Abstract: A portable ophthalmic imaging device suitable for imaging an eye having a first optical axis is provided. The imaging device comprises an imaging module comprising a plurality of optical elements including a light sensor which define a second optical axis; an eye rest; and a plurality of motors. The plurality of motors are arranged to move the imaging module and/or the eye rest to align the first and second optical axes at least partially automatically using a feedback control system.

Abstract: The invention provides an imaging system (102) for imaging a fundus (104) of an eye (106), which has an optical axis (116). The imaging system (102) has a light source (108), an illumination path (118) along which light travels from the light source (108) to the eye (106), a light sensor (10) and imaging optics (44) defining an imaging axis (114), and at least one objective lens (112) aligned with the optical axis (116). At least a part of the illumination path (118) is substantially coaxial with the imaging axis (114), and the optical axis (116) is tilted with respect to the imaging axis (114).
