    摘要： A perimeter 2 capable of acquiring, as a threshold SV, a value corresponding to a response result of a subject 22 to an optotype presented with various brightness, for measurement points set across an entire measurement field of view of the ocular fundus, displaying the threshold SV as a threshold inspection result SHR and storing the same in a memory 13, comprises: a portion 15 for obtaining a pattern deviation PDV of the threshold SV relating to each measurement point RG, from the threshold inspection result SHR; a portion for 15 for obtaining a P value representing the obtained pattern deviation PDV for each measurement point RG as a probability variable, and generating a probability map image MAP4 indicating the measurement points RG separately for each P value; a portion 16 for selecting, from an abnormal measurement point group RG of points in the probability map image MAP4 in which at least a prescribed number of measurement points having a P value at most equal to 5% are continuous, and, of those, for which at least a prescribed number of points have a P value at most equal to 1%, measurement points to be used as subsequent measurement points, until ten points have been reached; and a memory 13 for storing the selected subsequent measurement points, wherein the selection of the subsequent measurement points is controlled in such a way that the measurement points RG are selected from the abnormal measurement point group in order of those having a good pattern deviation PDV.

    摘要： An image display apparatus includes: a light source part generating a plurality of light rays corresponding to respective pixels in an image that changes over time; a projecting part defining an optical path from the light source part to an eye, and forming the image on a retina of the eye by projecting the generated light rays directly on the retina through the optical path; a splitting part splitting a plurality of reflection light rays from positions in a certain site of the eye on the optical path, the positions corresponding to the respective pixels; a detecting part detecting intensities of the reflection light rays that have been split; and a processing part obtaining parameters indicative of conditions of the site at the positions corresponding to the respective pixels, based on intensities of the generated light rays and the intensities of the reflection light rays, for the respective pixels.
