Christian Georg Theodor Ruete

Christian Georg Theodor Ruete (2 May 1810 – 23 June 1867) was a German ophthalmologist born in Scharmbeck, Lower Saxony.

In 1833 obtained his medical doctorate from the University of Göttingen, later serving as an assistant to Karl Gustav Himly (1772–1837).

He made modifications to Hermann von Helmholtz's ophthalmoscope by implementing a concave focusing mirror, and thereby introduced "indirect ophthalmoscopy" to allow for a stereoscopic and wider view of the fundus of the eye.

Ruete also conducted extensive research of ophthalmic disorders that included strabismus and hypermetropia.

[2] In 1845 Ruete published "Lehrbuch der Ophthalmologie für Aerzte und Studirende", a book that contained the first depiction of a visual migraine aura in European medical literature.
