Abstract

An apparatus for examining the ocular fundus of an eye, in which an illuminating device is provided with non-overlapping apertures positioned substantially side by side, and in which an image of the apertures is formed on a part of the ocular fundus; an image of the illuminated ocular fundus is formed in a detecting plane in response to reflection from this fundus in such a manner as to provide a stereo pair of images of the ocular fundus in the detecting plane which are detected and then electronically processed and digitally analyzed thereby to display information about the ocular fundus under examination; the pupil position is also detected and the eye is then automatically aligned relative to the optical axis of the image, at least part of which is common to the axis of the illuminating device.
