An ophthalmologic observation apparatus comprising: a measuring optical system configured to perform optical coherence tomography of an eye; an image forming part configured to form an image of the eye based on information acquired by the optical coherence tomography; and a preliminary operation performing part configured to perform a plurality of preliminary operations for optical coherence tomography, the plurality of preliminary operations comprising one or more of alignment of the measuring optical system with respect to the eye, focus adjustment of the measuring optical system with respect to the eye, adjustment of an optical path length difference between the signal light and the reference light, and polarization adjustment of the signal light and/or the reference light, characterized by: a storage configured to store in advance, for at least one specific preliminary operation among the four explicitly afore-mentioned plurality of preliminary operations, operating condition information including a transferring condition for transferring to a different preliminary operation among the four explicitly aforementioned preliminary operations and a terminating condition for terminating the specific preliminary operation; and a controller configured to control the preliminary operation performing part to commence the specific preliminary operation, control the preliminary operation performing part to commence the different preliminary operation when the transferring condition of the specific preliminary operation is satisfied, and control the preliminary operation performing part to terminate the specific preliminary operation when the terminating condition of the specific preliminary operation is satisfied, wherein the specific preliminary operation is continued, after the transferring condition of the specific preliminary operation has been satisfied, until the terminating condition of the specific preliminary operation is satisfied. a measuring optical system configured to perform optical coherence tomography of an eye;
