The determination of the diffusion coefficient of krypton in rabbit ocular tissue.
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.
