Summary

Acute bilateral visual loss in nine patients was studied. Steroid therapy effectively treated some cases, suggesting infection-related optic neuropathy, while others showed signs of ischemia.

Area of Science:

  • Ophthalmology
  • Neurology

Background:

  • Acute bilateral visual loss is a rare condition.
  • Optic disc edema is a key clinical sign.

Observation:

  • Nine patients presented with rapid onset bilateral visual loss and optic disc edema.
  • Normal CT scans and cerebrospinal fluid (CSF) pressure were noted in most patients.
  • Two distinct patient groups emerged based on age and response to treatment.

Findings:

  • Four younger patients (22-53 years) with suspected parainfectious optic neuropathy achieved complete recovery with oral prednisolone.
  • Four older patients (55-63 years) with attenuated retinal arteries showed no significant visual improvement with steroids, suggesting an ischemic component.
  • Toxic optic neuropathy was ruled out in all cases.

Implications:

  • This study differentiates between infectious/parainfectious and ischemic causes of acute bilateral optic neuropathy.
  • Early steroid treatment may be beneficial for infection-associated optic neuropathy.
  • Ischemic optic neuropathy requires alternative management strategies.
