A Tribute to the Work of the Dartmouth Discoverers of Aniseikonia

DR. ALFRED A. BIELSCHOWSKY, eminent German ophthalmologist, arrived in Hanover in November from Breslau to begin six months of special work in the department of research in Physiological Optics of the Dartmouth Medical School. Dr. Bielschowsky, an authority on motor anomolies of the eyes and until recently professor of Ophthalmology and chief of the eye clinic at the University of Breslau, will work with members of the Dartmouth research department on the analysis of abnormalities of vision. The arrival of Dr. Bielschowsky at

tached a new importance to the farfamed work of the department. He has won outstanding distinction abroad as an authority on diseases of the eye. Among the many noted medical men who have become interested in the clinic at Dartmouth no one speaks with more authority than Dr. Bielschowsky. At the request of the editors, he has prepared the following appraisal of the department's work:

"Through the kind invitation of Professor Ames, 1 have been enabled to joinhim and his associates in the researchwork of the department of research inPhysiological Optics. I am highly impressed by the remarkable results achievedby the department within a few years andam impressed just as much by the exemplary harmony among all the membersof the department. The department hasdiscovered that the retinal images of anobject very frequently are of different sizeand shape in both eyes. This fact, hitherto unknown, is of great importance notonly from the physiological, but alsofrom the clinical point of view. For it hasbeen ascertained that eye-strain, headache and other troubles, in many cases arecaused by a difference in the size andshape of the retinal images and could beremoved, or at least mitigated by glassescorrecting that difference. To what extentthe latter may be responsible for otherocular disturbances, the origin of whichcould not be determined heretofore, is aproblem to which the research department is devoting itself at present."
