Marc Amsler 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, so that macular degeneration can be identified. He also contributed to the progress in the understanding of uveitis. Furthermore, he published works on keratoconus. In 1951, Dr. Amsler performed the first corneal transplantation at the Zurich Eye clinic. Marc Amsler Marc Amsler
