Richard Liebreich of Germany invented his design of ophthalmoscope in 1855. This example is complete in its case with Coccius lenses and condensing lenses. Early ophthalmoscopes required an external source of illumination, eg lamp or candle, and light was reflected into the eye to be examined by the mirror on the ophthalmoscope. A condensing lens was held in front of the patient to view the image. A Coccius lens could be clipped in to the holder to counter ametropia of user or subject.
This Liebreich ophthalmoscope is significant for the collection as it is the only complete example of the three held in the collection.
