Terson syndrome: a case report suggesting the mechanism of vitreous hemorrhage.

Abstract

To present a patient with Terson syndrome and to propose a mechanism for vitreous hemorrhage. Observational case report. A 50-year-old woman with subarachnoid hemorrhage and unilateral vitreous hemorrhage. Detailed examination with fluorescein angiography and funduscopy. Site of dye leakage on fluorescein angiography in the eye with vitreous hemorrhage. Fluorescein angiography showed the leakage site at the margin of the disc in the eye with vitreous hemorrhage after the vitreous hemorrhage had been removed. The damage to peripapillary tissues demonstrated by fluorescein leakage suggests that intracranial hypertension affects peripapillary structures through the intervaginal space of the optic nerve sheath.
