A hand-instrument is described, which serves the purpose of direct and indirect ophthalmoscopy. One part of the instrument, which may be used alone, is a direct ophthalmoscope; it comprises as a distinctive feature a mirror which is vertically movable. The other part is an attachment comprising magnifying lenses, a system for viewing the fundus periphery, a movable fixation target, a system for seeing the patient's eye, and a demonstration mirror. Both parts together form a light, easy-to-handle unit for monocular indirect ophthalmoscopy.
