H47: Other disorders of optic [2nd] nerve and visual pathways
H47.0: Disorders of optic nerve, not elsewhere classified
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.
Your optic nerve has changed. The optic nerve can be diseased or altered in various ways. The optic nerve may not be properly supplied with blood or it may be constricted, for example. The optic nerve can also become damaged by certain toxins or other diseases.
Damage to the optic nerve 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. You may also have other symptoms such as a headache.
