Erich Seidel (1882–1946) was a German ophthalmologist known for his studies in the field of
glaucoma, ocular
anesthesia
Anesthesia is a state of controlled, temporary loss of sensation or awareness that is induced for medical or veterinary purposes. It may include some or all of analgesia (relief from or prevention of pain), paralysis (muscle relaxation), ...
and
aqueous humor dynamics.
Seidel test and
Seidel's scotoma are named after him.
Biography
Erich Seidel was born on 1882 December 30 at
Apolda,
Thüringen,
Germany.
He received MD from Jena in 1907 (Topic: über die Lidbildung mittels übertragener stiellser Hautlappen (eyelid formation by means of transferred skin flaps)).
After specialising in Ophthalmology during 1907-1910, he began working as an assistant at the
University of Heidelberg Eye Clinic in 1910 and was appointed Head Physician in 1916 and Ausserordentlicher Professor in 1919.
In 1935 he was offered to join at the
University of Gottingen

, but he rejected.
Receiving habitation in Heidelberg in 1914, his inaugural address was on the problems of spectacle glasses and solutions through modern spectacle optics.
He spent his last days in
Jene

He died on February 26, 1946.
Scientific contributions
Seidel studied the formation of
aqueous humor in the
ciliary body and the flow of aqueous humor through the
Schlemm's canal, and attempted to explain the movement of aqueous humor experimentally.
In the year 1914 Seidel invented a darkroom provocative test to detect
glaucoma. In the same year he also described a glaucomatous
Visual field defect which is now known as
Seidel sign
Seidel's sign (also called Seidel's scotoma) is a sickle-shaped scotoma that is a superior or inferior extension of the blind spot. It occurs in some patients with glaucoma.
History
In 1914, German ophthalmologist Erich Seidel first described th ...
or Seidel's scotoma. In this scotoma the
blind spot of the eye enlarges vertically into a sickle cell shape.
In 1921 he described a test to assess the presence of
aqueous humor leakage from the
anterior chamber of the eye, which is known as
Seidel test now.
