It has been reported in a preceding publication1 that in previously sympathectomized cats, when the connections of the ciliary ganglion to the inferior oblique and the inferior rectus muscles and to the unstriated retrobulbar muscle mass were severed, a controlled electric stimulus applied to the orbital parasympathetic pathway by means of a bipolar electrode produced a uniform response of the intraocular pressure in the stimulated eye. This was predictable with the highest degree of confidence. The response was characteristically a reduction in intraocular pressure.
The characteristics of this pressure response as well as the effect of various extraocular factors and of variation in stimulus characteristics were studied in 140 eyes. The results of this investigation are the subject of this communication.
The preparation as well as the equipment and techniques employed in these studies were described in the previous publication.1
