Parasympathetic fibers travel with cranial nerve III, the oculomotor nerve, to innervate the circular layer of muscle of the eye (sphincter pupillae). Damage to this nerve typically manifests itself as mydriasis, because the sympathetic supply to the pupil, which causes mydriasis, remains unaffected, and therefore unopposed.

One pupil is dilated and unreactive, while the other is normal (in this case, the right eye is dilated, while the left eye is normal in size). This could mean damage to the oculomotor nerve (cranial nerve number 3, CN III) on the right side, or indicate the possibility of vascular involvement. Both pupils are dilated and unreactive to light.

[1] It is frequently seen in females with absent knee or ankle jerks and impaired sweating.
