Summary

Surgical decompression of the orbit and optic nerve via a lateral facial approach can restore some vision in cases of traumatic blindness unresponsive to other treatments. This procedure offers a potential solution for severe orbital trauma impacting vision.

Area of Science:

  • Ophthalmology
  • Neurosurgery
  • Trauma Surgery

Background:

  • Lateral orbital wall fractures can lead to severe visual impairment, including blindness.
  • Management of post-traumatic visual loss, particularly optic nerve compression, remains challenging.
  • Traditional treatments like lateral canthotomy and corticosteroids may not always be effective.

Observation:

  • Two cases of visual loss following lateral orbital wall fracture are presented.
  • Case 1: Retrobulbar hematoma with optic nerve compression, unresponsive to medical management.
  • Case 2: Immediate blindness due to bony optic canal fracture.

Findings:

  • Extradural decompression of the orbit and optic nerve was performed using a lateral facial approach in both patients.

Related Experiment Videos

  • Both patients experienced a partial return of visual acuity post-surgery.
  • No surgical complications were reported.

    • Implications:

    • Orbital and optic nerve decompression may be a valuable intervention for post-traumatic visual loss unresponsive to medical management.
    • Surgical decompression is a logical, though unproven, procedure when optic nerve injury is suspected.
    • Indications for optic nerve decompression require further study and should be individualized.
