Outline of Final Research Achievements

We performed high-resolution visual field (VF) testing at 0.5º intervals and found that visual field abnormalities were not detected sufficiently in the usual VF measurement at 6º intervals. It was found that the fluctuation of the measurement value could be significantly reduced if the fixation was controlled strictly. In order to improve the reliability of the clinical VF examination data and to clarify the more detailed relationship between the structure and the function, they are necessary to perform high-resolution measurement in the central visual field, and to reduce the influence of eye movement.
