In the present invention, light from an irradiating system is made to enter the eye being examined from a direction as perpendicular to the eye as is possible. The opthalmologic microscope system according to one embodiment comprises an illuminating system, a left light-receiving system, a right light-receiving system, an irradiating system, an optical scanner, and a deflecting member. The illuminating system irradiates the eye being examined with illuminating light. The left light-receiving system draws returning illuminating light irradiated onto the eye being examined, via a left objective lens, to a left imaging element. The right light-receiving system is positioned in such a manner that the objective optical axis thereof is not parallel with the objective optical axis of the left light-receiving system, and draws returning illuminating light irradiated onto the eye being examined, via a right objective lens, to a right imaging element. The irradiating system irradiates the eye being examined with light distinct from the illuminating light, via an irradiating system objective lens. The optical scanner is used to scan the eye being examined with light from the irradiating system. The deflecting member is positioned in the proximity of the objective optical axis of each of the left light-receiving system and the right light-receiving system, and on the optical path of the irradiating system between the optical scanner and the irradiating system objective lens, and deflects the optical path.Selon la présente invention, la lumière provenant d'un système d'exposition est amenée à entrer dans l'œil examiné depuis une direction la plus perpendiculaire à l'œil possible. Le système de microscope ophtalmologique, selon un mode de réalisation, comprend un système d'éclairage, un système de réception de lumière gauche, un système de réception de lumière droit, un système d'exposition, un dispositif de balayage optique, et un élément de déviation. Le système d'éclairage exp
