Miniature Liebreich Ophthalmoscope 1875
The miniature Liebreich ophthalmoscope is a compact and historically extraordinary instrument from the 1870s. It measures just 3 inches long and comes in a fitted case measuring 2 inches by 3⅜ inches. The case lid bears the inscription “LIEBREICH’S OPHTHALMOSCOPE” in gold lettering. The instrument includes two condensing lenses for indirect ophthalmoscopy. The metal mirror confirms a date from the 1870s or later — a glass mirror replacement would indicate a more recent origin. This is an unsigned example, presenting a beautifully preserved miniature of one of the 19th century’s most significant ophthalmic instruments.
Who Was Richard Liebreich?
Richard Liebreich was born in East Prussia in 1830. He studied in Berlin and received his doctorate in 1853. He served as a preparator for Helmholtz — the inventor of the ophthalmoscope itself — in 1851. While assisting at Graefe’s clinic from 1854 to 1862, Liebreich published a celebrated treatise on ophthalmoscopy in the French edition of Mackenzie’s book. In 1862 he settled in Paris and published his famous atlas of ophthalmology. He later directed the ophthalmic section at St. Thomas’ Hospital in London from 1871 to 1878, before returning to Paris, where he died in 1917.

Liebreich’s Design Innovations
Liebreich first described his stand ophthalmoscope in 1855. That original design featured two short brass tubes adjusted by a screw thread. A metal concave mirror held by two double springs sat between them. The mirror rotated around the vertical axis and could be removed entirely. A second tube held a convex lens near the patient’s eye. It also rotated around the vertical axis. A small button at the end of a linked rod served as a fixation target. A camera lucida could project the image onto a table top. The instrument also featured a cushioned forehead and chin rest and a light shade. Petz and Flohr, opticians in Berlin, manufactured the original.
The Hand-Held Revolution
A pivotal moment came when Anagnostakis of Greece — training with Graefe from 1851 to 1854 — conceived the idea of making the instrument hand-held with a concave mirror. Liebreich adopted and refined this concept, sketching his preferred model in his 1857 treatise on ophthalmoscopy. The hand-held version entered production around 1860 and remained in use for nearly 50 years. By the 1870s, the metal mirror gave way to coated glass — making the metal mirror on this example a reliable dating indicator.
Rarity and Significance
Miniature versions of the Liebreich ophthalmoscope are genuinely uncommon. This example, complete with its gold-lettered case and two condensing lenses, represents a collector’s piece of the highest order. See our antique ophthalmoscope museum collection.
