Optic Nerve Decompression Consent Checklist

A comprehensive informed consent for optic nerve decompression surgery must include detailed information about the procedure, risks, benefits, alternatives, and expected outcomes with emphasis on visual function and quality of life.

Procedure Information

  • Description of optic nerve decompression as a surgical procedure to relieve pressure on the optic nerve
  • Explanation of the endoscopic approach through the nasal cavity (if applicable)
  • Clarification that the procedure involves removing bone around the optic canal to decompress the nerve
  • Expected duration of surgery and type of anesthesia to be used

Timing Considerations

  • Clear explanation that timing of surgery is critical for outcomes:
    • Surgery within 72 hours of trauma offers best chance for complete visual recovery 1
    • Surgery between 3-7 days offers possibility of partial improvement 1
    • Surgery after 7 days has significantly reduced chance of visual improvement 1

Potential Benefits

  • Possible improvement in vision (occurs in approximately 55% of cases) 2
  • Prevention of further visual deterioration
  • Potential for better outcomes in patients with gradual vision loss compared to immediate blindness 2

Risks and Complications

  • Common side effects:

    • Nasal congestion and discharge
    • Temporary sinus pressure or pain
    • Temporary numbness around the surgical site

  • Serious potential complications:

    • No improvement or worsening of vision
    • Cerebrospinal fluid leak
    • Infection (sinusitis, meningitis)
    • Damage to surrounding structures (carotid artery, orbital contents)
    • Hemorrhage
    • Anesthesia-related complications (including sore throat, damage to teeth/lips, cognitive dysfunction) 3

Alternative Treatment Options

  • Medical management with high-dose steroids
  • Observation without intervention
  • Combined approach (steroids plus surgery)
  • Explanation that no standardized treatment protocol exists for traumatic optic neuropathy 1

Expected Outcomes

  • Realistic discussion of prognosis based on:

    • Timing of intervention
    • Mechanism of injury (direct vs. indirect)
    • Preoperative visual status
    • Presence of optic canal fractures

  • Clear statement that complete visual recovery is not guaranteed

  • Explanation that the procedure is minimally invasive with generally good tolerability 4

Postoperative Care

  • Expected hospital stay and recovery time
  • Activity restrictions after surgery
  • Follow-up schedule for visual assessment
  • Signs and symptoms requiring immediate medical attention

Documentation Requirements

  • Written documentation of the consent discussion in the medical record 3
  • Verification that the patient had opportunity to ask questions and have them answered 3
  • Documentation that the patient understood the nature of treatment and specific risks/benefits 3
  • Use of professional interpreters when needed (not family members) 3

Special Considerations

  • Provision of information in appropriate format (including Braille or large print for patients with visual impairment) 3
  • Allowing sufficient time for the patient to consider options before making a decision 3
  • Ensuring consent is obtained well before the procedure, not immediately before surgery 3

The consent process should be tailored to the individual patient's needs and circumstances, with particular attention to their specific visual condition, mechanism of injury, and time elapsed since injury, as these factors significantly impact potential outcomes.
