Summary

Visual loss after spine surgery can occur even without clear risk factors. Neurosurgeons should maintain a high suspicion for visual changes in patients post-operation.

Area of Science:

  • Neurosurgery
  • Ophthalmology
  • Patient Safety

Background:

  • Perioperative visual loss is a rare but serious complication following spine surgery.
  • Identifying predisposing risk factors is crucial for prevention and early detection.

Purpose of the Study:

  • To survey neurosurgical spine surgeons about risk factors associated with visual loss after spine surgery.
  • To gather data on the incidence and potential causes of perioperative visual disturbances.

Main Methods:

  • A survey was distributed to members of the American Association of Neurological Surgeons/Congress of Neurological Surgeons, Section on Disorders of the Spine and Peripheral Nerves.
  • The survey focused on intraoperative factors potentially leading to perioperative visual loss.

Main Results:

  • 290 surveys were returned, with 24 cases of visual loss reported by 22 surgeons.
  • Identified risk factors included hypotension and low hematocrit levels, but 8 cases lacked apparent causative factors.

Conclusions:

  • A high index of suspicion for perioperative visual loss is necessary, even when risk factors are not evident.
  • Further investigation may be warranted to understand the etiology of visual loss in patients without identifiable risk factors.
