Most of the fluorescence angiography of the ocular fundus, since its introduction in 1961 by Novotny and Alvis,1 has been done on 35-mm films of moderate to high speed2 and some on cinematography films.3,4 Several combinations of filters have been used for exciting fluorescence and eliminating the unused exciting light. In this communication a method for obtaining instant positive prints on Polaroid film, in stereoscopic view if desired, is presented. The necessary alterations of the Zeiss fundus camera are referred to and the choice combination of exciting and photographing filters is given. A few new observations and interpretations of fluorescing structures as seen in stereoscopic views are given.

Equipment  The Zeiss fundus camera as modified by Stenstrom5 and Allen6-8 is combined with the 2× accessory lens (5×, final magnification) and a Vertex adapter * for a Polaroid 3½ × 4½-inch 3,000 ASA film pack.† The film
