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.
