Terson Syndrome
The association of vitreous hemorrhage and acute intracranial hemorrhage, or Terson syndrome, has been recognized since 1900. This is reported in 3-14% of individuals with subarachnoid hemorrhage. The mechanism is thought to be related to the rapid increase in intracranial pressure with intracranial aneurysmal rupture which is transmitted through the venous system. Consequences can be severe, including vision loss and retinal detachment, and microsurgical vitrectomy can be performed. A fundoscopic exam is thus an important part of assessing a patient with subarachnoid hemorrhage.
