Conditions which affect the structure or function of the pupil of the eye, including disorders of innervation to the pupillary constrictor or dilator muscles, and disorders of pupillary reflexes.

Conditions in which the pupil does not react normally to dilation and constriction. Signs of pupillary abnormalities originate from the pupil's shape, position, and response to stimulation.
