Marc Amsler (born 5 February 1891 in Vevey, Switzerland – died 3 May 1968) was a professor of ophthalmology in the Eye Clinic at the University of Zurich. He took the position as professor of ophthalmology in Zurich in 1944. His predecessor was Prof. Alfred Vogt. Prior to assuming the position at Zurich, Dr. Amsler was chief ophthalmologist in Lausanne, since 1935. His predecessor there, under whom he worked beforehand, was Jules Gonin. During his time in Lausanne, Amsler was instrumental in creating the Jules Gonin Medal which is awarded every four years and is considered the highest honor in ophthalmology. Amsler was professor and chief of the Zurich Eye Clinic until 1961. His successor was Rudolf Witmer. He is best known for the Amsler grid test. The Amsler grid was an improvement over the initial work done by the ophthalmologist Edmond Landolt. The grid tests the function of the macula, a part of the retina, and enables patients to self-test for and monitor metamorphopsia, a symptom of early stages of macular degeneration. He also contributed to the progress in the understanding of uveitis. Furthermore, he published works on keratoconus. In 1951, Amsler performed the first corneal transplantation at the Zurich Eye Clinic.
