Terson's syndrome in subarachnoid haemorrhage

Comparison of CT and clinical findings of Terson's syndrome in 121 patients: a 1-year prospective study

“…Further, the case reports that exist represent only those patients with the most difficult intraocular hemorrhages. 2,13,15,24 Typical CT findings in our study were unchanged from earlier reports. 15,24,30 Because CT features were often subtle, the sensitivity remained only fair.…”

“…2,13,15,24 Typical CT findings in our study were unchanged from earlier reports. 15,24,30 Because CT features were often subtle, the sensitivity remained only fair. As reformatted slice thickness was 2.5-5 mm, CT missed some cases of subhyaloid hemorrhage that occupied widths less than a slice.…”

Anterior Communicating Artery Aneurysm Related to Visual Symptoms

“…In the previous review of literature, Terson's Syndrome was defined as symptoms where visual impairment was generated by intra-globe hemorrhage due to ruptured anterior communicating artery aneurysm. Though the mechanism of post-rupture bleeding into the eyeball has not been fully explained, what is considered the most convincing is that due to sudden increase in venous pressure with the blockage in venous flow to the eyeball caused by increased intracranial pressure, small veins are ruptured and as a result cause hemorrhage 18,23,27) .…”

“…Visual loss due to ruptured intracranial aneurysms is, in most cases, explained by Terson's Syndrome, the condition that the visual symptoms appear from bleeding in the subhyaloid or in the cornea due to the rupture of intracranial aneurysm. Nevertheless, the precise pathological mechanism of such rupture extending the bleeding towards the eyeball and its surrounding area has yet to be examined and identified 18,23,27) .…”
