Adies Pupil

A Pupillary abnormality characterized by a poor Pupillary Light reaction, reduced accommodation, Iris sector Palsies, an enhanced Pupillary response to near effort that results in a prolonged, "tonic" Constriction, and slow Pupillary redilation. This condition is associated with injury to the postganglionic parasympathetic innervation to the Pupil. (From Miller et al., Clinical Neuro-Ophthalmology, 4th ed, pp492-500)
