Channels of Aqueous Outflow and Related Blood Vessels: III. Episcleral Arteriovenous Anastomoses in the Rhesus Monkey Eye (Macaca mulatta)

Arch Ophthalmol. 1970;84(6):770-775. doi:10.1001/archopht.1970.00990040772016

Arteriovenous anastomotic vessels in the anterior episcleral vessel network of 32 rhesus monkey eyes were delineated with 3% silver nitrate, India ink-gelatin mixture, and colored, room-temperature vulcanizing liquid silicone compound. These vessels have inside diameters of 10μ to 30μ and have muscular walls either throughout their entire length or for a short distance near their arterial origin. They usually follow a fairly direct course from artery to vein and are capable of shunting fluid flow at physiologic pressures.
