Circulation of the Aqueous

Electrochemical Changes Associated With the Formation of the Aqueous Humour

“…Ussing, 1959). This possibility is not entirely dissimilar from that which was investigated by Friedenwald and Stiehler (1938), who were able to alter the direction of aqueous flow by imposing an electrical potential across the blood-aqueous barrier of both eyes in rabbits. The magnitude of the external E.M.F.…”

“…The magnitude of the external E.M.F. (20V) in their experiments has been criticized, not unjustifiably, by Davson (1956) as being unphysiological, but since Friedenwald and Stiehler (1938) did not measure the blood-aqueous P.D. it is possible that the potential which they actually imposed across the blood-aqueous barrier was not so large as might appear at first sight.…”

The Mechanism of Aqueous Humor Formation Inferred From Chemical Studies on Blood-Aqueous Humor Dynamics

“…Evidence in favor of the secretory hypothesis, as previously mentioned, has been largely negative, in that it has been based on the erroneous assumption that equilibrium ratios below 1 could not be accounted for except on the assumption of a secretory hypothesis. On the other hand Friedenwald and Stiehlet (6) have found that the epithelium of the ciliary body exhibits a selective permeability to basic and acid dyes. Friedenwald and coworkers have found that the mechanism for ion transport is one of oxidation and reduction.…”
