These illustrations are adapted from the original illustration by Patrick Lynch released on Creative Commons Attribution 2.5 License 2006 and available on Wikimedia commons here.
A number of changes were made:
- optic nerve made lighter to distinguish from oculomotor nerve
- supply to superior oblique muscle removed (this is supplied by the trochlear nerve, not the oculomotor nerve)
- ciliary ganglion simplified
- superior oblique passes under superior rectus (modified by Anka Friedrich here)
