H47: Other disorders of optic [2nd] nerve and visual pathways
H47.4: Disorders of optic chiasm
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.
Your optic nerve has changed where the optic nerves meet.
Any change to the optic nerves where they meet means you may not be able to see some areas in your visual field or they may be blurred. You may also have other symptoms such as a headache.
