Liebreich ophthalmoscope in case, by J. Weiss and Son Limited, 62 Strand, London, England, 1855-1865.
An ophthalmoscope is used to view the retina of the eye. It was invented in 1851 by Herman von Helmholtz (1821-94). This simple ophthalmoscope was adapted by pioneering German ophthalmologist Richard Liebreich (1830-1917). It was made by J. Weiss and Son of London. It is seen here with two pairs of spectacles. These correct long or short sightedness in the observer, two conditions that could affect the physician’s ability to diagnose by sight.
