notes: label: Description
content: “In the whole history of medicine there is no more beautiful episode than the invention of the ophthalmoscope, and physiology has few greater triumphs.” So wrote Edward Greely Loring (1837-1888) on the first page of his <i>Textbook of Ophthalmology</i> (New York, 1886).
label: Description
content: Loring introduced his first ophthalmoscope to the American Ophthalmological Society in 1869, noting that it could be had from H. W. Hunter, a local optician. A modification of Helmholtz’s instrument, this had several small lenses on the edge of a disc behind the mirror that could be rotated by the forefinger to bring the lens best suited to the refraction of the eye under examination. An inscription on the box of this example reads “LORING / OPHTHALMOSCOPE.”
