To evaluate the diagnostic value of eye movements and vestibular function tests in PCI patients.
Thirty-eight PCI patients and 31 patients with unilateral vestibular neuritis (UVN) were enrolled and underwent eye movement tests and vestibular function tests (spontaneous nystagmus [SN], head-shaking nystagmus [HSN]).
The rates of eye movement abnormality were 78.9% and 41.9% in PCI and UVN patients, respectively. The positive rate of SN and HSN were, respectively, 41.2% and 43.8% in cerebellar infarction patients, 33.3% and 66.7% in medullary infarction patients, and 100.0% and 86.2% in UVN patients. The horizontal direction of SN and HSN coincided with the affected side in cerebellar infarction patients, and the healthy side in UVN patients, which coincided with the healthy side and the affected side, respectively in medullary infarction patients. The horizontal direction of HSN was bidirectional nystagmus in 16.0% (4/25) of UVN patients.
Eye movement and vestibular function tests contribute to the early diagnosis of PCI. The horizontal direction of SN and HSN are consistently toward the affected side in cerebellar infarction patients and the healthy side in UVN patients, in contrast to medullary infarction patients, and deserve further investigations.
评估眼球运动和前庭功能测试在PCI患者中的诊断价值。
纳入38例PCI患者和31例单侧前庭神经炎（UVN）患者，进行眼球运动测试和前庭功能测试（自发性眼震[SN]、摇头眼震[HSN]）。
PCI患者和UVN患者的眼球运动异常率分别为78.9%和41.9%。小脑梗死患者中SN和HSN的阳性率分别为41.2%和43.8%，延髓梗死患者中分别为33.3%和66.7%，UVN患者中分别为100.0%和86.2%。小脑梗死患者中SN和HSN的水平方向与患侧一致，UVN患者中与健侧一致，延髓梗死患者中分别与健侧和患侧一致。16.0%（4/25）的UVN患者中HSN的水平方向为双向眼震。
眼球运动和前庭功能测试有助于PCI的早期诊断。与延髓梗死患者不同，小脑梗死患者中SN和HSN的水平方向始终朝向患侧，UVN患者中朝向健侧，值得进一步研究。
