Subperiosteal Orbital Hemorrhage: An Unusual Complication During Labor

Subperiosteal orbital hemorrhage in the postpartum period has been rarely reported. The authors herein present a female patient who developed acute-onset vertical diplopia, proptosis, mild retro-orbital pain, and restriction of upgaze immediately after labor. Neuroimaging revealed a subperiosteal hematoma along the right orbital roof. Diplopia, motility limitation, and retro-orbital pain gradually resolved in the following weeks. Subperiosteal orbital hematomas are a rare complication of labor, with only 12 cases reported so far. They result from straining during labor, which increases central and orbital venous pressure by means of the Valsalva-maneuver. In order to evaluate ocular motility and exclude optic nerve compression, an urgent ophthalmological examination is required.
