Answer

Although transient vision loss in children is most often benign, a serious underlying cause should be excluded. If symptoms are medically unexplained, clinical judgment should be used in deciding on appropriate circumstances for neuroimaging studies and further investigations.

Neuroimaging studies should be considered in the following:

  • History of recent head trauma
  • Focal neurological deficits
  • Papilledema
  • Proptosis
  • Limited eye movement
  • Patients at risk of TIA or stroke (eg, diffusion-weighted imaging [MRI])

There should be a low threshold for neuroimaging studies in young children or where there are any suspicious features.
