Fundus photographing apparatus

摘要

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.

主权项

1. A fundus photographing apparatus for photographing a fundus of an examinee's eye, the apparatus comprising:
a photographing part including a photographing optical system for photographing the fundus of the eye; a moving mechanism for relatively moving the photographing part with respect to the eye; a fixation target presenting part for presenting a fixation target to the eye; a detecting part for detecting a deviation amount in up and down, right and left directions of a photographing optical axis of the photographing part with respect to a reference position of the eye; and an alignment completion position setting part for setting, while a visual line of the examinee's eye is fixed in a predetermined direction by the fixation target presenting part, an alignment completion position in a back and forth direction of the photographing part with respect to the examinee's eye based on the deviation amount in the up and down, right and left directions of the photographing optical axis detected by the detecting part so that the alignment completion position in a back and forth direction is stored as a different value in memory in association with the deviation amount in the up and down, right and left directions.
