The optic strut is a bony structure of the Skull base.
Historical background
The optic strut was first described by Jefferson in 1936 as the sphenoid strut[^1].
Anatomy
The optic strut is a bony projection that separates the Optic nerve from the Internal carotid artery. It is a narrow column of bone that connects the body of the Sphenoid bone to the ala minor ossis sphenoidalis, which corresponds to the medial inferior aspect of the Anterior clinoid process[^2].
