Optic Neuropathy Symptoms
Your optic nerve helps your brain to receive and interpret visual images. Each eye has an optic nerve which travels to the brain. At one point both optic nerves join together. They then split into four nerves. Each original optic nerve splits into two and one half crosses over to the other side. Due to this complex pathway, when there is damage to this nerve, there are changes to your vision based on where in the nerve's path the damage occurs. Vision changes can occur in one or both eyes.
