Summary

Anterior ischemic optic neuropathy (AION) after neck dissection is rare. Prolonged postoperative bleeding, even if mild, may be a risk factor for developing AION, requiring careful patient monitoring.

Area of Science:

  • Ophthalmology
  • Neurosurgery

Background:

  • Anterior ischemic optic neuropathy (AION) is a rare complication following head and neck surgery.
  • Published cases of AION post-neck dissection are limited, with only two previously reported.

Observation:

  • This report details a unique case of bilateral AION occurring after neck dissection.
  • The patient presented with AION despite the absence of typical risk factors like hypotension or massive hemorrhage.
  • Symptoms manifested later than in previously reported cases, appearing after the fifth postoperative day.

Findings:

  • Prolonged, diffuse postoperative bleeding was identified as a potential risk factor for AION in this case.
  • The delayed onset of symptoms differentiates this case from prior literature.

Implications:

  • Mild, prolonged postoperative bleeding should be considered a risk factor for AION after neck dissection.
  • Visual loss in the first postoperative week necessitates exclusion of AION and other complications, distinct from patient confusion or withdrawal symptoms.
