Bilateral cortical blindness after lumbar spine surgery. A case report
Spine
|September 5, 1998
Summary
This case report details a rare instance of bilateral cortical blindness following lumbar spine surgery. Obese patients require careful consideration during procedures involving subclavian vein puncture and patient repositioning.
Area of Science:
- Ophthalmology
- Neurosurgery
- Anesthesiology
Background:
- Reports of perioperative cortical blindness after lumbar spine surgery are exceptionally rare.
- This study addresses an unusual case to highlight potential risks and preventive measures.
Observation:
- A patient developed bilateral cortical blindness after lumbar spine surgery.
- Visual impairment persisted, with only partial ability to distinguish light from dark and some color perception.
Findings:
- The case report explores hypothetical causes of cortical blindness in the context of spine surgery.
- Diagnostic tools and pathophysiologic mechanisms contributing to this rare complication are discussed.
Implications:
- Careful patient positioning and procedures like subclavian vein puncture require heightened vigilance in obese individuals (BMI > 30).
- Understanding risk factors and implementing precautions may help prevent this severe visual complication in spinal surgery patients.
