Abstract
A tonic pupil, without other features of an oculomotor neuropathy, is due to a lesion in the ciliary ganglion or short ciliary nerves. Here, we present a case of a tonic pupil in a woman with radiation-treated adenoid cystic carcinoma of the nasopharynx with perineural spread and skull base involvement. This a rare case of a tonic pupil caused by direct invasion of the ciliary ganglion or postradiation effects.
