A rare, neurological, unilateral, or bilateral disorder characterized by the pupil's parasympathetic denervation so that it’s abnormally dilated. This leads to poor light but tonic near constriction. It is caused by postganglionic pupillomotor damage resulting in sluggishness, decreased deep tendon reflexes, brisker near reactions, and segmental responses to light.
