The key areas of the visual brain are explained in our Lessons Level 1
Visual disorders linked to specific brain locations, as identified by MRI imaging.
Not everyone with the visual impairments listed below will have identifiable damage to the region in the brain.
Some people with damage in these regions will not have the visual impairments detailed.
This is just a guide, as we think, if there is known damage in certain parts of the brain, it is worth checking to see if there is evidence of the possible related visual difficulties.
On this page we are listing only the brain related impairments of vision, which you will find listed on the CVIs page, with a brief explanation and many links to learn more.
The visual disorders are often accompanied by other difficulties, for example affecting the strength on one side of the body, how sound is processed, ability to concentrate and language.
Brain Images
Diagram showing two views of the occipital, parietal and temporal lobes. The top row is looking from behind, called a posterior view. The bottom row is looking at the right side of the brain, called a lateral view.
To help explain, we have included images of the brain showing possible affected areas.
Left occipital lobe. Posterior view of the brain, with the occipital lobes coloured dark red, and the left occipital lobe marked with a white ring.
Right occipital lobe. Posterior view of the brain, with the occipital lobes coloured dark red, and the right occipital lobe marked with a white ring.
Both Occipital Lobes. Posterior view of the brain, with the occipital lobes coloured dark red.
Left posterior parietal lobe. Posterior view of the brain, with the parietal lobes coloured dark red, and the posterior (back of) the left parietal lobe marked with a white circle.
Right posterior parietal lobe. Posterior view of the brain, with the parietal lobes coloured dark red, and the posterior (back of) the right parietal lobe marked with a white circle.
Severe damage on both sides to either cortex (outer layer of grey matter) and / or white matter. Grey and white matter explained in Lesson 1a.
Both posterior parietal lobes. Posterior view of the brain, with the parietal lobes coloured dark red, and the posterior (back of) the both the parietal lobe marked with a white circle.
White Matter Damage
Parietal lobes. Posterior view of the brain, with the parietal lobes coloured dark red.
Left temporal lobe. Posterior view of the brain, with the temporal lobes coloured dark red, and the left temporal lobe marked with a white ring.
Right temporal lobe. Posterior view of the brain, with the temporal lobes coloured dark red, and the right temporal lobe marked with a white ring.
Temporal lobes. Posterior view of the brain, with the temporal lobes coloured dark red.

At CVI Scotland we are devoted to helping people understand cerebral visual impairments, and together working towards developing the understanding of this complex condition.
