Post-traumatic transient cortical blindness is a temporary vision loss after minor head injury, resolving quickly without lasting effects. Symptoms include headache and nausea, with potential links to migraine pathophysiology.

Area of Science:

  • Neurology
  • Ophthalmology

Background:

  • Post-traumatic transient cortical blindness is a rare syndrome following minor head trauma.
  • Characterized by temporary vision loss with normal neurological and funduscopic findings.

Observation:

  • Five patients (children, adolescent, young adult) presented with this syndrome in an emergency setting.
  • Symptoms included transient visual loss, headache, confusion, irritability, anxiety, nausea, and vomiting.

Findings:

  • Vision returned to normal within minutes to hours post-injury.
  • No neurological sequelae were observed in any patient.
  • The exact mechanism is unknown, but abnormal vascular response leading to transient hypoxia is hypothesized.

Implications:
