Some strokes can cause unequal pupils.Īre there warning signs of a stroke that affect your eyes?Ī person should be concerned if they have the following symptoms: When the brain stem is affected, a patient may experience double vision since it can affect cranial nerves that control eye movements. When this is affected through stroke there may be impaired visuospatial function, impaired visual attention or deficits in visual recognition. There are certain areas in the brain which operate as perceptual segments of the visual pathway. When the carotid artery in the neck or in the head is blocked from a clot, this clot may spread to the artery supplying the retina and can cause vision loss. In a bilateral occipital lobe stroke, a patient may experience profound loss of vision in both eyes. Patients will notice missing areas in peripheral vision. Since the visual pathway goes through the cerebral hemisphere on each side, stroke affecting certain areas of the cerebral hemisphere will impact the visual pathway and produce visual field loss. 1, 2022) - The visual pathway is very long and goes from the eyes to the occipital lobe, which is the region in the cerebral hemisphere that processes vision.
