A technique is described which permits making simultaneous angiograms of the separate retinal and choroidal circulations following a single intravenous dye injection. The two sets of angiograms are made using a specially built optical separator with twin motorized 35 mm. cameras ivhich replaces the usual camera body on the standard Zeiss fundus camera. A single injection of solution containing a mixture of indocyanine green dye and sodium fluorescein dye is given to the subject, and the fundus camera with the attached optical separator is otherwise used in the usual manner to produce the angiograms. A technique for producing fluorescent indocyanine green dye in the human is also demonstrated.
