H46: Optic neuritis
Your optic nerve is inflamed.
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. The optic nerve can become inflamed due to other disorders or to pathogens, for example.
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.
