The short ciliary nerves are nerves of the orbit around the
Structure
The short ciliary nerves are branches of the ciliary ganglion.[1] They arise from the forepart of the ganglion in two bundles connected with its superior and inferior angles. The lower bundle is the larger than the upper bundle. These split into between 6 and 10 filaments.
They run forward with the
They pierce the sclera at the back part of the bulb of the eye, pass forward in delicate grooves on the inner surface of the sclera, and are distributed to the ciliary muscle, iris, and cornea.
Function
The short ciliary nerves contain both
Clinical significance
Damage to the short ciliary nerve may result in loss of the pupillary light reflex,[2] or mydriasis.
