The various disease processes which produce retinal vascular fundus disease are usually of a progressive nature. In most of these conditions the changes in the vessels occur slowly and little is known of the true mechanisms attending them. Some authors believe that the most important pathologic variations occur within the capillary bed, and in the case of hypertension, retinal hemorrhages and edema follow capillary decompensation. According to this concept it is extremely important to investigate the blood pressure of the retinal vessels and correlate changes in caliber with changes in pressure. At the present time only one clinical method has been recommended for the determinations. This method is called tonoscopy or ophthalmodynamometry. It is the purpose of this paper to discuss its application to the study of retinal vascular fundus disease.
