title: Mastication induced retrobulbar hemorrhage.
abstract: Retrobulbar hemorrhage is a feared potentially sight threatening complication after orbital decompression surgery. We present a patient, 36 hours after surgery, while forcefully biting, suddenly developed a retrobulbar hemorrhage arising from the temporalis muscle causing an orbital compartment syndrome. Rapid intervention with canthotomy and cantholysis was associated with recovery of vision from absent light perception to 20/20. A mastication induced retrobulbar hemorrhage has not been previously described.
