This report details a young man with unusual "ping pong gaze" (PPG) after a head injury. Oculography confirmed a saccadic type of this periodic alternating gaze, differing from previously described smooth deviations.

Area of Science:

  • Neuroscience
  • Ophthalmology
  • Neurology

Background:

  • Head injuries can cause complex neurological symptoms affecting eye movement control.
  • Periodic alternating gaze is a known phenomenon, often associated with smooth eye deviations.

Observation:

  • A young male patient presented with coma following a head injury.
  • Observed peculiar, rhythmic, side-to-side eye movements without pauses at lateral positions.

Findings:

  • The patient exhibited a saccadic type of ping pong gaze (PPG), confirmed by oculography.
  • This saccadic PPG contrasts with the previously documented smooth deviation form.

Implications:

  • The findings suggest a specific oculomotor pathway dysfunction in saccadic PPG.

  • Understanding PPG subtypes is crucial for diagnosing and managing traumatic brain injuries.
  • Further research is needed to explore the clinical and pathophysiological basis of saccadic PPG.
