H47: Other disorders of optic [2nd] nerve and visual pathways

H47.3: Other disorders of optic disc

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 nerve starts at the back of the eye. The beginning of the optic nerve can be seen when examining the eye.

The beginning of your optic nerve has changed. Deposits may accumulate at the beginning of the optic nerve, for example, or the beginning of the optic nerve looks different in the examination.

Damage to the beginning of the optic nerve means you may not be able to see some areas in your visual field or they may be blurred.
