Abstract
Oscillatory changes in the intraocular volume of lower frequency than pulse and breathing have been observed. They were sizeable under the experimental conditions of the present study. The oscillatory waves are suggested to be due to vasomotor innervation, as found in muscles, but it was not possible to affect them by retrobulbar anesthesia nor by blockade of the stellate ganglion. Following inhalation of 7 % CO2 (carbogen gas) there was an almost immediate decrease in displaced volume (average 10 i(m1) considered to be due to an increase in blood content of the eye. There was a negligible effect following inhalation of pure oxygen.
