Abstract:
AIM:To explore the related factors of cerebral visual field defect after ischemic stroke and its impact on its long-term prognosis. METHODS: A retrospective study was conducted on patients with ischemic stroke admitted to the hospital from January 2021 to July 2023. Visual field examination was performed 7 d after onset, and patients were divided into cerebral visual field defect group and non-cerebral visual field defect group according to whether cerebral visual field defect occurred. Demographic information and clinical indicators were collected from both groups, and multivariate Logistic regression analysis was performed to identify factors associated with cerebral visual field defect after ischemic stroke. After discharge, a 2-year follow-up was conducted to calculate the number of poor prognosis, recurrence, and death cases to evaluate long-term prognosis.RESULTS:Among 218 patients with ischemic stroke, according to the visual field examination, 54 patients were in cerebral visual field defect group(incidence rate was 24.8%, 32 males and 22 females, mean age was 63.81±5.78 y)and 164 patients were in non-cerebral visual field defect group(95 males and 59 females, mean age was 62.78±6.01 y). There were no significant differences in gender, BMI, education level, smoking history, drinking history, diabetes, hypertension, hyperlipidemia, time from onset to admission, and type of infarction between the two groups(all P>0.05). There were significant differences in age, atrial fibrillation, degree of neurological deficit, infarct location and infarct volume between the two groups(all P<0.05). Multivariate Logistic regression analysis showed that the risk factor of cerebral visual field defect after ischemic stroke was the degree of neurological deficit at admission(OR: 5.106; 95%CI: 1.034-25.205), infarct location [parietal lobe(OR: 5.760; 95%CI: 1.643-20.194); temporal lobe(OR: 6.437; 95%CI: 1.591-26.036); occipital lobe(OR: 8.998; 95%CI:1.748-46.319)],infarct volume(OR: 5.123; 95%CI: 1.318-19.906). The poor prognosis and recurrence rate in the cerebral visual field defect group were higher than those in the non-cerebral visual field defect group(both P<0.05), and there was no difference in mortality rate between the two groups(P>0.05).CONCLUSION:The occurrence of cerebral visual field defects after ischemic stroke is closely related to the severity of the condition, infarct location and infarct volume infarction, and can lead to poor long-term prognosis. Therefore, prevention and treatment should be strengthened.
