Abstract
A binocular indirect ophthalmoscope is disclosed in which the optical observation axes from the examiner's pupils to the patient's pupil and the optical illumination axis from an illumination source to the patient's pupil are varied simultaneously by a single conveniently located lever. Mirrors reflecting the observation axes and the illumination axis are mounted on a common movable holder in fixed relationship to each other. The lever is coupled to the holder to move the holder in the observation plane upon actuation of the lever and thereby adjust both the observation axes and the illumination axis at the same time.
