Rheinboldt M, Francis K, Parrish D, Harper D, Blase J. Terson syndrome in conjunction with ruptured intracranial aneurysm and penetrating intracranial injury: a review of two cases. Emerg Radiol. 2013;.
Terson syndrome, the presence of intraocular hemorrhage in the setting of acutely elevated intracranial pressure, was historically described in conjunction with acute subarachnoid hemorrhage; however, more recently, it has been associated with a gamut of intracranial pathophysiology ranging from blunt or penetrating injury to neurosurgical procedures. We describe two cases of profound intracranial injury, secondary to ballistic injury, and a ruptured intracranial aneurysm, in which posterior chamber ocular hemorrhage was noted on CT imaging. Though the outcome in such cases, as with ours, is often poor, the findings are germane to clinical care as the presence of Terson syndrome has been noted to be a negative prognostic factor in multiple clinical reviews. Additionally, clinical recovery can be impacted adversely by lasting visual deficits or retinal degradation in the absence of timely ophthalmologic intervention.
