とを特徴とする視野測定装置。[Claims for Utility Model Registration] A fixation target is provided on the inner surface of a substantially hemispherical dome at the pole position, and a plurality of fixation targets are provided so as to draw concentric circles corresponding to latitude lines with the fixation target as the center. In a visual field measurement device in which optotypes are arranged, each optotype is turned on to obtain measurement data in the latitude direction for each optotype, and the measurement results are output as a graph. Measurement data obtained by lighting up each of the visual targets on one side divided into two by a horizontal meridian that passes through the fixation visual target, and each visual target on the other side are located at symmetrical positions with the horizontal meridian as the boundary. A visual field measuring device characterized in that measurement data obtained by lighting up each optotype on the other side is displayed so as to correspond to each other and can be compared.
