Or, it can be a symptom of a stroke that's already occurred. Vision complications due to a stroke depend on where the stroke occurs. The majority of visual processing occurs in the occipital lobe, in the back of the brain. Most strokes affect one side of the brain. If the right occipital lobe is injured, the left field of vision in each eye may be affected. A stroke that affects the left occipital lobe may disturb the right field of vision in each eye. Rarely, both sides of the brain are affected, but this can result in blindness.
Emotional and behavioral changes are a common effect of stroke. Not only can stroke impact one's mood and outlook, but the area of the brain injury and chemical changes may have significant effects on the brain. The brain is an extremely complex organ that controls various body functions. If a stroke occurs and blood flow can't reach the region that controls a particular body function, that part of the body won't work as it should. If the stroke occurs toward the back of the brain, for instance, it's likely that some disability involving vision will result.
