Influence of the Sympathetic Nervous System on the Intra-Ocular Pressure and Vascular Circulation of the Eye

THE first section of the following paper describes the effects on the intra- ocular pressure of cutting and stimulating the cervical sympathetic nerves in cats and rabbits. This section is a repetition of previous workers' experiments, except that we have recorded simultaneously on the same film the intra-ocular pressure of both eyes and the blood pressure, thus enabling intra-ocular pressure changes resulting from general blood pressure effects to be distinguished from local sympathetic effects.
