PROBLEM TO BE SOLVED: To accurately obtain endogenous signals of a retina by controlling the influence of a flicker of light and obtaining a fundus image.
SOLUTION: The retinal function measurement apparatus comprises an observation/illumination optical system with a light source for observation/illumination for illuminating the retina region of an eye of a subject a light receiving optical system with a light receiving element for obtaining the fundus image by receiving the reflection light from the regina region illuminated by the observation/illumination optical system a stimulation light irradiating optical system with a stimulation light source for stimulating the retina by irradiating the retina region of the eye of the subject with the visible stimulation light from the light source and an obtaining means for obtaining the information on the variation of the fundus image by comparing the fundus images obtained by the light receiving optical system before and after the irradiation of the stimulation light. The retinal function measurement apparatus also has a detection means for receiving a part of the observation light output from the observation/illumination light source and detecting the output of the received light, and a display control means for displaying the information on the variation in the elapse of time of the observation light output from the light source based on the result of detection by the detection means.
