Colored room-temperature vulcanizing liquid silicone compound was used to delineate blood vessels and aqueous vessels and their interconnections in the anterior segment of the rhesus-monkey eye. Blood vessels were injected via the anterior and posterior ciliary arteries and the aqueous vessels via the anterior chamber, Schlemm's canal, and the aqueous veins. Following injection, the globes were cleared and the topographical relationships and connections between the blood vessels and the aqueous outflow channels were examined under magnification. Schlemm's canal was found to be drained by large and fine intrascleral vessels which emptied into the anterior ciliary veins. No arterial communications with the canal were seen. Intrascleral aqueous outflow channels and anterior ciliary veins had no connections with the uveal vasculature. In the episclera, however, many direct arteriovenous shunts were demonstrated.
