Japanese Patent JP7348334

B2

To achieve a reduction in a size and simplification of an ophthalmologic imaging apparatus which can carry out an examination of a visual field.SOLUTION: In an ophthalmologic imaging apparatus according to the embodiment, a scanning optical system scans an ocular fundus with light from a light source part including a visible light source and an infrared light source and receives return light at a light receiving part. An image forming part forms an image based on signals from the light receiving part. A control part carries out first control of the scanning optical system for projecting fixation light from the visible light source to the ocular fundus and second control of the scanning optical system for projecting stimulation light from the visible light source to the ocular fundus. The scanning optical system repeatedly receives the return light by the light receiving part while repeating scanning with the infrared light from the infrared light source. The image forming part forms images repeatedly based on the signals sequentially output from the light receiving part. An analysis part obtains displacement of the ocular fundus by analyzing the images sequentially formed. The control part controls lighting timing of the visible light source in the first control and/or the second control based on the displacement.SELECTED DRAWING: Figure 4
