摘要:
A stimulus is presented at a predetermined position of a visual field coordinate system set on a visual field dome (118). When measuring the visual field of an eye under examination, quantitative information of a three-dimensional retinal layer structure is acquired that is obtained by means for detecting a range of disappearance of a peak in the reflectance distribution of the retina obtained by a retinal OCT scan. The position of the fovea of the fundus is identified from the three-dimensional retinal layer structure. From the positional relationship with the identified fovea, it is identified to which position in a two-dimensional fundus image the range of disappearance of the peak corresponds. The position corresponding to the range where the peak disappears is marked on the two-dimensional fundus image, and the marked region is detected. A visual field examination region including visual field examination points to be presented on the visual field dome is generated on the basis of the position of the marked region. The visual field examination points in the visual field examination region are presented to the subject using the visual field dome to perform a visual field examination for the eye under examination.
