Title:
OPHTHALMOLOGIC APPARATUS, CONTROL METHOD THEREOF, PROGRAM, AND RECORDING MEDIUM
Document Type and Number:
Japanese Patent JP2019213740
Kind Code:
A
Abstract:
To reduce a burden on a subject and an examiner by automating a preparatory operation for applying OCT to the anterior eye part of a living eye.SOLUTION: A scan area setting unit of an ophthalmologic apparatus of the example embodiment sets a scan area in a region passing through an iris periphery. A first scan control unit controls an OCT optical system so as to apply an OCT scan to this scan area. An image quality evaluation unit calculates an image quality evaluation value of an image based on the OCT scan to the scan area. An angle image detection unit analyzes the image based on the OCT scan to the scan area and detects an angle image. A position determination unit determines whether or not the angle image is positioned within a first range in an image frame. A second scan control unit controls the OCT optical system so as to apply an OCT scan of a predetermined pattern to the anterior eye part when the image quality evaluation value is a predetermined threshold or more, and the angle image is positioned within the first range.SELECTED DRAWING: Figure 8
