Abstract
An illumination system of an ophthalmologic apparatus of an exemplary embodiment projects illumination light from a light source onto the anterior eye segment of a subject's eye. An interference photographing system photographs an interference pattern formed on the cornea by the illumination light. An anterior eye segment photographing system photographs the anterior eye segment onto which the illumination light is being projected. A first optical path coupling element couples the optical path of the interference photographing system and the optical path of the anterior eye segment photographing system with one another. A controller controls a display device to display an observation interference image that is at least part of an interference image acquired by the interference photographing system and an anterior eye segment image acquired by the anterior eye segment photographing system together with each other, and controls the display device to display observation location information indicating a location of the observation interference image in the anterior eye segment image.
