An apparatus for cross-sectional imaging of an anterior ocular segment (11) wherein a stationary cylindrical body (96) disposed projecting out from a body of the apparatus (11), and an illuminating optical system (12) and an imaging optical system (14) are disposed within the cylindrical body (96) with a front aperture (97) of the cylindrical body (96) as a common aperture thereof so as to be rotatable in unison about an eye-side optical axis (O le ) of the illuminating optical system (12). At least one proximal direction reflecting mirror (38, 40) being disposed within an interior of the cylindrical body (96) in proximity to the front aperture (97) for reflecting scattered light by the examined eye (E) on an optical axis (O 2 ) of the imaging optical system (14) to a direction proximate to an optical axis (O 1 ) of the illuminating optical system (12).
