A 50 year-old man suffered
from right decreased vision. He gave a 4-year history of progressive left
proptosis which was attributed to a retrobulbar mass of unknown histology.
The reduced vision was caused by a dense cataract and there was no relative
afferent pupillary defect. A repeat CT scan showed a retrobulbar mass
lateral to the optic nerve and there was no significant growth when compared
with the scan taken 3 years ago. He underwent a successful left
phacoemulsification and implant with good vision (6/9 without glasses).
Excision of the retrobulbar mass was suggested but declined by the patient
because of the risk of visual loss. In view of the history and the
radiological appearance, the retrobulbar mass was likely to be a cavernous
Left axial proptosis and dense
CT scan shows a well-circumscribed
retrobulbar mass lateral to the optic nerve.
