摘要： An ocular blood-flow meter includes an optical system for applying measuring light to a blood vessel of a subject eye, and for receiving light scattered by the blood vessel of the subject eye. A mechanism is provided for changing a direction in which the measuring light is applied and a direction in which the scattered light is received so as to enable a plurality of measurements in different directions. A controller performs the plurality of measurements in the different directions by using the optical system and the mechanism so as to obtain information concerning a blood flow. An output device provides a received-light signal obtained by the optical system or the information concerning the blood flow. An input device enables an operator to select a re-measurement operation in a desired direction from the different directions and to instruct the selected re-measurement operation.
