Summary

Blunt ocular trauma can cause rare optic disc swelling. Despite a prolonged course, this condition shows a favorable prognosis for vision recovery in young patients.

Area of Science:

  • Ophthalmology
  • Neuroscience
  • Trauma Research

Background:

  • Optic disc swelling is an uncommon complication following blunt force trauma to the eye.
  • This study investigates an unusual form of post-traumatic optic neuropathy characterized by persistent optic nerve head swelling.

Observation:

  • Three young patients presented with significant optic nerve head swelling after ocular trauma.
  • Two patients exhibited associated choroidal ruptures, indicating a contrecoup injury mechanism affecting the optic nerve near the globe.
  • The optic neuropathy presented with protracted optic disc swelling as the primary clinical sign.

Findings:

  • Patients experienced partial vision recovery over several months.
  • Vision improvement correlated with the resolution of optic disc swelling.
  • Optic disc pallor developed as the swelling subsided.

Implications:

  • Post-traumatic optic disc swelling, though prolonged, suggests a positive outlook for visual function restoration.
  • Understanding the contrecoup mechanism is crucial for diagnosing and managing such injuries.
  • This finding is important for ophthalmologists and trauma specialists managing ocular injuries.
