This report will be limited by request to the use of the galvanic and the form of alternating current known as the sinusoidal. That the subject of electricity in ophthalmic practice has received scant attention appears from a statement by the secretary of this section, Dr. Bulson: "For several years the subject has received no consideration. In 1898 Dr. Starkey read a paper on 'The Use of Galvanism in Pterygium,' and Dr. LeMond on 'The Value of Faradism in Choroiditis.'

It is probably safe to say that there is no remedy which causes so varied physiologic manifestations and therapeutic results as electricity. By proper selection of modality, current strength, tension, polarity, length and frequency of application, etc., stimulation or sedation of the nervous and vasomotor systems, muscular contraction, decomposition and destruction of tissue, changes
