H48: Disorders of optic [2nd] nerve and visual pathways in diseases classified elsewhere
H48.1: Retrobulbar neuritis in diseases classified elsewhere
The retina is a layer inside the eye. It contains a lot of sensory cells that can perceive light. There are sensory cells for colors and sensory cells for light and dark. The sensory cells pass the information on to the nerve cells in the optic nerve. Your optic nerve has become inflamed as a result of another disease.
When the optic nerve is inflamed, the person’s vision usually gets worse quickly. The affected eye is sore, too. The pain may become more severe if one moves one’s eyes. And one may see colors in an abnormal way.
