Terson's syndrome (TS) is a vitreous hemorrhage that develops in patients with subarachnoid hemorrhage (SAH) most frequently due to ruptured aneurysm. The reported incidence of TS has varied between 1.4 and 16.7%. Of 36 consecutive SAH patients that we treated, TS was diagnosed in 12 patients (33%). The reason that the incidence of TS in our patients series was much higher than previously reported was due to the use of a mydriatic agent to accurately diagnose TS and the examination of all 36 consecutive patients, including those with a high Hunt and Kosnik grade. In our study, the incidence of TS was significantly greater among patients with a higher grade of SAH according to a H & K classification, as noted in past reports (P-value＝0.0047<0.05). Additionally, the incidence of TS was greater in patients with a higher SAH grade according to the classification proposed by Fisher (P-value＝0.088>0.05). In this connection, we speculated that the mechanism of TS was the reflux of an abundance of blood drained into the orbital cavity via the Virchow-Robin space.
Long-term retention of blood in the vitreous body may cause cell damage and delay the start of rehabilitation. Therefore, early treatment is preferable.
