An optical image measurement device has: an interference-light generator (150) configured to generate an interference light (LC) by splitting a low-coherence light into a signal light (LS) and a reference light (LR) and superimposing the signal light having passed through an eye (E) and the reference light having passed through a reference object (174) a detector (184) configured to detect the generated interference light and a scanner (141) configured to scan a projection position of the signal light on the eye, and the optical image measurement device is configured to form an image of the eye based on a result of detection by the detector. The optical image measurement device comprises a projector (140) configured to project fixation information for fixing the eye onto a fundus oculi (EF) of the eye when the scanner scans with the signal light.
