Ciliary ganglion

Dr Craig Hacking et al.

The ciliary ganglion is one of four parasympathetic ganglia of the head and neck. It receives parasympathetic fibres from the oculomotor nerve.

Gross anatomy

  • short ciliary nerves from the ophthalmic division of the trigeminal nerve which supply the ciliary body (for accommodation) and the sphincter papillae (for pupillary constriction)

Related pathology

  • pathology of the ciliary ganglion can produce a tonic pupil, where the pupil does not react to light and slowly accommodates
  • Adie syndrome: when a non-reactive, slowly accomodating pupil is associated with absent deep tendon reflexes and diaphoresis
