Objective: To present a patient with Terson syndrome and to propose a mechanism for vitreous hemorrhage.
Design: Observational case report.
Participant: A 50-year-old woman with subarachnoid hemorrhage and unilateral vitreous hemorrhage.
Methods: Detailed examination with fluorescein angiography and funduscopy.
Main outcome measures: Site of dye leakage on fluorescein angiography in the eye with vitreous hemorrhage.
Results: 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.
Conclusions: 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.
