Optic nerve decompression is a surgical procedure aimed at removing a portion of the bony canal (tunnel) which houses the optic nerve. The optic nerve is the “nerve of vision” and extends from the brain, through your skull, and into your eye. A portion of the optic nerve is enclosed in a rigid, bony tunnel as it exits the skull. Because of this, any condition which causes swelling or compression of the optic nerve at this location may lead to a loss of vision or blindness because there is no room or space for the nerve to expand. The goal of the optic nerve decompression surgery is to remove a portion of the bony optic canal, thereby relieving some of the pressure on the optic nerve. This procedure of optic nerve damage treatmentis done with the use of endoscopes (small rigid telescopes), allowing the Ophthalmologistto go through the nose and sinuses to perform this delicate surgery without any cuts to the face. In the following sections, we will review the indications, risks and benefits of endoscopic optic nerve decompression. Orbital decompression is the partial or complete removal of one or more, of the four walls of the orbit (eye socket). The common problems include some combination of thyroid disease, bulging of the eyes (exophthalmos), lid lag, retraction of the eye lids and double vision (diplopia). Optic nerve decompression is performed with or without orbital decompression, depending on the etiology of the optic neuropathy.
