Abstract: The blood flow analysis apparatus includes an acquisition unit and an extractor. The acquisition unit is configured to acquire blood flow information representing time-course changes in a blood flow velocity of a single retinal artery or retinal vein. The extractor is configured to extract one or more parameters corresponding to change in the blood flow velocity from the blood flow information.

Abstract: A blood flow measurement apparatus of an aspect example includes a scanning optical system, a front image acquiring unit, a region-of-interest determining processor, a scan controller, and a blood flow information acquiring unit. The scanning optical system applies OCT scanning to a fundus of a subject's eye. The front image acquiring unit acquires a front image of the fundus. The region-of-interest determining processor determines a region of interest that intersects a blood vessel by analyzing the front image based on a condition set in advance. The scan controller controls the scanning optical system to apply a repetitive OCT scan to the region of interest. The blood flow information acquiring unit acquires blood flow information based on data collected by the repetitive OCT scan.
