Abstract
Official abstract text for this publication.
A corneal endothelial cell photographing apparatus includes: a main unit that includes an illumination optical system, an imaging optical system, and a fixation optical system; a setting unit configured to preliminarily set illumination positions and an illumination order of the plurality of fixation lamps; a controller configured to obtain an endothelial image at a first fixation position, control the fixation optical system corresponding to a determination result for propriety of the endothelial image obtained at the first fixation position to light a fixation lamp corresponding to a second fixation position preliminarily set by the setting unit, and control the illumination optical system and the imaging optical system to obtain an endothelial image at the second fixation position; a monitor configured to display the endothelial image; and an operating unit configured to input a signal for operating at least the controller.
First claim
Opening claim text (preview).
What is claimed is: 1. A corneal endothelial cell photographing apparatus, comprising: a main unit comprising an illumination optical system comprising an illumination light source, the illumination optical system irradiating a cornea of an examinee's eye with a light from the illumination light source, an imaging optical system comprising an imaging device to receive a reflected light from the cornea, the imaging optical system taking an endothelial image of the cornea, and…
