H48.8: Other disorders of optic nerve and visual pathways in diseases classified elsewhere

To be able to see, light needs to fall into our eye. The light falls through the eye to a layer inside the eye. From there, the optic nerve routes the information on to the brain. The brain converts these impressions to images.

The optic nerves connect the eyes to the brain. The two optic nerves cross on their way through the brain to the visual center. The visual center in the brain is where the information from the eyes is processed. The nerve connection from the eyes to the visual center is called the visual pathways.

In your case, the visual pathways have changed. In your case, this change to the visual pathways is a result of another disease.

Any change to the visual pathways means you may not be able to see some areas in your visual field or they may be blurred. You may also find it difficult to see in the entire field of vision.
