  • *patients who were scanned more than once.

  • **Time since the initial insult causing the hemianopia occurred, in years.

  • †Mean deviation computed for each hemifield, with the unaffected hemifield in brackets.

  • ‡Location where patients were scanned (UK or Brazil). Age and lesion duration details for patients with multiple scans refer to the latest scan acquired. Patients’ identifier beginning with ‘T’ indicates optic tract damage, ‘L’ is lateral geniculate nucleus, ‘R’ is optic radiation, ‘S’ is striate cortex and ‘O’ is occipital lobe.

  • LGN, Lateral geniculate nucleus. Patients with congenital damage are indicated with ‘c’
