Orbital neurofibromas are uncommon
in adults, accounting for approximately 1%-3% of all space occupying lesions of
the orbit. The complex anatomy of the orbital region, with the pronounced
vulnerability of its neurovascular structures, requires particular surgical
precautions. Neuronavigation, as a high-tech device for intraoperative safety,represents a valuable option for the confined orbital space. However, the
application of neuronavigation in orbital surgery has been rarely reported. The
authors present a case report of a 32-year-old female with an isolated
localized neurofibroma surgically approached by intraoperative navigation and a
review of the literature.
A 32-year-old female presented with
a 2-year history of left upper lid swelling and progressive onset of proptosis
and double vision (Figure 1). She had no family history of neurofibromatosis.
Ophthalmologist’s examinationrevealed a decreased visual acuity 7/10 associated with ptosis, unilateral
exophthalmos with restricted eyeball movement on upward and lateral gaze in the
left eye. The visual field examination was normal.
