Penetrating orbital injuries may involve intracranial structures as well. We report an unusual case of permanent visual loss, temporary complete ophthalmoplegia, and penetration of the internal carotid artery following penetrating nail injury. CT scanning and arteriography are important diagnostic tests to consider prior to removal of an orbital foreign body. This case also demonstrates the importance of delaying repair of traumatic ptosis and ophthalmoplegia.

A 48-year-old female was fitted with hard contact lenses and lost the right lens the next day. She was asymptomatic for 62 months but then presented with a painful mass in the right superonasal orbital quadrant. ⋯ Five months later the contact lens was found in the right upper fornix. This case emphasizes the importance of a thorough ocular examination, including double eversion of the lids and sweeping the fornices of patients with unidentified periocular masses or pain.
