A 47-years old Korean farmer was first visited our department in Nov. 19, 1969 with complaining of proptosis, lateral deviation of eye ball and visual disturbance of 5 years duration.
The onset was insidious. Past and family history were not contributory.
On examination, right eye was within normal limit. The left eye was markedly proptotic (about 10 mm of exophthalmos) and displaced out-and downward. The vision of the left eye was L.P.. The ocular motility was slightly limited to all direction. Pupil was normal size and poorly reacted to light. Funduscopic examination revealed pale and slightly excavated in disc. X-ray of chest, skull and optic foramen showed normal.
On Nov. 22,1969 author adopted the Kronlein´s approach and excised a well capsulated oval mass situated within the muscle cone, which attached to optic nerve. The tumor mass showed soft, dark reddish color of surface measuring 2X2 X15 cm and its cut surface disclosed sponge like appearance. Histologically the section from tumorous mass showed many large cavernous spaces separated by connective tissue. The newly formed cavernouus space was for the most part lined by a ,single layer of endothelium and in part contained with red cell. We confirmed a diagnosis of cavernous hemangioma of the orbit in pathologic study.
It was suggested that early loss of vision was caused by optic atrophy due to direct pressure of optic nerve by the tumor mass.
A review of literature of recent years related to cavernous hemangioma of orbit was added.
