[Terson's syndrome. Subarachnoid hemorrhage combined with vitreous body hemorrhage].

Terson's syndrome consists of the combination of acute intracranial haemorrhage (most often an aneurysmal subarachnoidal haemorrhage) and profuse bleeding in the vitreous body of one or both eyes. The incidence is from 2% to 16% of patients with subarachnoidal haemorrhage. These patients are often confused in the early phase of their disease, and their decreased visual acuity is often not recognized. We describe findings in a patient recently seen in our department, with subarachnoidal haemorrhage and gross bleeding in the vitreous body of both eyes. We emphasize the importance of being aware of the syndrome, both in order to provide adequate nursing care, and to be able to perform early vitrectomy to restore visual function.
