Stokes can cause vision problems including visual field loss, double or blurry vision and can also affect visual processing.

What test shows if you had a stroke?

A CT scan of the head is usually one of the first tests used for a stroke. A CT scan can show bleeding in the brain or damage to brain cells. The CT scan also can find other problems that can cause stroke symptoms. Magnetic resonance imaging (MRI).
