Case Discussion

This case had an elderly patient with sudden onset visual change and an underlying infarct in the left occipital region.  The mild symptoms of dizziness and uncoordination can be part of visual disturbance but are also controlled by a similar blood supply (the brain stem and cerebellum are posterior circulation structures).  Further investigation of this patient with cardiac work up and vessel imaging may be of benefit.  Treatment for this is as for other strokes, and thrombolysis is time dependent.
