Abstract

<div notation="docdba" type="abstract" xml:base="/api/emi/section/d3aaa8be-58f7-4698-aa2e-8e2920056f67/image" xml:lang="en"><p>An ophthalmologic apparatus (10) comprises a measurement optical system (24) to acquire information of an eye to be examined (E), an image obtaining part (31g) to obtain an anterior ocular segment image (E') of the eye (E) on an optical axis of the measurement optical system (24), a display (30) to display the obtained anterior ocular segment image (E'), cameras (40, 41) to each capture an image of an anterior ocular segment of the eye (E) from a different direction, a driving mechanism (22) to move the measurement optical system in a vertical direction and a horizontal direction, and a controller (26). The controller (26) acquires three-dimensional position information of the eye (E) based on the images captured by the cameras (40, 41) and calculates moving amounts in the vertical and horizontal directions of the measurement optical system (24) based on the acquired position information. The controller (26) displays the anterior ocular segment image (E') on the display (30) while positioning the measurement optical system (24) with the driving mechanism (22).</p></div>
