The optic strut: an easily overlooked structure that might cause vision loss

The OS is a bony structure separating the superior orbital fissure, optic canal, and internal carotid artery. OS mucocele-induced pressure elevation and inflammation can damage the optic nerve and cause vision loss. Prompt surgical resection and optic nerve decompression are critical for preserving visual function in patients with space-occupying lesions around the optic canal.
