N2 - Microvascular pressures in retinal circulation were measured in living, anesthetized cat by the servonull micropuncture technique. Of the total vascular pressure drop 32% was in the segment proximal to the large retinal arteries when intraocular pressure was set at 10 mm Hg and decreased to 27% when intraocular pressure was increased to 20 mm Hg. The pressure in the retinal veins was substantially (>7 mm Hg) greater than intraocular pressure at both values of intraocular pressure. There was negligible pressure drop within venous segment; however, the pressure drop from the retinal veins to the systemic veins was large and cannot be explained on the basis of a venous waterfall within the retina.
