Abnormal Pupil Finding after an Orbital Floor Fracture in a Child

Purpose: Trauma to the pupillary fibers can occur during repair of orbital floor fracture resulting in a fixed and dilated pupil. The authors report, discuss, and propose an etiology of an abnormal pupil in a child with an orbital floor fracture before surgical repair. Methods: A case report is described. Results: Although the orbital fracture was repaired, anisocoria persisted 18 months after the initial trauma. Conclusions: Pupillary function must be assessed before surgical repair of an orbital floor fracture as damage of the pupillary fibers can occur secondary to the orbital floor fracture.
