Eichhorst made contributions in several fields of medicine. In a 1878 monograph he documented one of the earliest descriptions of progressive pernicious anemia. He also discovered globular forms in the poikilocytosis of this disease, which were to become known as Eichhorst's corpuscles. In 1896 and 1913 Eichhorst provided the earliest comprehensive accounts of infantile and hereditary multiple sclerosis. He also described a form of interstitial neuritis that is sometimes referred to as Eichhorst's neuritis.
