Objective To analyze the ophthalmologic characteristics caused by cerebral infarction and evaluate their diagnostic value of visual pathway diseases through vision field defects. Methods Retrospective analysis of 90 cases of cerebral infarction patients with ophthalmologic signs were performed. Ophthalmologic features and incidences , the main dangerous factors of cerebral infarction and vision field defects features were observed. Results A-mong all 90 patients with the corresponding eye symptoms, visual acuity decreased in 31 cases, vision field defects was in 28 cases,fundus arteriosclerosis in 25 cases,diplopia in 10 cases,nystagmus in 3 cases,ocular movement disorder in 5 cases and ptosis in 3 cases. Among 75 patients who took cervical vascular ultrasound , unilateral and bilateral internal carotid atherosis in 30 cases and 45 cases. Among 54 cases who received the digital subtraction angiography ( DSA) and/or ranscranial Doppler ultrasound ( TCD) , vertebral artery was abnormal in 42 cases, abnormal anterior cerebral artery( PCA) and middle cerebral artery( MCA) and posterior cerebral artery( PCA) in 16 and 33 and 6 cases, respectively. Conclusion Cerebral infarction may cause eye-related symptoms and distinctive vision field defects may assist to judge the position of visual pathway. Patients with cerebral infarction maybe first appear at the department of ophthalmology, so we should pay attention to it.%目的 分析脑梗死引起眼部症状的临床特点并评价视野缺损对视路病变的诊断价值.方法 回顾性分析90例脑梗死患者临床资料,观察其并发眼部症状的特点、发生率、主要危险因素、视野检查与脑梗死病变位置的关系.结果 90例脑梗死患者中视力下降31例、视野缺损28例,眼底动脉硬化25例、复视10例、眼球震颤3例、眼球运动障碍5例、上睑下垂3例.90例患者中75例经颈部血管超声检查显示30例单侧和45例双侧颈内动脉粥样硬化.经颅多普勒超声检查和(或)全脑血管数字减影检查的患者,椎动脉异常42例,大脑前动脉异常16例,大脑中动脉33例,大脑后动脉6例.结论 脑梗死常出现各种不同的眼部改变,特征性的视野改变有助于判定视路病变的部位,脑梗死患者可能首诊于眼科,应引起重视.
