  • The Eye

A contraction of the visual field to such an extent that only a small area of central visual acuity remains.

  • Symptômes (Médecine)
  • Oeil

Lorsque la vision périphérique (le pourtour du champ visuel) disparaît suite à une destruction des cellules rétiniennes appelées bâtonnets, le champ visuel se restreint et la vision se limite peu à peu à la vision centrale, comme si l'on regardait à travers un tube, d'où le nom de vision tubulaire.
