title: Terson syndrome caused by intraventricular hemorrhage associated with moyamoya disease.
abstract: Terson syndrome was originally used to describe a vitreous hemorrhage arising from aneurysmal subrarachnoid hemorrhage. Terson syndrome can be caused by intracranial hemorrhage, subdural or epidural hematoma and severe brain injury but is extremely rare in intraventricular hemorrhage associated with moyamoya disease. A 41-year-old man presented with left visual disturbance. He had a history of intraventicular hemorrhage associated with moyamoya disease three months prior to admission. At that time he was in comatose mentality. Ophthalmologic examination at our hospital detected a vitreous hemorrhage in his left eye, with right eye remaining normal. Vitrectomy with epiretinal membrane removal was performed. After operation his left visual acuity was recovered. Careful ophthalmologic examination is mandatory in patients with hemorrhagic moyamoya disease.
