Abstract

A stereoscopic ophthalmoscope for examining an eye including two inner reflection mirrors for guiding light representing the image of the eye toward a pair of external mirrors. Each of the external mirrors serves as an image splitter for dividing the light into two distinct optical observation paths. The first optical observation path is used to produce a stereoscopic image of the eye suitable for binocular viewing. The second optical observation path is used to produce a non-stereoscopic image of the eye suitable for monocular or binocular viewing.
