The occipital lobe spans across both hemispheres of the brain. When stroke affects the occipital lobe on one side, it can cause blindness on the opposite side of the visual field. For example, a stroke in the right occipital lobe can result in blindness on the left side of the visual field. Cortical Blindness Occipital lobe damage can cause a person to experience different vision problems. While other types of TBI may result in a wide variety of side effects, damage to the occipital lobe is unique because it generally affects one thing: sight. However, vision problems can manifest in different ways. This makes it important to gain a Occipital Lobe Damage: How It Affects Vision & Recovery.

The Occipital Lobe is one of the four major regions of the Cerebral Cortex in mammals. It is positioned in the back of the brain and houses the Visual Cortex. 10. This region of the brain receives input from the retina. These signals are essentially interpreted by the occipital lobes. Location of the Occipital Lobe 10 We present a case of a patient with Anton's syndrome (i.e., visual anosognosia with confabulations), who developed bilateral occipital lobe infarct. Bilateral occipital brain damage results in blindness, and patients start to confabulate to fill in the missing sensory input. In addition, the patient occasionally becomes agitated and talks to himself, which indicates that, besides Anton&#.
