What is optic canal?

The optic canal is a small opening located in the lesser wing of the sphenoid bone, which is a bone located at the base of the skull. The canal is located just behind the eye socket (orbit) and allows for the passage of the optic nerve (cranial nerve II) and the ophthalmic artery.

The optic canal is a crucial structure as it provides a protective pathway for the optic nerve, which is responsible for transmission of visual information from the eye to the brain. Any damage or compression of the optic canal can result in impaired vision or blindness.

In addition to housing the optic nerve, the optic canal also contains the ophthalmic artery, which is the first branch of the internal carotid artery and supplies blood to the structures of the eye.

Any conditions or injuries affecting the optic canal, such as fractures of the sphenoid bone or tumors compressing the optic nerve, may require medical intervention to preserve vision and prevent further complications. Treatment options may include surgery to decompress the canal or remove any obstructions.
