About Sight Loss following a Stroke
Visual problems are common after a stroke (some research suggest up to 2 out of 3 people who have a stroke experience problems with their sight) and sometimes they occur without any other disability being present.

Like other after-effects of stroke, visual problems often resolve themselves in time as the brain recovers, although where recovery doesn't happen, they can be quite difficult to adjust to. If a person is having trouble with vision, this can affect the rest of their rehabilitation - for example moving around could become more difficult. Problems with vision can sometimes be missed, so if you think you, or someone you know, has visual problems after a stroke, you should talk to your doctor.
Hemianopia is the loss of sight to one side of the field of vision. People who have a stroke to one side of their brain may develop field loss to the opposite side.
The Stroke Association have produced a Fact Sheet on sight loss following a stroke and you can download it here. Further information from the Stroke Association.
