This monograph, translated into English by Robert Fraser, appeared as supplement 17 of the Acta ophthalmologica. In chapter 1 the vascular circulation is discussed under subheads of general, vasomotor innervation of the cerebral arteries and vasomotor innervation of the retinal arteries. In these the author presents a comprehensive review of the literature. Chapter 2 reviews the vascular anatomy of the globe. In chapter 3 the author describes his method. He used cats and anesthetized with intramuscular injections of 0.5 to 0.6 cc. per kilogram of body weight of butyl-bromallyl-malonylurea in divided doses. The pupils were dilated with atropine. The retinal vessels were viewed with a Leitz Ultrapak microscope with a contact glass on the cornea. Recordings of vessel changes were made by the method devised by Fog. Caliber of the vessels was measured following intravenous injections, electrical stimulation and changes in intracranial pressure. Blood pressure and intraocular pressure were also
