Retrobulbar Neuritis

Retrobulbar neuritis is optic-nerve inflammation posterior to the globe, so the optic disc appears normal on fundus exam despite acute visual loss. It is a form of optic neuritis, often MS-associated. Clinical: acute painful monocular vision loss with eye-movement pain, afferent pupillary defect, and normal disc. Treatment: MRI for MS risk; IV methylprednisolone to speed recovery; MS-modifying therapy if indicated.

Common Symptoms

Acute painful monocular vision loss; eye-movement pain; afferent pupillary defect; normal optic disc

Causes and Pathogenesis

Demyelination behind the optic globe causes visual loss with a normal-appearing disc.

Treatment

MRI/MS workup; IV methylprednisolone; MS-modifying therapy if indicated

Preventive Measures

MS risk stratification; treat relapse.
