Optic Neuritis Imaging

Author: Pil (Peter) S Kang, MD; Chief Editor: James G Smirniotopoulos, MD   more...

The diagnosis of optic neuritis (inflammation of the optic nerve) is usually made clinically, with direct imaging of the optic nerves by magnetic resonance imaging (MRI) being reserved for atypical cases. Optic neuritis, which is one of the causes of acute loss of vision associated with pain, can be the initial episode for a patient who will subsequently develop multiple sclerosis (MS).

Axial, short tau inversion recovery (STIR) image demonstrates faint increased signal in the distal left optic nerve.A 35-year-old woman with acute onset of left-eye pA 35-year-old woman with acute onset of left-eye pain and vision decline. Axial, fat-suppressed, postcontrast, T1-weighted image demonstrates enhancement in the intracanalicular portion of the left optic nerve.

MRI of the brain provides information that can change the management of optic neuritis and yields prognostic information regarding the patient's future risk for the development of multiple sclerosis. As established by the Optic Neuritis Treatment Trial, an abnormal baseline brain MRI scan is a strong predictor of MS after isolated optic neuritis in adults.[1, 2, 3, 4]

Preferred examination

The diagnosis of optic neuritis is usually made on clinical grounds, supplemented by ophthalmologic examination findings. However, in atypical cases (eg, prolonged or severe pain, lack of visual recovery, atypical visual-field loss, evidence of orbital inflammation and/or inflammation), MRI is used to further characterize and to exclude other disease processes.[5]
