A 61-year-old male initially presented to the ophthalmology department complaining of sudden visual loss. Fundus photography and ultrasonography followed by computed tomography identified Terson’s syndrome caused by subarachnoid hemorrhage (SAH). Cerebral angiography revealed a dissecting aneurysm of the left vertebral artery. Other than obtunded visual acuity, his neurological examination was normal and he denied any headache. He was treated conservatively with pain and blood pressure control. He complained of headache associated with rerupture of the aneurysm on day 5. The patient died of rerupture on day 14. The clinical course of this patient indicates that Terson’s syndrome may occur without sudden increase of intracranial pressure. Terson’s syndrome may occur as a rare initial clinical sign of SAH caused by ruptured cerebral aneurysm.
