ABSTRACT:
An ophthalmologic apparatus has a projection system provided with a fixation object capable of being perceived by an examinee, the projection system being for projecting the fixation object upon a desired position on the fundus of an eye to be examined. The apparatus further has an observation system for observing therethrough a portion of the eye to be examined, and a reflecting system disposed between the fixation object and the eye to be examined for directing a light beam emitted from the fixation object to the observation system. In the reflecting system, the light beam emitted from the fixation object and incident on the reflecting system is substantially coincident with a light beam reflected thereby.
