Abstract
An ophthalmologic apparatus is disclosed. In one aspect, the apparatus includes an 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 an ocular fundus tracking controller for detecting a gaze direction of the examined eye by receiving the reflective beam reflected at a reflective region of an illumination region illuminated on the ocular fundus and for tracking the ocular fundus based on the detection results of the gaze direction. The ocular fundus tracking controller may include scanning mirrors for scanning an area to detect a reflective beam from the ocular fundus, tracking mirrors for controlling tracking to the ocular fundus, an objective lens disposed opposite to the examined, and an offset mirror Mfor adjusting a detection axis in a gaze direction.
