Corneal endothelial cell photographing apparatus

A corneal endothelial cell photographing apparatus comprising:

• a main unit including:
• an illumination optical system for illuminating illumination light from an illumination light source toward a cornea of an examinee's eye from an oblique direction;
• an imaging optical system for obtaining a corneal endothelial cell image by receiving, through an imaging element, reflection light from the cornea including corneal endothelial cells;
• and
• a fixation optical system including a plurality of fixation targets and for guiding a fixation direction of the examinee's eye;
• a drive unit operable to relatively move the main unit with respect to the examinee's eye in a three-dimensional rectangular coordinate system having a first axis in a back-and-forth direction toward and away from the examinee's eye, a second axis in an up-and-down direction relative to the examinee's eye, and a third axis in a right-and-left direction relative to the examinee's eye;
• a controller configured to operate the main unit in correlation with the drive unit and the fixation optical system to obtain endothelial photographic images in series at a plurality of photographing points of a preset photographing pattern on the cornea by way of relative movement between the main unit and the cornea in at least one of the up-and-down direction and the right-and-left direction, wherein the photographing points of the preset photographing pattern are different on the cornea from one another in at least one of the up-and-down direction and the right-and-left direction;
• and
• a display control unit for causing a monitor to display the obtained endothelial image.
