Abstract

According to an ophthalmological apparatus of an embodiment example, a light beam projecting system includes an optical scanner and projects a light beam onto an eye fundus. A fixation system projects fixation light onto the eye fundus. A photographing device captures a moving image of the eye fundus onto which the fixation light is being projected, to acquire a front observation image. An analyzing circuitry analyzes the front observation image to specify the position of a predetermined site of the eye fundus. A controlling circuitry controls at least one of the fixation system and the optical scanner based on the positional relationship between the position of the predetermined site specified by the analyzing circuitry and a projection target area of the light beam from the light beam projecting system.
