Inconsistent detection of subhyaloid hemorrhage in the globe using computed tomography

Excerpt

Subhyaloid hemorrhage is caused by cerebrovascular diseases including subarachnoid hemorrhage (SAH), intracerebral hemorrhage (ICH), arteriovenous malformation, and Moyamoya disease, and it is an emergency disease which leads to visual loss if treatment is delayed. Terson's syndrome, the occurrence of this SAH with subhyaloid hemorrhage, was reported first by Albert Terson in 1900 [1]. An abrupt increase in intracranial pressure is presumably responsible for this type of hemorrhage. This syndrome is not a rare finding among patients with SAH, but it is rare to detect this subhyaloid hemorrhage on computed tomography (CT) of the brain. In 1995, we reported a case of SAH with subhyaloid hemorrhage in the right globe demonstrated by CT of the brain and also estimated that the frequency of this phenomenon was approximately ∼1 of 1,000 patients with the diagnosis of SAH [2]. …
