Optical apparatus for retinal photography includes a housing (20) fitted to or adapted to be fitted to a camera and defining an optical path (21) that is aligned with the camera lens assembly and extends therefrom to a nose region (25) of the housing. The housing has a projecting handle (24) dimensioned and profiled to be grasped by hand for holding the apparatus in one hand. A plurality of lens components (42, 44) in the optical path and an illumination source (46) co-operate to illuminate a retina of an eye in front of the nose region of the housing, and to image the illuminated retina at the image sensor of the camera.
