HAAB reports the case of a patient through whose eyes had passed an electric current of unknown strength. For a short time he was blind. There were changes at the macula in the right eye which passed away in two months. These changes consisted in a delicate milky opacity in the entire macular region, and of a number of yellowish-white spots of irregular form and varying size, similar to those seen in old people and called colloid excrescences of the lamina vitrea.
