Studies on the visual evoked response: III. Strabismus amblyopia and hysterical amblyopia

  • Albert M. Potts

Article

Summary

  1. 1.

    The foveal visual evoked response is diminished or absent in strabismic amblyopia. This confirms the early report of van Balen & Henkes.

     
  2. 2.

    There is no such finding in hysterical amblyopia.

     
  3. 3.

    On the basis of the work of Hubel & Wiesel in experimental animals this confirms the idea that strabismic amblyopia corresponds to an anatomical defect and hysterical amblyopia does not.

     
  4. 4.

    Practical applications of these findings are suggested.

Résumé

  1. 1.

    La réponse corticale évoquée à partir de la fovéa est diminuée ou absente dans l'amblyopie strabique. L'observation antérieure de van Balen & Henkes est ainsi confirmée.

     
  2. 2.

    Dans l'amblyopie hystérique rien de pareil ne se produit.

     
  3. 3.

    Sur la base des travaux expérimentaux de Hubel & Wiesel on peut maintenant considérer l'amblyopie strabique comme étant due à une lésion anatornique. Ceci n'est pas le cas pour l'amblyopie hystérique.

     
  4. 4.

    On envisage l'application pratique de ces constatations.

     

Zusammenfassung

  1. 1.

    Die von der Fovea aus hervorgerufene kortikale Antwort ist in der Schielamblyopie herabgesetzt oder ganz abwesend. Die frühere Beobachtung von van Balen & Henkes ist somit bestätigt.

     
  2. 2.

    In der Hysterie-Amblyopie findet sich nichts derartiges.

     
  3. 3.

    Auf der Grundlage der experimentellen Arbeiten von Hubel & Wiesel kann jetzt die Schielamblyopie als die Folge eines anatomischen Defekts angesehen werden. Dies ist bei der Hysterie-Amblyopie nicht der Fall.

     
  4. 4.

    Die praktische Anwendung dieser Befunde ist vorgesehen.
