An ophthalmologic apparatus includes a first casing which includes a light source for emitting illumination light including at least one of ultraviolet light and far-infrared light so as to illuminate a fundus of an eye to be examined, and an attenuation unit attenuating at least one of the ultraviolet light and the far-infrared light included in the illumination light, and a second casing which includes at least a part of an illumination optical system for guiding the illumination light attenuated by the attenuation unit to the fundus or a part of an imaging optical system for guiding the light reflected from the fundus to an imaging unit for imaging the fundus, and which is formed of a material lighter than the material forming the first casing.
