Sudden vision loss after surgery can be caused by hypotension during anesthesia, leading to bilateral posterior ischemic optic neuropathies. Recovery varied between the patient's eyes.

Area of Science:

  • Ophthalmology
  • Neurology
  • Anesthesiology

Background:

  • Posterior ischemic optic neuropathy (PION) is a recognized complication following certain surgical procedures.
  • Hypotension during general anesthesia is a potential risk factor for developing PION.
  • The case highlights the importance of vigilant hemodynamic monitoring during elective surgery.

Observation:

  • A 41-year-old male experienced acute, bilateral vision loss upon waking post-elective surgery.
  • The patient's vision loss was diagnosed as bilateral posterior ischemic optic neuropathies.
  • The condition was attributed to intraoperative hypotension sustained during general anesthesia.

Findings:

  • One affected eye demonstrated notable visual improvement within a 4-week period.

  • The contralateral eye did not exhibit any significant visual recovery during the same timeframe.
  • This differential recovery suggests varying degrees of ischemic damage or individual resilience.

    • Implications:

    • This case underscores the critical link between anesthetic-induced hypotension and vision-threatening neurological complications.
    • Ophthalmologists and anesthesiologists should be aware of PION as a potential postoperative visual deficit.
    • Further research into preventative strategies and management of PION is warranted to improve patient outcomes.
