Long ciliary nerves

Dr Craig Hacking et al.

The long ciliary nerves are a group of nerves that branch from the nasociliary nerve in the intraconal space. Along with the short ciliary nerves, they supply sensation to the entire globe excluding the conjunctiva. Unlike the short ciliary nerves however, they bypass the ciliary ganglion and hence don’t contain parasympathetic fibres. There are 2-3 long ciliary nerves which carry somatosensory fibres as well as sympathetic fibres from the adjacent ICA, each entering the posterior globe separately to supply the dilator pupillae and sensation to the cornea.
