What Is Optic Neuritis?
10. What Is the Prognosis?
Many people who have one episode of optic neuritis recover full or nearly normal vision. Progress is slow and can take up to six months. After that time, any further improvement is minimal. If visual impairment is still present, it is likely to be permanent.
It is possible for people to have more than one episode, especially in those with underlying conditions such as MS or neuromyelitis optica. When there are no underlying conditions, the chances for subsequent recovery are good.
