Although conjugate eye deviation (CED) on head CT has been described in patients with acute stroke, the incidence in other patient groups remains unknown. The aim of this study was to determine the frequency of eye deviation on head CT in non-stroke patients compared to patients with acute stroke symptoms.
Three groups of patients were identified retrospectively: emergency department (ED)/inpatients undergoing head CT for non-stroke symptoms (group 1), stroke patients receiving intravenous tPA (group 2), and stroke patients undergoing intra-arterial therapy (group 3). The presence on head CT of CED, lone eye deviation (LED), and skew deviation (SD) and the angle of deviation were recorded. The NIHSS score was recorded for groups 2 and 3.
CED was present in 17 (14%) of 120 Group 1 patients, 17 (36%) of 47 group 2 patients, and 28 (50%) of 56 Group 3 patients (p < 0.0001). Mean deviation of CED in groups 1, 2, and 3 was 19(o) (range 7-36(o)), 25(o) (range 6-67(o)), and 27(o) (range 11-56(o)), respectively (p = 0.024). LED was seen in 42 (35%) of group 1, 7 (15%) of Group 2, and 2 (4%) of group 3 patients (p < 0.0001). There was no significant difference in SD among groups (p = 0.37). CED was associated with a higher National Institutes of Health Stroke Scale (NIHSS) score among stroke patients (p = 0.0008).
CED is common in patients with acute stroke. Such deviation may be seen in non-stroke patients, but less commonly and with lesser degrees of deviation.
尽管在急性卒中患者的头部 CT 上已经描述了共轭眼偏斜（CED），但在其他患者群体中的发生率尚不清楚。本研究的目的是确定与急性卒中症状患者相比，非卒中患者头部 CT 上出现眼偏斜的频率。
回顾性地确定了三组患者：因非卒中症状而行头部 CT 检查的急诊/住院患者（第 1 组）、接受静脉 tPA 治疗的卒中患者（第 2 组）和接受动脉内治疗的卒中患者（第 3 组）。记录头部 CT 上存在的 CED、单眼偏斜（LED）和斜偏（SD）以及偏斜角度。记录第 2 组和第 3 组的 NIHSS 评分。
第 1 组 120 例患者中有 17 例（14%）存在 CED，第 2 组 47 例患者中有 17 例（36%），第 3 组 56 例患者中有 28 例（50%）（p < 0.0001）。第 1、2 和 3 组的 CED 平均偏斜度分别为 19°（范围 7-36°）、25°（范围 6-67°）和 27°（范围 11-56°）（p = 0.024）。第 1 组有 42 例（35%）患者存在 LED，第 2 组有 7 例（15%），第 3 组有 2 例（4%）（p < 0.0001）。三组之间的 SD 无显著差异（p = 0.37）。CED 与卒中患者更高的国立卫生研究院卒中量表（NIHSS）评分相关（p = 0.0008）。
CED 在急性卒中患者中很常见。这种偏斜也可能见于非卒中患者，但较少见，且偏斜程度较轻。
