Abstract
An ophthalmologic measuring apparatus has a first projector for applying a first laser beam to a predetermined area of the fundus of an eye to be examined, a first detector for two-dimensionally detecting the reflected light of the first laser beam from the predetermined area, a first measuring device for measuring the blood flow condition in the predetermined area of the fundus of the eye on the basis of a signal obtained by the first detector for detecting the reflected light from the vicinity of a blood vessel in the spot area, a second measuring device for measuring the blood flow velocity in the blood vessel in the spot area on the basis of a signal obtained by the second detector and a calculator for adding the velocity information of each region to the blood flow condition in the predetermined area measured by the first measuring device, on the basis of the result of a measurement by the second measuring device.
