The pathway of pupillary constriction begins at the Edinger-Westphal nucleus near the occulomotor nerve nucleus. The fibers enter the orbit with CNIII nerve fibers and ultimately synapse at the cilliary ganglion. Sympathetic innervation leads to pupillary dilation.
Miosis means excessive constriction (shrinking) of your pupil. In miosis, the diameter of the pupil is less than 2 millimeters (mm), or just over 1/16th of an inch.
