The details of a successful technique for fluorescence angiography of the rhesus monkey's fundus are outlined. The angiographic pattern in this primate is quite similar to that of man, thus making the rhesus monkey an excellent experimental animal for retinal and choroidal circulation studies. The dynamics of normal retinal and choroidal circulation can best be appreciated with rapid sequence photography. Initial arterial, choroidal, venous, and capillary phases are followed by second arterial, choroidal, venous, and capillary phases, which are assumed to represent recirculation.
