Abstract

An ophthalmoscope comprising (1): means (3) arranged to direct light along a path (B) exiting the ophthalmoscope (1) through a first aperture (4) and into a subject eye; a second aperture (5) through which an user can view a subject eye along a sight path (D) extending generally parallel to the exiting light path (B) ; and means (3) partially eclipsing (20) the sight path along which an user can view a subject eye. A baffle (8) may be provided between a light source and the light directing means (3) and/or the first, aperture (4) , to enhance definition of the image of the subject eye.
