Abstract 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 References 1.

Filters used by others have not given us enough exposure because of our greater magnification, even though our 3,000-speed film has been faster. Mr. H. L. Gibson of Eastman Kodak Co. recommended trying Wratten filter 47-A in the illuminating system for exciting the fluorescein. This filter transmits a much larger total quantity of blue and violet light than do others. Specifically, it transmits 38.6% of the 49-mμ wavelength—said to be the most effective in exciting blood-fluorescein mixtures.1 In contrast, No. 47 transmits only 19.6% and 47-B only 1.3%. For this reason, we prefer 47-A. Experiments by Novotny and Alvis have shown that blood-fluorescein mixtures can fluoresce at 520-mμ wavelength. We have not tried to confirm this. Filter 56 (used by others to absorb all unused exciting light) transmits 78.8% of wavelength 520 mμ while the filter we are using, No. 15, passes only 19.4%. With a given light intensity setting on the camera and through filters 47 with 56, the contrast on the film is not as good as through 47-A with 15. While we like the contrast with still another combination, 47 with 15, it does not give enough exposure. Until a better filter combination, preferably one with no overlapping, is available, we prefer No. 47-A with 15. 8. Moore Kirk Laboratories, Worcester, Mass. 9.
