From the introduction: “The purpose of the present book is to bring together in a coherent manner new knowledge gained from research over the past 50 years on the physiology of intraocular pressure, ocular blood flow and the relation of these fundamental parameters to early diagnosis and therapy of vascular diseases of the eye and brain. It will be evident to the reader that the presentation is influenced significantly by the author’s own research. My justification is that by good fortune I have spent many years with superb collaboration helping solve outstanding problems of ocular physiology. This knowledge has increased understanding of the parameters underlying the onset of ischemia and the loss of autoregulation associated with common ocular disease and thereby led to new methods of diagnosis and therapy.”
