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
Micropsia of the extracerebral visual pathways can also cause micropsia. EEG testing can diagnose patients with medial temporal lobe epilepsy. Epileptiform abnormalities including spikes and sharp waves in the medial temporal lobe of the brain can diagnose this condition, which can in turn be the cause of an epileptic patient's micropsia. The Amsler grid test can be used to diagnose macular degeneration. For this test, patients are asked to look at a grid, and distortions or blank spots in the patient's central field of vision can be detected. A positive diagnosis of macular degeneration may account for a patient's micropsia. A
