A bee sting caused optic neuritis, leading to vision loss. Electrophysiology revealed optic nerve demyelination and retinal cell degeneration, with no vision recovery.

Area of Science:

  • Ophthalmology
  • Neuroscience
  • Electrophysiology

Background:

  • Optic neuritis can cause vision loss.
  • Bee stings can rarely affect the eye.
  • Electrophysiology aids in diagnosing optic nerve damage.

Observation:

  • A patient experienced severe vision loss after a bee sting on the eye.
  • Initial electrophysiological tests showed delayed pattern visual evoked potential (P100 wave).
  • Follow-up revealed absent pattern visual evoked potential and altered pattern electroretinogram (normal P50, flattened N95).

Findings:

  • The findings suggest acute optic nerve demyelination.
  • Subsequent axonal loss and retinal ganglion cell degeneration were indicated.
  • The pattern electroretinogram showed preserved retinal function initially, while the visual evoked potential indicated severe optic nerve dysfunction.

Implications:

  • This case highlights a rare cause of optic neuritis.
  • Electrophysiological recordings are crucial for understanding the pathophysiology of optic nerve damage.
  • The study suggests a progression from demyelination to axonal loss in this specific case.
