SODIUM, CHLORIDE AND PHOSPHORUS MOVEMENT AND THE EYE

Abstract

The rate of accumulation of sodium, chloride and phosphorus in the normal anterior chamber of the rabbit was determined after isotopes of these elements possessing artificially induced radioactivity were introduced into the blood. This research is an extension of the recent study made by some of us¹ in which it was shown that water in the anterior chamber exchanges with that in the blood stream at a rate greatly in excess of the so-called rate of formation of whole aqueous. A comparison of the rate of water movement (50 cu. mm. per minute) with that given for formation of the whole aqueous² (1 to 2 cu. mm. per minute) would suggest that some other constituents, such as sodium or chloride, enter the anterior chamber at a rate considerably less than would be indicated by their final concentrations in the aqueous (about one unit of sodium chloride per hundred
