Summary

A rare complication of prolonged surgery, posterior ischemic optic neuropathy (PION) caused complete blindness in a spinal trauma patient. This severe visual impairment resulted from circulatory stress during emergency neurosurgery.

Area of Science:

  • Ophthalmology
  • Neurosurgery
  • Trauma Care

Background:

  • Spinal column trauma necessitates complex, often prolonged, emergency neurosurgical interventions.
  • Patient positioning during surgery, such as the prone position, can impact physiological parameters.
  • Circulatory stress during extended surgical procedures is a known risk factor for various complications.

Observation:

  • A 72-year-old male with severe spinal trauma underwent prolonged emergency neurosurgery in the prone position.
  • Following the procedure, the patient developed persistent, bilateral, and complete blindness.
  • The visual loss was diagnosed as bilateral posterior ischemic optic neuropathy (PION).

Findings:

  • Posterior ischemic optic neuropathy (PION) is a rare but severe complication associated with prolonged non-ocular surgeries.
  • The condition is linked to significant circulatory stress during the surgical period.
  • The visual impairment, often bilateral, can be irreversible, leading to complete blindness.

Implications:

  • This case highlights the critical risk of PION in patients undergoing lengthy neurosurgical procedures, particularly in the prone position.
  • Awareness of PION is crucial for surgical teams to implement potential preventative strategies.
  • The permanent visual impairment resulting from PION can profoundly impact a patient's quality of life and functional independence.
