long ciliary nerve

long cil·i·ar·y nerve

[TA]
one of two or three branches of the nasociliary nerve, which bypass the ciliary ganglion, supplying postsynaptic sympathetic fibers for the dilator pupillae muscle and sensory fibers for the ciliary muscles, iris, and cornea.

From here, they divide into two long ciliary nerves to reach the iris dilator muscle.
Syndromes in maxillofacial injuries
Sympathetic fibres travel via the nasociliary nerve and the long ciliary nerves until they reach the ciliary body and dilator pupillae muscle.
Characteristics of normal and abnormal pupils--part 1
The sensory nerves reach the eye through the nasociliary branch of the ophthalmic nerve [15], which branches typically into two long ciliary nerves, one nasal and the other temporal, which course directly to the posterior pole of the eye, and a communicating branch carrying sensory fibers to the ciliary ganglion [1].
Corneal sensitivity in keratoconus: a review of the literature
The third-order or post-ganglionic neuron travels on the surface of the internal carotid artery into the intracranial space and cavernous sinus to arrive at the iris dilator through the long ciliary nerves. Damage can happen anywhere along this pathway and a series of pharmacological tests can be performed to determine whether the lesion is pre- or post-ganglionic.
