A blood vessel examination apparatus includes a presentation device for presenting a fixation reference mark to the eye to be examined, an irradiation device for irradiating a blood vessel on the fundus of an eye with measurement light in accordance with the position of the fixation reference mark, and a light-receiving device for receiving light of the measurement light reflected by the fundus The apparatus also includes a computation device for computing blood vessel information of a fundus blood vessel on the basis of a light-received output of the light-receiving device, a direction detector for detecting the longitudinal direction of the blood vessel, and a controller for controlling the position of the fixation reference mark in accordance with the direction detected by the direction detector, and obtaining accurate blood vessel information (e.g., blood flow velocity) by moving the measurement light along the blood vessel.
