Prognostic significance of conjugate eye deviation in stroke patients.
We prospectively studied the prognostic significance of conjugate eye deviation in 80 patients with acute stroke and compared the 3-month mortality and disability of these patients to those of the Tilburg epidemiological study of stroke. Mortality of patients with conjugate eye deviation was higher (41%) than for the general stroke population (34%), but this difference was not statistically significant (p less than 0.179). Looking at mortality and disability together, we found the outcome of patients with conjugate eye deviation to be significantly worse (p less than 0.001). Deviation of the eyes occurred more frequently to the right (65%) than to the left (35%). In the patient group with eye deviation to the left, mortality was significantly higher (64%, p less than 0.001) than in the group with eye deviation to the right (25%); only two patients of the former group (n = 28) could return home. Compared to the Tilburg epidemiological study of stroke, the group with eye deviation to the left did significantly worse, both for mortality alone (p less than 0.001) and for mortality and disability together (p less than 0.001). The group with eye deviation to the right did significantly worse only for mortality and disability together (p less than 0.01). Our results indicate that conjugate eye deviation is a prognostic factor for poor short-term mortality and disability in stroke patients, especially when the eyes are deviated to the left.
