During pneumatic 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 retina.
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 quickly.
The hardest part of the recovery is keeping the gas bubble in the right place until a seal forms around the tear in the retina.
Contact your doctor right away if you notice any signs of 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.
Pneumatic retinopexy reattaches the retina most of the time.
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 less likely.
The most frequent problems from pneumatic retinopexy include:
Although they do not occur very often, other complications include:
Pneumatic retinopexy can be done on an outpatient basis.
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 decision.
You may need more than one surgery to reattach the retina if scar tissue from the first surgery grows over the surface of your retina.
