Abstract

Procédé d'administration d'un test de la vision des couleurs à contraste des cônes consistant à afficher une première couleur à un premier niveau de contraste dans une première région d'un écran et une seconde couleur à un premier niveau de contraste dans une deuxième région de l'écran, à recevoir un premier signal d'entrée par l'intermédiaire d'un dispositif d'entrée qui indique si le patient reconnaît la première région, à afficher la première couleur à un second niveau de contraste dans une troisième région de l'écran et la seconde couleur à un second niveau de contraste dans une quatrième région de l'écran, à recevoir un second signal d'entrée indiquant si le patient reconnaît la troisième région, à attribuer un score lié à la sensibilité des cônes à la première couleur au niveau des premier et second niveaux de contraste, à stocker le score, et à comparer le score à un score antérieur pour calculer une progression d'une perte de sensibilité des cônes.
