A visual acuity examination is performed on a patient by bringing a confocal imaging apparatus up to a patient's eye. Stimuli at various points in the patient's field of view are generated while the patient fixates on a point. The patient's responses to the stimuli are recorded with the movement of the eye with is tracked with the aid of the confocal imaging apparatus. The position of said stimuli on the retina is corrected to take into account any movement of the eye between stimuli.

L'acuité visuelle d'un patient est examinée en approchant un appareil d'imagerie confocale d'un il du patient. Des stimuli sont appliqués en différents points du champ de vision du patient tandis que ce dernier fixe un point. Les réponses du patient aux stimuli sont enregistrées avec le mouvement de l'il qui est suivi au moyen de l'appareil d'imagerie confocale. La position de ces stimuli sur la rétine est corrigée pour tenir compte d'un éventuel mouvement de l'il entre les stimuli.
