ciliary nerve

Either of two nerves, the long ciliary nerve and the short ciliary nerve, that carry sensory axons and postganglionic sympathetic fibers that innervate the ciliary body, iris, and cornea of the eye. The long ciliary nerves are branches of the nasociliary nerve; the short ciliary nerves come from the ciliary ganglion and also contain preganglionic parasympathetic axons.

The fourth neuron leaves the ciliary ganglion and passes with the short ciliary nerves to innervate the sphincter pupillae (see Figure 2, page 54).
Sympathetic fibres travel via the nasociliary nerve and the long ciliary nerves until they reach the ciliary body and dilator pupillae muscle.
If one (or both) pupils are poorly reactive to light, this localises the lesion to the parasympathetic pathway (brainstem, third nerve, ciliary ganglion, short ciliary nerves and iris sphincter); in this scenario, the anisocoria increases in bright light conditions.
The cornea is innervated by a network of nerve endings located primarily in the anterior stroma, and is supplied by long ciliary nerves originating from the trigeminal nerve.
