Patent ID: 8408704

Claim:
A fundus oculi observation device, comprising: a light source configured to output a light; an interference-light generator configured to split the light into a signal light and a reference light, and superimpose the signal light propagated through a fundus oculi and the reference light propagated through a reference object to generate an interference light; a detector configured to detect the interference light and generate a detection signal; an image forming part configured to form a tomographic image of the fundus oculi based on the detection signal; a calculator configured to calculate layer thickness distribution of the fundus oculi in a cross section of the tomographic image based on the tomographic image; a specifying part configured to specify a vascular region in the tomographic image based on the tomographic image; a display; and a controller configured to control the display to display a graph having an axis defined along the cross section and an axis taking layer thickness values as layer thickness distribution information representing the layer thickness and to also display a vascular position image representing a position of the vascular region as vascular position information on the layer thickness distribution information.
