Abstract: | The permeability of the corneal endothelium and its aqueous-cornea distribution ratio were reevaluated in the rabbit eye. Both parameters were determined in an individual eye by applying the dye first by iontophoresis and then by intravitreal injection, which allows the influence of fluorescein glucuronide on the fluorophotometric measurements to be excluded. The corneal endothelial permeability coefficient was 5.13 +/- 1.64 X 10(-4) cm min-1, and the aqueous-cornea distribution ratio was 0.25 +/- 0.06 (mean +/- S.D., n = 11) on the average, and the former was considerably greater than the previous results, while the latter was considerably smaller. |
