A purpose of an embodiment is to quantitatively evaluate degrees of errors in follow up OCT imaging. An ophthalmologic imaging apparatus is capable of carrying out follow up imaging for acquiring a cross sectional image by referring to a front image of an eye acquired in the past and scanning the same position as before with light, and includes: a photographing part configured to photograph the eye and acquire a front image thereof； a cross sectional image forming part configured to scan the eye with light and form a cross sectional image thereof； a storage configured to store a first front image of the eye and a second front image acquired in follow up imaging carried out with referring to the first front image； an information obtaining part configured to analyze the first and second front images and obtain misregistration information between these front images； and a calculator configured to calculate an evaluation value of an error in a scanning position in the follow up imaging based on the misregistration information.
