Orbital Blowout Fracture and Orbital Emphysema caused by Nose Blowing.

A 76-year-old man presented with 1 day history of eyelid swelling and decreased vision on the left side. History reveals nose blowing the night prior to the occurrence of the symptoms. Initial examination of the left eye showed decreased visual acuity, increased intraocular pressure, and limited ocular motility with presence of air bubbles under the bulbar conjunctiva. Imaging studies showed medial orbital wall fracture with severe emphysema. The patient was observed for a week and no active surgical intervention was performed. Thereafter, spontaneous resolution of symptoms was observed. Eyelid swelling, dramatic improvement in visual acuity, intraocular pressure, and extraocular movements were noted.
