摘要： Fundus examination is effected by the steps of irradiating the fundus of an examined eye with a measuring beam through a deflector, irradiating the fundus of the eye with a tracking beam through the deflector to thereby obtain tracking information, and controlling the deflector on the basis of the tracking information and executing tracking, calculating a position at which the reliability of a signal obtained by a light receiving system is relatively improved during the tracking, and controlling the deflector so that the measuring beam may be irradiated to this position; and frequency-analyzing the signal obtained by the light receiving system and calculating the velocity of blood flow. The aforementioned reliability is evaluated by means of the SN ratio and quality value of the signal.

摘要： When the fundus camera is positioned on the same side as the subject's eye relative to an appropriate position (front-focus state), the positioning index light source turned on in blue produces most-focused positioning index images. The positioning index light sources become more blurred in order of green and red. When the camera is positioned on the opposite side of the subject's eye relative to the appropriate position (rear-focus state), the positioning index light source turned on in red produces most-focused images. The positioning index light sources become more blurred in order of green and blue. Based on a degree of the blur of the individual positioning index images in red, green, and blue reflected by the cornea of the subject's eye, the calculation unit calculates whether to move the camera body closer to or farther away from the subject's eye and allows the display unit to display the information.

摘要： Provided is an ophthalmologic image taking apparatus with which an image of the eye to be examined can be taken with an appropriate light intensity and at an appropriate gain. In the case where an observation of an eye to be examined is conducted when it is detected that an image taking switch is turned on, an image taking light source emits light after a lapse of a predetermined time. The predetermined time is a time required to completely switch a gain from a gain obtained by AGC to a fixed gain and a time which is not influenced by blinking of the eye to be examined.

摘要： There is provided an ophthalmologic apparatus. According to the ophthalmologic apparatus, irradiating times of tracking light and measuring light are measured for each measured part and then an energy integrated value Ex is calculated. Further, MPE is calculated based on a period from the time of irradiation to the current time and the proportion of the integrated value Ex to the MPE is calculated and displayed. When the proportion of the integrated value Ex to the MPE is 100% or more, tracking light irradiation is stopped. When the proportion of the integrated value Ex to the MPE has not reached 100%, measurement using the measuring light is conducted while the proportion of the integrated value Ex to the MPE is obtained.
