20220386864 · 2022-12-08 · ·

An OCT apparatus processes an OCT signal based on reference light and measurement light with which a subject eye is irradiated to capture a tomographic image of a tissue of the subject eye. The OCT apparatus includes a controller. The controller captures a three-dimensional tomographic image of the tissue by irradiating a two-dimensional measurement region, which expands in a direction intersecting an optical axis of the measurement light, with the measurement light. The controller extracts a two-dimensional tomographic image from the three-dimensional tomographic image to display the two-dimensional tomographic image on a display unit. The controller sets an additional imaging position of a tomographic image in a state where the two-dimensional tomographic image is displayed on the display unit. The controller performs additional capturing of a tomographic image by irradiating the set additional imaging position with the measurement light.
