Adie pupil

Adie pupil (also known as tonic pupil) is caused by idiopathic degeneration of the ciliary ganglion, which sometimes occurs following a viral or bacterial illness. It is usually unilateral and typically affects young females 1.

Adie pupil represents a large dilated "tonic pupil", which does not constrict to bright light but can slowly accommodate to near objects, thereby demonstrating light-near dissociation. It is part of the classic triad called Adie syndrome
