The episcleral vessels, however, contained blood and took on a yellowishgreen tint. This same investigator repeated Seidel's (1923) rabbit experiments by injecting India ink into the anterior chamber of a sarcomatous human eye. He reported that the episcleral vessels did not change color but that the aqueous veins were tinted black. It was felt that this demonstrated the communication of the anterior chamber with the aqueous veins.

More recent work by Greaves and Perkins,⁹ however, has revealed a failure of suspensions of India ink to appear in the aqueous veins of rabbits after injection into the . . . [Full Text PDF of this Article]
