Abstract

Glaucoma is a disease that causes optic nerve damage and loss of the field of vision. It is characterized by an inability to see part of the visual field, or blurring of the visual field, as if by a mist. We therefore took static visual field measurements in individuals with unimpaired vision and those with glaucoma, both confirmed in standard visual acuity and visual field ophthalmological examinations, and then compared gaze movements during driving simulations. In this experiment, EMR-9 and EMR-8 eye mark recorders (NAC Image Technology Inc.) were used for eye tracking. All gaze points during driving were measured, and the ellipse containing 95% of the measured points was drawn. Among participants with glaucoma, the area of the ellipse containing 95% of gaze points was relatively small, indicating that they could only see a narrow range. While this range also widened on the course with colliding vehicles for the glaucoma participants, the increase was not as large as that for unimpaired participants.
