• Neurofibromatosis has been reported to involve the eye and orbit by causing irregularities of the sphenoid and other facial bones and enlargement of the foramina. To our knowledge, abnormalities of the orbital floor, however, have not been attributed to this disease in the literature until now.

Two patients with neurofibromatosis had orbital floor involvement. Multiple neurofibromas eroding the orbital floor threatened vision in one patient. The other case, seen after trauma, had a condition simulating that of a blow-out fracture.

Diagnostic workup with adequate roentgenography, especially tomography, helped to establish the diagnosis. We believe this is of importance in modifying the surgical approach, obviating the need for surgical intervention at times.
