What Happens to Your Vision During a Stroke

A stroke can be defined in a variety of ways. Including changes related to vision.

Since the visual pathway (that is, the path of nerve impulses through which a person sees) is very long and passes through certain areas of the brain, a stroke can also affect it.

For example, a person may notice that he has stoppedsee some areas using peripheral vision (that is, vision that helps to see what is on the sides). But if a patient has a bilateral stroke of the occipital lobes, then his vision in both eyes can be greatly reduced.

In stroke in general, there may be impaired visuospatial function, visual attention, or difficulty with visual recognition.

If a person is affected by the brain stem during a stroke, then this can lead to double vision. Sometimes a stroke causes involuntary eye movements, called nystagmus.
