Abstract: Objective To evaluate the clinical features among stroke patients whose initial symptom werevisual loss or/and visual fields defect.Methods a retrospective study was used to analysis patients with initial visual disturbancediagnosed as stroke in department of neurology, Beijing Tongren Hospital from Jan. 2008 to Dec.2009.Results Fifteen patients were included in this study. There were 11 males and 4 females. Themean age is 55±14years. The initial manifestation included bilateral visual loss sequently, suddenmonocular visual loss, simultaneous bilateral visual loss, homonymous hemianopia defects. Thediagnosis included moyamoya disease(n=2), occlusion of the internal carotid artery(n=1), cerebralvascular malformation(n=1) anterior vascular stroke(n=1) and posterior vascular stroke(n=10).Among the posterior vascular stroke patients, seven cases were unilateral or bilateral occipitaland temporal lobes infarction, one top of the basilar artery syndrome, two cases were brain steminfarction.Conclusion The monocular visual disturbance is a topical sign of carotid artery ischemic. Thesudden bilateral visual loss was always attribute to vertebrobasilar system embolism. Some visualaura might be the early stage of devastating progressed posterior cerebral vascular disease.【Key Words】 Cerebral vascular disease; Visual disorders; Visual fields; Hemianopsia
