ABSTRACT

Hermann von Helmholtz was born in Potsdam in 1821. He studied medicine in Berlin at the Friedrich Wilhelm Medical- Chirurgic Institute. With the philosophical influence of his father and his interest on organic physics, he made several studies, distinguishing:“About the conservation of force”, “Treatise of physiologic optic”, “About the realities of perception”.
In the winter of 1850, he showed a device consisting of a series of lenses which were located between the observer eye and the observed eye. A lighted candle was reflected over de lenses and this light passed trough the pupil illuminating the inside of the eye and in this way the fundus of the eye was observed.
This device denominated ophthalmoscope contributed in a very important way to the development of Ophthalmology.
