What is split vision during a stroke?

Dr. Mehmet Oz, MD
Cardiologist (Heart Specialist)

Strokes can cause many different symptoms, including slurred speech or difficulty walking. Experiencing “split vision” in each eye—a lesser known symptom—can also occur. In this case, you have only half a field of vision in each eye. For instance, if you were looking at a stop sign, you may only see the O and the P, while the S and T remain invisible.

This occurrence may last for only several minutes until vision is restored, but it still indicates that the visual cortex in the back of the brain has been impacted by loss of blood flow. A CT scan or MRI would reveal that this part of the brain controlling your vision experienced a cutoff in its blood supply. Mini strokes may present themselves this way and are often a precursor to a major stroke.
