Abstract:
Objective:To analyze the characteristics of eye movement changes in patients with acute cerebral infarction characterized by dizziness or vertigo.Methods:The clinical data of 114 patients characterized by dizziness or vertigo in the Civil Aviation General Hospital from January 2021 to June 2022 were retrospectively analyzed. Among them, acute cerebral infarction was in 74 cases (acute cerebral infarction group), including anterior circulation infarction 32 cases, posterior circulation infarction 42 cases; benign paroxysmal positional vertigo (BPPV) was in 40 cases (BPPV group). The clinical manifestation and the results of videonystagmography (VNG) examination were recorded.Results:There were no statistical differences in the incidences of visual shaking, dysarthria and paresthesia between two groups ( P>0.05); the incidence of visual rotation in acute cerebral infarction group was significantly lower than that in BPPV group: 25.68% (19/74) vs. 100.00% (40/40), the incidence of limb weakness and walking instability were significantly higher than those in BPPV group: 29.73% (22/74) vs. 0 and 39.19% (29/74) vs. 0, and there were statistical differences ( P<0.01). The result of VNG examination showed that the abnormal incidences of eye movement and positional test in acute cerebral infarction group were significantly lower than those in BPPV group: 74.32% (55/74) vs. 100.00% (40/40) and 2.70% (2/74) vs. 100.00% (40/40), the abnormal incidences of gaze-holding test, without fixation test, randomly saccade test, smooth pursuit test and optokinetic nystagmus test were significantly higher than those in BPPV group: 10.81% (8/74) vs. 0, 21.62% (16/74) vs. 0, 45.95% (34/74) vs. 2.50% (1/40), 60.81% (45/74) vs. 5.00% (2/40) and 21.62% (16/74) vs. 0, and there were statistical differences ( P<0.01 or <0.05). There were no statistical differences in the incidences of visual rotation, visual shaking, dysarthria, walking instability and paresthesia between anterior circulation infarction patients and posterior circulation infarction patients ( P>0.05); the incidence of limb weakness in patients with anterior circulation infarction was significantly higher than that in patients with posterior circulation infarction: 50.00% (16/32) vs. 14.29% (6/42), and there was statistical difference ( P<0.01). The result of VNG examination showed there were no statistical differences in the abnormal incidences of eye movement, gaze-holding test, without fixation test, randomly saccade test, smooth pursuit test, optokinetic nystagmus test and position test between anterior circulation infarction patients and posterior circulation infarction patients ( P>0.05). Conclusions:The abnormal incidence of eye movements in patients with acute cerebral infarction is relatively high, and VNG examination can help reflect changes of the eye movement pathway in the brain.
