Orbital Decompression Surgery

What is orbital decompression surgery?

Orbital decompression involves removal of some (one to three) of the four bony walls of the orbit to create more space for the inflamed orbital tissues and allowing backward movement of the eyes in the eye-sockets. Some orbital fat is also sometimes removed.

Orbital decompression is done to take the pressure off the optic nerve and allow recovery of sight, or to improve the cosmetic appearance. There are various surgical techniques. Sometimes an  incision is made at the outer angle of the eyelids and the scar rapidly fades into the natural creases. Sometimes the surgery is done endoscopically (up the nose).

What does orbital decompression surgery involve?

The surgery is performed under general anaesthetic and takes about 2 to 3 hours per eye. It involves admission to hospital for at least one night. You will be kept in hospital until you are safe to go home and comfortable enough to do so.
