The validity of the inert gas clearance method for measuring choroidal blood flow has recently been demonstrated by studying the diffusion of krypton in ocular tissue. In this study the diffusion coefficients of krypton in rabbit ocular tissue were calculated from measurements of the diffusion coefficients of xenon. The mean values for the diffusion coefficients of krypton obtained in this study were 1.6 X 10(-5), 0.76 X 10(-5), 0.80 X 10(-5), and 1.2 X 10(-5) cm.2 per second for the sclera, choroid, retina, and vitreous, respectively.
最近通过研究氪在眼组织中的扩散,证明了惰性气体清除法测量脉络膜血流的有效性。在本研究中,氪在兔眼组织中的扩散系数是根据氙扩散系数的测量值计算得出的。本研究中获得的氪扩散系数平均值,巩膜、脉络膜、视网膜和玻璃体分别为每秒1.6×10⁻⁵、0.76×10⁻⁵、0.80×10⁻⁵和1.2×10⁻⁵平方厘米。
