Ischemic cerebrovascular disease has a high incidence and prevalence in Cuba, and it is the third cause of death in the country. A number of anatomical and clinical differences distinguish anterior from posterior circulation infarction. On certain occasions the distinguishing elements that aid in the topographic diagnosis of ischemic cerebrovascular disease are its neuro-ophthalmological manifestations. With the purpose of gaining insight into the current knowledge about the neuro-ophthalmological alterations associated to ischemic cerebrovascular disease, a bibliographic review was conducted based on the analysis of 69 digital information sources from the last five years. Cerebral circulation is generally divided into anterior and posterior. The main symptoms and signs of the stroke that affects anterior circulation are conjugate gaze deviation, altered saccades, homonymous hemianopsia, heminegligence and eyelid opening apraxia, whereas the alterations associated to posterior circulation involvement are nystagmus, eye movement and alignment abnormalities, and homonymous hemianopsia with macular preservation. It is concluded that ischemic cerebrovascular disease presents symptoms and signs related to both the afferent and the efferent visual pathways. Homonymous hemianopsia is the most common sign reported.
Key words: Cerebral circulation; ischemic cerebrovascular disease; neuro-ophthalmological manifestations; homonymous hemianopsia; eye movement disorder; nystagmus.
