The short ciliary nn. originate from the ciliary gangion in the orbit and travel to the eyeball. They contain:
general sensory fibers that bring sensation back from the eyeball through CN V1
postgangionic parasynpathetic fibers that innervate the ciliary m. and sphincter pupillae
postganglionic sympathetic fibers that innervate the dilator pupillae and the superior tarsal m.
