CONT

Optic nerve sheath fenestration is an operation which is performed to reduce the swelling in the optic nerves in order to protect the eyesight. It involves a surgeon making a small window in the tough coating surrounding the optic nerve, called optic nerve sheath. This allows the fluid around the nerve to be released. The excess fluid escapes and harmlessly absorbs into surrounding tissues. This reduces the swelling in the optic nerve on the side that the procedure is performed.
