Abstract
An ophthalmologic apparatus of some exemplary embodiments includes an illumination system, interference photographing system, anterior eye segment photographing system, first optical path coupling element, and controller. The illumination system projects illumination light output from a light source, onto the anterior eye segment of a subject's eye. The interference photographing system performs photographing of an interference pattern formed on the cornea by the illumination light. The anterior eye segment photographing system performs photographing of the anterior eye segment onto which the illumination light is being projected. The 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. The controller controls a display device to display an interference image acquired by the interference photographing system, over an anterior eye segment image acquired by the anterior eye segment photographing system.
