ABSTRACT:
A scanning ophthalmoscope comprises eye illuminating means comprising a light source block (A), an outward refraction compensator (Ba), scanning means (C) suitable for deflecting a beam produced by the light source block over a raster of lines, and a catoptric ophthalmoscope per se (D) for transmitting the deflected light beam into the eye through the pupil thereof. Light returns along the same path to a partially reflective beam separator plate (L.sub.1), it then passes through a return refraction compensator (Br) followed by a detector (E) and an electronic processing circuit (F). The outward and return paths are kept highly symmetrical. The catoptric ophthalmoscope (D) is essentially constituted by a spherical mirror (M.sub.1). The scanning mirrors (M.sub.3 and M.sub.4) pivot about respective axes which are colinear with the focal axes of the astigmatism which the spherical mirror produces in the image of the spot of a patient's pupil.
