- Short ciliary nerves refer to the nerves that are accompanied by the long ciliary nerves and pierce the sclera to provide innervation to the ciliary body, cornea, and iris.

The short ciliary nerves are nerves of the orbit around the eye. They are branches of the ciliary ganglion. They supply parasympathetic and sympathetic nerve fibers to the ciliary muscle, iris, and cornea. Damage to the short ciliary nerve may result in loss of the pupillary light reflex, or mydriasis.

Where do ciliary nerves synapse?
Presynaptic parasympathetic signals that originate in the Edinger-Westphal nucleus are carried by cranial nerve III (the oculomotor nerve) and travel through the ciliary ganglion. Postsynaptic fibers from the ciliary ganglion form the short ciliary nerves.
The long ciliary nerves are 2-3 [1] nerves that arise from the nasociliary nerve (itself a branch of the ophthalmic branch (CN V 1) of the trigeminal nerve (CN V)). They enter the eyeball to provide sensory innervation to parts of the eye, and sympathetic visceral motor innervation to the dilator pupillae muscle.
Apr 25, 2016 · The ciliary ganglion lies temporal to the ophthalmic artery, inbetween the lateral rectus and optic nerve. It is approximately 1.5-2.0 cm (15-20 mm) posterior to the globe and 1.0 cm (10 mm) anterior to the Annulus of Zinn and the superior orbital fissure. Image credit: Wikipedia.
The short ciliary nerves find their way to the sphincter muscle following the short ciliary arteries and finally through the subchoroidal space between sclera and choroid, where they are vulnerable to photocoagulation of retina and choroid.
Definition. The branches of the ciliary ganglion are the short ciliary nerves. These are delicate filaments, from six to ten in number, which arise from the forepart of the ganglion in two bundles connected with its superior and inferior angles; the lower bundle is the larger.
Oct 30, 2023 · The ciliary ganglion then gives off short ciliary nerves (i.e. postganglionic fibers) that innervate the ciliary body. There is scarce evidence that the ciliary body receives some sympathetic innervation via the superior cervical ganglion that inhibits the accommodation reflex.
