The First Ophthalmoscope? Adolf Kussmaul 1845

The History of Detecting Glaucomatous Changes in the Optic Disc

“…Several workers had tried to visualize the inside of the eye but had fallen short of putting it all together. Kussmaul (known for "Kussmaul'sairhunger") described the imaging principles in a thesis in 1845 [23]but failed to solve the illumination problem. Cumming [24](1846) in England and Brücke [25](1847) in Germany had shown that a reflection from the fundus could be obtained by bringing the light source in line with the observer, but they failed to solve the imaging problem.…”

Adolf Kussmaul (1822-1902), su biografía y descripciones

“…Las investigaciones de Müller en la fi siología ocular incentivaron a Kussmaul en ese tema, por lo que desarrolló una tesis relacionada con los cambios de color en la retina. También inventó, en 1845, mientras era aún un estudiante, el primer oftalmoscopio complejo que, años después, Hermann Ludwig von Helmholtz (1821-1894) reformó y así, su inventor fue el pionero de la oftalmología moderna 2 . En 1847 visitó Viena y conoció a Joseph Skoda (1805-1881) a quien admiró por su excelencia en el examen físico, y en el Hospital General de esa ciudad, conoció a Ferdinand Ritter von Hebra (1816-1880) y sus primeras incursiones en la dermatología, continuando en este campo, en Praga, bajo la dirección de Johannes Oppolzer (1808-1871) 3 .…”

Adolf Kussmaul: Distinguished Clinician and Medical Pioneer

“…Kussmaul began his work on creating a tool that could view the interior of the eye at the age of 23, at which time he was a medical student in Heidelberg, Germany. 25 In 1845, he wrote a dissertation entitled "Die Farbenerscheinungen im Grunde des menschlichen Auges" ("An Important Description of Colour Phenomena in the Fundus Oculi"), which contained the blueprint for construction of an ophthalmoscope. 25 Despite a problem with the fundamental optics of the device, which would later be corrected by Hermann von Helmholtz, Kussmaul undoubtedbly played an integral role in the creation of the ophthalmoscope and provided physicians with a tool that enabled them to better understand and treat diseases associated with the interior of the eye.…”
