Abstract

An ophthalmologic apparatus is disclosed. In one aspect, the apparatus includes ocular fundus photographing systems for forming an ocular fundus image of the examined eye, based on a reflective beam from the ocular fundus of the examined eye, and a light receiving element for receiving the reflective beam reflected at a reflective region of an illumination region illuminated on the ocular fundus. The apparatus further may include a tracking detector having a scanning unit for detecting a gaze direction of the tested eye, and an ocular fundus tracking controller for tracking the ocular fundus photographing system to the gaze direction.
