Post-operative bilateral vision loss

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.
