Terson's syndrome: Not a prognosticating factor of aneurysmal subarachnoid hemorrhage

ABSTRACT

Terson's syndrome has been implicated by previous studies as a strong predictor of poor outcome of patients with subarachnoid hemorrhage. There was even a recommendation to place patients with the syndrome in the next less favorable category. Hence this study was designed to provide a general profile of patients with Terson's syndrome and investigate whether the syndrome correlates with poor outcome. This study was done using a prospective cohort of patients seen at the Philippine General Hospital pay and charity wards from July 1, 1999 to June 30, 2000 diagnosed to have aneurysmal subarachnoid hemorrhage. Detailed ophthalmological examination was done and data were collected using a standard database. Patients were then followed up at 2 weeks, 1 month and 3 months to determine outcome (using Glasgow Outcome Score). Data collected were subjected to univariate analysis using chi square and/or Fisher test to determine significant correlation of variables with Terson's syndrome and to determine significance of Terson's syndrome as a predictor of poor outcome. A total of 52 patients were included in the study. The general demographic profile of patients with Terson's syndrome was comparable to that of the study population. The frequency of Terson's syndrome was 13.4 percent. There were no statistically significant differences in outcomes among patients with and without Terson's syndrome. However, positive correlation between laterality of Terson's syndrome with the side of aneurysm was shown. Although results were not significant, funduscopic examination remains to be warranted as an important part of diagnostic work-up of aneurysmal subarachnoid hemorrhage patients. When present, the laterality of Terson's syndrome may give a clue to the presence and side of the aneurysm.
