Summary
Traumatic globe evulsion can disrupt the optic nerve and its sheath in unique ways, sometimes leaving the nerve behind or causing defects at the lamina cribrosa.
Area of Science:
- Ophthalmology
- Trauma Surgery
- Pathology
Background:
- Traumatic globe evulsion is a severe ocular injury.
- Understanding the patterns of optic nerve and sheath disruption is crucial for managing these cases.
Observation:
- This case series details 3 patients with traumatic globe evulsion.
- Clinical, gross, and microscopic findings of the evulsed globes were analyzed.
Findings:
- Optic nerve and sheath disruptions occurred at varied locations and extents.
- Unique injury patterns included sheath evulsion without the nerve, and nerve/sheath avulsion at the lamina cribrosa.
Implications:
- These findings expand the understanding of optic nerve injury mechanisms in traumatic globe evulsion.
- Novel injury patterns highlight the complexity of orbital trauma and necessitate further investigation into causative mechanisms.
