surgery are higher if the
macula was still attached before surgery. If the
detachment affected the macula, good vision after surgery is still possible but

The success of pneumatic
retinopexy depends on keeping the gas bubble against the retina until it
flattens. This will require you to hold your head and eye in the proper
position for long periods of time. Do not have the procedure if a medical
condition or other situation will make you unable to stay in the right
position for the time required.
There are a
few ways to repair a retinal detachment. The chance that each surgery type can
help restore good vision varies from case to case. The cause, location, and
type of detachment usually determine which surgery will work best. Other
conditions or eye problems may also play a role in the
