Show PHOTO ESSAY Intracranial Displacement of the Eye After Blunt Trauma Zinat Miabi, MD, Nariman Nezami, MD, Mehran Midia, MD, and Ramin Midia, MD Abstract: A 67- year- old man fell from an agricul-tural vehicle and struck his right eye on a protruding element. Eight hours later, he was brought to the emergency unit of an ophthalmology hospital where examiners could not find the right eye and believed it to have been completely destroyed. However, CT disclosed that the eye, apparently still intact, had been displaced into the anterior cranial fossa through a fracture in the orbital roof. This is the first documentation of such a phenomenon. ( J Neuro- Ophthalmol 2009; 29: 311) A 67- year- old man fell accidentally from a tractor. His right eye struck a protruding part of the vehicle. He experienced massive bleeding from his right eye and a 3 to 5- minute period of unconsciousness. Eight hours later, he was brought to the emergency unit of an ophthalmology hospital where examiners could not find the right eye and believed it to have been completely destroyed. The orbit was irrigated and an upper eyelid laceration was repaired. Throughout 7 days of hospitalization and 7 days of partial bed rest at home, the patient complained of severe right frontal headache. CT ( Fig. 1) revealed that the right eye appeared to be intact and had herniated through a bony defect in the right orbit roof and substantially into the floor of the anterior fossa. As far as we know, there have been no case reports demonstrating trauma- induced intracranial dislocation of an intact eye. FIG. 1. A. Coronal CT shows the apparently intact right eye dislocated superomedially through a large right orbital roof defect. B. Sagittal CT shows that at least half of the eye is situated in the anterior cranial fossa. There is an associated anterior frontal lobe contusion. C. Axial CT shows that the herniation is partially through the ethmoid sinus.
