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

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.
