The long ciliary nerves provide sensory innervation to the eyeball, including the cornea. In addition, they contain sympathetic fibers from the superior cervical ganglion to the dilator pupillae pupillÃ¦. musclehe sympathetic fibers to the dilator pupillae muscle mainly travel in the nasociliary nerve but there are also sympathetic fibers in the short ciliary nerves that pass through the ciliary ganglion without forming synapses.
