H48: Disorders of optic [2nd] nerve and visual pathways in diseases classified elsewhere
H48.0: Optic atrophy 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.
Your optic nerve has receded as a result of another disease and has become narrower as a result. These could be circulatory disorders, injuries or inflammation. Alcohol, tobacco or certain medicines can also lead to the optic nerve becoming narrower.
When the optic nerve becomes smaller, 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.
