Abstract
Official abstract text for this publication.
A fundus photographing apparatus for photographing a fundus of an examinee's eye includes: a photographing part including a photographing optical system for photographing the fundus; a mechanism for moving the photographing part; a presenting part for presenting a fixation target to the eye; an alignment detecting optical system including a light receiving element to detect an alignment state of the photographing part; and a setting part for setting an alignment completion position in a back and forth direction of the photographing part relative to the eye based on the detected alignment state. The alignment completion position includes a first alignment completion position information to be set when an optical axis of the photographing part is in a predetermined range relative to a corneal vertex of the eye and a second alignment completion position information to be set when the optical axis is apart from the predetermined range.
