As to the symptoms in man, Mueller¹was the first who, by giving deoxypyridoxine, developed them. Since then, Schreiner,²Vilter,³and other researchers have reported on this subject. In the field of ophthalmology, however, experimental reports on this subject are very few and the symptoms are still indefinitely known.
