Patent ID: 7566129

Claim:
An ophthalmologic apparatus comprising: an ocular fundus photographing system that forms an image of an ocular fundus of a tested eye on a photographing apparatus based on a reflective beam from the ocular fundus; and an ocular fundus tracking controller that detects a light beam from the ocular fundus, reflected at a reflective region of an illuminated region on the ocular fundus to detect a gaze direction of the tested eye, and performs tracking with respect to the ocular fundus based on the detection result of the gaze direction, the ocular fundus tracking controller comprising: a scanning mirror for scanning an area on which a detection beam projected on the ocular fundus is detected or a reflective beam from the ocular fundus is detected; a tracking mirror for controlling tracking to the ocular fundus; an objective lens disposed opposite to the tested eye; and an offset mirror positioned between the objective lens and the tracking mirror outside of a photographing optical path for the ocular fundus, for adjusting a detection axis of the gaze direction.
