title: Postoperative mydriasis after repair of orbital floor fracture.
abstract: Mydriasis after operative repair of orbital floor fracture has been attributed to manipulation of the inferior oblique muscle. We treated two patients with mydriasis, one with an isolated mydriatic pupil and the other with a tonic pupil, which followed posterior orbital floor injuries and repair. The posterior location of the fractures suggests that surgical manipulation of or near the ciliary ganglion may account for these phenomena. Patients should be warned before posterior orbital floor repair about possible mydriatic or tonic pupils as a complication.
