Otto Haab

Otto Haab (April 19, 1850 - October 17, 1931) was a Swiss ophthalmologist who was a native of Wülflingen, which today is a district in the city of Winterthur. In 1875 he obtained his doctorate from the [University of Zurich, where, as a student, he was an assistant to Karl Joseph Eberth in pathological anatomy. In 1886 he succeeded Johann Friedrich Horner as professor of ophthalmology at Zurich, a position he held until 1919.

Otto Haab made contributions involving pathological anatomy of the eye, as well as treatment of eye-related lesions. In 1885 he clinically described senile macular degeneration, and investigated the atrophic and pigmentary changes in the macular region of the eye associated with the condition. His name is associated with several medical eponyms, including "Haab's reflex", which is another name for pupillary light reflex, and "Haab's magnet", a powerful magnet used for removing metallic particles from the eye. Also, the "Haab scale" is a device used to measure pupillary diameter, and "Haab's striae" are horizontal breaks in the Descemet membrane associated with congenital glaucoma.
