Marc Amsler

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.

Prior to assuming the position at Zurich, Dr. Amsler was chief ophthalmologist in Lausanne, since 1935.

[3] 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.

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.
