The retrobulbar injection of procaine has become almost a standard preoperative procedure in ophthalmology; yet its mode of action on the ocular tension is still unknown. Several recent papers * have described the effect of the retrobulbar injection of anesthetic agents on the intraocular pressure, both in normal and in glaucomatous eyes. Thus far, however, the interest of the research workers has centered mainly on the changes in the intraocular pressure, while other aspects of the aqueous humor dynamics were not considered. It was thought that by employing Grant's tonographic technique,³ further information might be obtained concerning the mode of action of the retrobulbar injection of anesthetic agents on the intraocular pressure and on other aspects of aqueous humor dynamics. Furthermore, this procedure might throw some light on the neurovascular theory of glaucoma, since the retrobulbar injection effectively blocks all or most of the nerve supply of the eye. Therefore, . . . [Full Text PDF of this Article]
