What Is Optic Neuritis?
7. How Is Optic Neuritis Diagnosed?
An ophthalmologist generally conducts a thorough eye exam, which includes an ophthalmoscopy and a pupillary light reaction test. These allow the doctor to assess visual acuity, color discrimination and the range of your visual field, as well as eye structure and light response.
A magnetic resonance imaging scan may be ordered to determine whether there are lesions on the brain and to assess where the swelling is occurring along the optic nerve. Blood tests are also possible. These are used to determine the presence of antibodies, which can provide clues about alternative causes of optic neuritis.
