Abstract

La présente invention concerne un procédé et un dispositif d'examen des champs visuels destinés à examiner les champs visuels de l'œil gauche, de l'œil droit, et des deux yeux d'un sujet alors que le sujet garde ses yeux sur une marque de fixation centrale, outre un examen du champ visuel précis sans avoir recours à un appareil d'examen du champ visuel compliqué et onéreux habituel, utilisant un écran à cristaux liquides. Des première et deuxième marques d'examen colorées (22, 23) ayant des couleurs mutuellement complémentaires et une troisième marque d'examen achromatique (24) sont affichées séquentiellement sous une condition prédéterminée d'au moins leurs positions d'affichage autour d'une marque de fixation centrale (21) affichée à une position prédéterminée sur un écran d'affichage (2). On vérifie si le sujet portant des filtres (81, 82) des mêmes couleurs que celles des première et deuxième marques d'examen (22, 23) sur ses yeux gauche et droit respectifs peut ou non reconnaître visuellement les marques d'examen alors qu'il regarde la marque de fixation centrale (21). La condition d'affichage des marques d'examen est comparée à l'état de reconnaissance visuelle pour ainsi indépendamment examiner les champs visuels de l'œil gauche, de l'œil droit, et des deux yeux du sujet.
