Abstract
Measurement of intraocular blood flow has been difficult because of the size and inaccessibility of the ocular blood vessels. Recently, a method was developed using labeled microspheres for studying regional blood flow rates. Using this technique we have begun to study the various parameters which control ocular blood flow. This study confirms the use of labeled microspheres as a valid method for measuring blood flow. We have measured intraocular blood flow in the cat and have shown an inverse relationship between intraocular blood flow and intraocular pressure
