眼睛独特的解剖和功能特性给开发一种可靠、准确的测量眼血流的方法带来了巨大的障碍。最近在估计其他组织的局部血流的概念和技术方面的改进具有相当大的潜力来解决其中的几个障碍。大小适中的核素标记微球的问世，提供了一种分数分布的非循环指示器，为眼部血流量测量提供了一种直接可重复性的技术。本文描述了我们对放射性微球用于测量兔和猴眼的总血流量和节段性血流量的初步观察。
The unique anatomical and functional properties of the eye present formidable obstacles in the development of a reliable, accurate method for measuring ocular blood flow. Recent refinements in concepts and techniques for estimating regional blood flow in other tissues have considerable potential for resolving several of these obstacles. The advent of nuclide labeled microspheres of appropriate size to impact in the vascular bed has provided a nonrecirculating indicator of fractional distribution, permitting a direct reproducible technique for ocular blood flow measurement This report describes our preliminary observations on the use of radioactive microsphere in measuring total and segmental blood flow in rabbit and monkey eyes.
