Provided is a microscope apparatus including: a microscope section configured to perform magnified observation of a subject's eye while obtaining a red reflex caused by irradiating a fundus of the subject's eye with illuminating light； a holding section configured to hold the microscope section； and a tilting section configured to tilt an illumination optical axis which is an optical axis of an illumination optical system, and an observation optical axis which is an optical axis of an observation optical system in the microscope section, around a tilt reference point in an interior of the subject's eye as a base point, while maintaining a substantially coaxial state between the illumination optical axis and the observation optical axis.
