Optic Nerve Atrophy in N-methyl-D-aspartate (NMDA) Encephalitis

Area of Science:

• Neurology
• Immunology
• Ophthalmology

Background:

• N-methyl-D-aspartate receptor (NMDA) encephalitis is an autoimmune disorder.
• It often presents with psychiatric and neurological symptoms.
• Tumors, particularly teratomas, are associated with NMDA encephalitis.

Observation:

• Optic neuropathy is an increasingly recognized complication of NMDA encephalitis.
• This report details a case of bilateral optic neuropathy in a young male patient.
• The patient was diagnosed with NMDA receptor encephalitis.

Findings:

• The diagnosis of NMDA encephalitis was confirmed by detecting NMDA antibodies.
• The patient presented with bilateral optic neuropathy.
• This case adds to the literature on visual disturbances in NMDA encephalitis.

Implications:

• Ophthalmologists and neurologists should consider NMDA encephalitis in patients with unexplained optic neuropathy.
• Early diagnosis and treatment of NMDA encephalitis may improve visual outcomes.
• Further research is needed to understand the mechanisms of optic nerve involvement in autoimmune encephalitis.
